UPDATED: January 2019
Last September, consumers began to see the first service bundles offered by telecommunications companies in their area, marketed with some form of the term “5G.” “5G is here,” declared Verizon CEO Hans Vestberg, specifically for cities such as Sacramento, Los Angeles, and Indianapolis where rival AT&T had already been drumming up excitement around its 5G trials.
It was a bit like SpaceX’s 2016 announcement, its 2017 announcement, and its 2018 announcement that the race to Mars had begun.

5G Wireless is an explicit set of technologies specified by the 3rd Generation Partnership Project (3GPP) as “Release 15” and “Release 16.” 3GPP is an organization consisting of essentially all the world’s telecommunications standards bodies who agreed to share the definition of 3G Wireless, and to move on from there to successive generations.
Who gets to say what 5G really is and isn’t
Today, 3GPP specifies which technologies constitute 5G Wireless and, by exclusion, which do not. 5G is an effort to create a sustainable industry around the wireless consumption of data for all the world’s telcos. One key goal of 5G is to dramatically improve quality of service, and extend that quality over a broader geographic area, in order for the wireless industry to remain competitive against the onset of gigabit fiber service coupled with Wi-Fi.
The 5G transition plan, once complete, would constitute an overhaul of communications infrastructure unlike any other in history. Imagine if, at the close of the 19th century, the telegraph industry had come together in a joint decision to implement a staged transition to fax. That’s essentially the scale of the shift from 4G to 5G. The real reason for this shift is not so much to get faster as to make the wireless industry sustainable over the long term, as the 4G transmission scheme is approaching unsustainability faster than the industry experts predicted.

To make the transition feasible in homes and businesses, telcos are looking to move customers into a 5G business track now, even before most true 5G services exist yet. More to the point, they’re laying the “foundations” for technology tracks that can more easily be upgraded to 5G, once those 5G services do become available.
New business models
The initial costs of these infrastructure improvements may be tremendous, and consumers have already demonstrated their intolerance for rate hikes. So to recover those costs, telcos will need to offer new classes of service to new customer segments, for which 5G has made provisions. These include:
- Fixed wireless data connectivity in dense metropolitan areas, with gigabit-per-second or better bandwidth, through a dazzling, perhaps bewildering, new array of microwave relay antennas;
- Edge computing services that bring computing power closer to the point where sensor data from remote, wireless devices would be collected, eliminating the latency incurred by public cloud-based applications;
- Machine-to-machine communications services that could bring low-latency connectivity to devices such as self-driving cars and machine assembly robots;
- Video delivery services that would compete directly against today’s multi-channel video program distributors (MVPD) such as Comcast and Charter Communications, perhaps offering new delivery media for Netflix, Amazon, and Hulu, or competing against them as well.
“It’s not only going to be we humans that are going to be consuming services,” remarked Nick Cadwgan, director of IP mobile networking, speaking with ZDNet. “There’s going to be an awful lot of software consuming services. If you look at this whole thing about massive machine-type communications [mMTC], in the past it’s been primarily the human either talking to a human or, when we have the internet, the human requesting services and experiences from software. Moving forward, we are going to have software as the requester, and that software is going to be talking to software. So the whole dynamic of what services we’re going to have to deliver through our networks, is going to change.”
Driving for higher yields
5G is comprised of several technology projects in both communications and data center architecture, all of which must collectively yield benefits for telcos as well as customers, for any of them to be individually considered successful. The majority of these efforts are in one of three categories:
- Spectral efficiency — Making more optimal use of multiple frequencies so that greater bandwidths may be extended across further distances from base stations (historically, the main goal of any wireless “G”);
- Energy efficiency — Leveraging whatever technological gains there may be for both transmitters and servers, in order to drastically reduce cooling costs;
- Utilization — To afford the tremendous communications infrastructure overhaul that 5G may require, telcos may need to create additional revenue generating services such as edge computing and mobile apps hosting, placing them in direct competition with public cloud providers.
It was during the implementation of 4G that telcos realized they wished they had different grades of infrastructure to support different classes of service. 5G allows for three service grades that may be tuned to the special requirements of their customers’ business models:
- Enhanced Mobile Broadband (eMBB) aims to service more densely populated metropolitan centers with downlink speeds approaching 1 Gbps (gigabits-per-second) indoors, and 300 Mbps (megabits-per-second) outdoors. It would accomplish this through the installation of extremely high-frequency millimeter-wave (mmWave) antennas throughout the landscape — on lampposts, the sides of buildings, the branches of trees, existing electrical towers, and in one novel use case proposed by AT&T, the tops of city busses. Since each of these antennas, in the metro use case, would cover an area probably no larger than a baseball diamond, hundreds, perhaps thousands, of them would be needed to thoroughly service any densely populated downtown area. And since most would not be omnidirectional — their maximum beam width would only be about 4 degrees — mmWave antennas would bounce signals off of each other’s mirrors, until they eventually reached their intended customer locations. For more suburban and rural areas, eMBB would seek to replace 4G’s current LTE system, with a new network of lower-power omnidirectional antennas providing 50 Mbps downlink service.
- Massive Machine Type Communications (mMTC) [PDF] enables the machine-to-machine (M2M) and Internet of Things (IoT) applications that a new wave of wireless customers may come to expect from their network, without imposing burdens on the other classes of service. Experts in the M2M and logistics fields have been on record saying that 2G service was perfectly fine for the narrow service bands their signaling devices required, and that later generations actually degraded that service by introducing new sources of latency. MMTC would seek to restore that service level by implementing a compartmentalized service tier for devices needing downlink bandwidth as low as 100 Kbps (kilobits-per-second, right down there with telephone modems) but with latency kept low at around 10 milliseconds (ms).
- Ultra Reliable and Low Latency Communications (URLLC) would address critical needs communications where bandwidth is not quite as important as speed — specifically, an end-to-end latency of 1 ms or less. This would be the tier that addresses the autonomous vehicle category, where decision time for reaction to a possible accident is almost non-existent. URLLC could actually make 5G competitive with satellite, opening up the possibility — still in the discussion phase among the telcos — of 5G replacing GPS for geolocation.
Plotting the “inflection point”
“The first generation of mobile systems that were launched around 1991 — popularly known as 2G/GSM — was really focused on massive mobile device communication,” explained Sree Koratala, head of technology and strategy for 5G Wireless in North America for communications equipment provider Ericsson, speaking with ZDNet. “Then the next generation of mobile networks, 3G, launched starting in 1998, enabled mobile broadband, feature phones, and browsing. When 4G networks were launched in 2008, smartphones popularized video consumption, and data traffic on mobile networks really exploded.
“All these networks primarily catered towards consumers,” Koratala continued. “Now when you look at this next generation of mobile networks, 5G, it is very unlike the previous generation of network. It’s truly an inflection point from the consumer to the industry.”
The full release of the first complete set of 5G standards (officially “Release 15”) by 3GPP took place in June 2018. By the end of 2019, the organization expects to declare a supplemental set of 5G standards called “Release 16.” That release is slated to include specifications for:
- Vehicle-to-Everything (V2X) communications, which would incorporate low-latency links between moving vehicles (especially those with autonomous driving systems) and cloud data centers, enabling much of the control and maintenance software for moving vehicles to operate from within stationary, staffed, and maintained data centers.
- Satellite access, which may include the ability for satellite transmission to fill in gaps for under-served or geographically remote areas.
- Wireline convergence, which would finally deliver the outcome that AT&T famously warned Congress was absolutely necessary for the communications industry to survive: the phasing out of separate wireline service infrastructure and the deconstruction of the old telephone lines and circuit-switched networks that were the backbone of the Bell System, and other state-sanctioned monopoly service providers of the 20th century.
Are “5G Evolution” and other intermediate steps necessary for 5G?
The true purpose of 5G Wireless, as you’ll see momentarily, is to produce a global business model where expenses are lower and revenue from services is higher, on account of the presence of more and greater services than 4G could provision for. So there is a valid argument, from a marketing standpoint, in favor of a gradual deconstruction of 4G branding. As consumers hear more and more about the onset of 5G, enumeration leaves them feeling more and more like their 4G equipment is old and obsolete.
With so many technologies under the 5G umbrella — home broadband, office broadband, home television, Internet of Things, in-vehicle communication, as well as mobile phone — there’s no guarantee that, when it comes time, any consumer will choose the same provider for each one unless that consumer is willing to sign a contract beforehand. That’s why telcos are stepping up their 5G branding efforts now, including rolling out preliminary 4G upgrades with 5G monikers, and re-introducing the whole idea of 5G to consumers as a fuzzy, cloudy, nebulous entity that encapsulates a sci-fi-like ideal of the future.
“The general purpose technology for the Fourth Industrial Revolution is actually the ambiguous sort of connectivity that 5G can bring,” admitted Verizon CEO Hans Vestberg, in no less conspicuous an arena than the keynote address of CES 2019.
“So what is 5G? 5G is a promise,” Vestberg continued, “of so much more than we’ve ever seen in any wireless technology. From the beginning, we had the 1G, the 2G, the 3G, and the 4G. They were sort of leaps of differences, when it comes to speed and throughput. When we think about 5G, we think about 10 gigabits per second throughput, we talk about 10x battery life, we think about 1000 times more data volumes in the networks. It’s just radically different. I would say it’s a quantum leap compared to 4G.”
The first wave of 5G-branded services are effectively 4G, or 4G extensions, that place consumers on the right track for future 5G upgrades, thus guaranteeing the revenue sources that 5G will require to be successful, or if only to just break even.
- Verizon’s “First on 5G” began with the October 2018 rollout of what’s being called 5G Home — a broadband Wi-Fi service that bundles wireless phone with no-longer-cable TV service, for a price that, after short-term discounts, could rise to as much as $120/month. In the test cities where it was first deployed, 5G Home may utilize wireless spectrum that is indeed being earmarked for 5G. Yet it involved a grade of equipment only capable of 300 megabits-per-second (Mbps) throughput, that would eventually need to be upgraded to 1 gigabit-per-second (Gbps) for it to qualify as 5G technology. In January 2019, Verizon CEO Hans Vestberg indicated to financial analysts that 5G Home rollout may remain limited to the initial test area for some time to come, as the company awaits new standards for customer premise (CP) equipment, probably as part of 3GPP’s Release 16. This after it seemed clear to observers that Verizon was willing to continue rolling out intermediate equipment with a “5G” brand until that time.
- AT&T’s “5G Evolution” began in December 2018 with the sudden, unanticipated appearance of a “5G E” icon in the notifications area of 4G customers’ phones. The icon appears if the phone is presently being serviced by a 4G LTE transmitter capable of being upgraded to 5G specifications. Those transmitters may have begun using frequencies over and above those originally reserved for 4G LTE, in addition to those already being used, for greater multiplexing and presumably greater bandwidth, although phones may not necessarily be equipped to receive these extra frequencies, even if they show the “5G E” icon.
- AT&T’s “5G+” also began in December 2018, and refers to a mobile hotspot service that uses an early version (some would say “prototype”) of the very-high-speed mmWave technology that is being earmarked for 5G, in addition to existing 4G LTE. The hotspot device itself (Netgear’s Nighthawk 5G Mobile Hotspot) will be sold separately by AT&T for $499, while it offers the service for $70 per month for the first 15 GB. With a theoretical peak throughput of 300 Mbps, it’s conceivable that this device’s initial bandwidth allocation could be completely burned through in less than seven minutes’ time.
- T-Mobile has said it plans to launch what it characterizes as “true 5G service” to select cities, very soon after the finalization of its merger agreement with Sprint. In a statement, the company says it will need access to the mid-range of 5G spectrum currently delegated for Sprint, in addition to the low- and high-range spectrum T-Mobile currently holds, to deliver the first wave of its services. At the time of this writing, the ongoing federal government shutdown appears to have interfered with these plans.
But consumers aren’t the only parties facing down the need to climb onto a new track. Telcos have their own service providers — for example, Nokia, which has absorbed the assets of the former Alcatel-Lucent, and is now the holder of the massive Bell Laboratories intellectual property portfolio. These providers also need their customers to get with the program. In a January 22 blog post, Nokia’s marketing strategist Clare McCarthy stated that communications service providers (CSPs) can start small if they want, but to become fully 5G compliant, they’ll eventually have to overhaul their communications infrastructure completely. McCarthy wrote:
CSPs can start small by upgrading their radio access software and and maintaining the connection to an existing LTE core network if increased capacity is all they need, but capacity is not all CSPs need. They see their role as central to a flourishing digital economy. They need to offer new digital services and support new operating and business models across industry verticals — and this requires more than a radio-only upgrade. Delivering a new kind of business requires a network capable of higher speeds, greater spectral efficiency, a cloud native core and a coherent, end-to-end framework. CSPs need to deploy a fundamentally different infrastructure to meet the needs for greater capacity, latency and extreme reliability.
Why cooling made 5G an urgent necessity
In May 2017, AT&T President of Technology Operations Bill Hogg declared the existing wireless business model for cell tower rental, operation, and maintenance “unsustainable.” Some months earlier, a J. P. Morgan analyst characterized the then-business model for wireless providers in Southeast Asia as unsustainable, warning that the then-current system has rendered it impossible for carriers to keep up with customer demand. And as research firm McKinsey & Company asserted in a January 2018 report, the growth path for Japan’s existing wireless infrastructure is becoming “unsustainable,” rendering 5G for that country “a necessity.”
One senses a theme.
The world’s telcos need a different, far less constrained, business model than what 4G has left them with. The only way they can accomplish this is with an infrastructure that generates radically lower costs than the current scenario, particularly for maintaining, and mainly cooling, their base station equipment.

Cooling and the costs associated with facilitating and managing cooling equipment, according to studies from analysts and telcos worldwide, account for more than half of telcos’ total expenses for operating their wireless networks. Global warming (which, from the perspective of meteorological instrumentation, is indisputable) is a direct contributor to compound annual increases in wireless network costs. Ironically, as this 2017 study by China’s National Science Foundation asserts, the act of cooling 4G LTE equipment alone may contribute as much as 2 percent to the entire global warming problem.
The world’s biggest example
The 2013 edition of a study by China Mobile, that country’s state-licensed service provider, examined the high costs of maintaining energy-inefficient equipment in its 3G wireless network, which happens to be the largest on the planet in both territory and customers served. In 2012, CM estimated its network had consumed 14 billion kilowatt-hours (kWh) of electricity annually. As much as 46 percent of the electricity consumed by each base station, it estimated, was devoted to air conditioning.
That study proposed a new method of constructing, deploying, and managing network base stations. Called Cloud architecture RAN (C-RAN), it’s a method of building, distributing, and maintaining transmitter antennas that history will record as having triggered the entire 5G movement.

One of the hallmarks of C-RAN cell site architecture is the total elimination of the on-site base band unit (BBU) processors, which were typically co-located with the site’s radio head. That functionality is instead virtualized and moved to a centralized cloud platform, for which multiple BBUs’ control systems share tenancy, in what’s called the baseband pool. The cloud data center is powered and cooled independently, and linked to each of the base stations by no greater than 40km of fiber optic cable.
Moving BBU processing to the cloud eliminates an entire base transmission system (BTS) equipment room from the base station (BS). It also completely abolishes the principal source of heat generation inside the BS, making it feasible for much, if not all, of the remaining equipment to be cooled passively — literally, by exposure to the open air. The configuration of that equipment could then be optimized, like the 5G trial transmitter shown above, constructed by Ericsson for Japan’s NTT DOCOMO. The goal for this optimization is to reduce a single site’s power consumption by over 75 percent.
What’s more, it takes less money to rent the site for a smaller base station than for a large one. Granted, China may have a unique concept of the real estate market compared to other countries. Nevertheless, China Mobile’s figures show that rental fees with C-RAN were reduced by over 71 percent, contributing to a total operational expenditure (OpEx) reduction for the entire base station site of 53 percent.

Keep in mind, though, that China Mobile’s figures pertained to deploying and maintaining 3G equipment, not 5G. But the new standards for transmission and network access, called 5G New Radio (5G NR), are being designed with C-RAN ideals in mind, so that the equipment never generates enough heat to trip that wire, requiring OpEx to effectively quadruple.
The new cloud at the new edge
It would appear a lot of the success of 5G rests upon this new class of cloud data centers, into which the functionality of today’s baseband units would move. As of now, there is still considerable uncertainty as to where this centralized RAN controller would reside. There are competing definitions.
Some have taken a good look at the emerging crop of edge data centers sprouting adjacent to today’s cell towers, and are suggesting that the new Service Oriented Core (SOC) could be distributed across those locations. Yet skeptics are wondering, why bother with the elimination of the BTS station in the first place, if the SOC would only put it back? Alternately, a separate SOC station could be established that services dozens of towers simultaneously. The problem there, obviously, is that such a station would be a full-fledged data center in itself, which would have real estate and cooling issues of its own.
Either option might be more palatable, some engineers believe, if the servers operating there could delegate computing infrastructure among internal operations and special customer services — edge computing services that could compete with cloud providers such as Amazon and Microsoft Azure, by leveraging much lower latency. The ability to do so is entirely dependent upon a concept called network slicing. This is the subdivision of physical infrastructure into virtual platforms, using a technique perfected by telecommunications companies called network functions virtualization (NFV).

The dicey subject of slicing
Exactly what routes these network slices would take through the infrastructure is completely up in the air. T-Mobile and others have suggested slices could divide classes of internal network functions — for instance, dividing eMBB from mMTC from URLLC. Others, such as the members of the Next Generation Mobile Networks Alliance (NGMN), suggest that slices could effectively partition networks in such a way (as suggested by the NGMN diagram above) that different classes of user equipment, utilizing their respective sets of radio access technologies (RAT), would perceive quite different infrastructure configurations, even though they’d be accessing resources from the same pools.
Another suggestion being made by some of the industry’s main customers, at 5G industry conferences, is that telcos offer the premium option of slicing their network by individual customer. This would give customers willing to invest heavily in edge computing services more direct access to the fiber optic fabric that supports the infrastructure, potentially giving a telco willing to provide such a service a competitive advantage over a colocation provider, even one with facilities adjacent to a “carrier hotel.”
Read also: Micro circuitry innovation needed to implement 5G
But depending upon whom one asks, slicing networks by customer may actually be impossible. There are diametrically split viewpoints on the subject of whether slicing could congregate telco functions and customer functions together on the same cloud. Some have suggested such a convergence is vitally necessary for 5G to fulfill the value proposition embodied in C-RAN. Architects of the cloud platforms seeking to play a central role in the SOC, such as OpenStack and CORD, argue that this convergence is already happening, and the whole point of the architecture in the first place.
AT&T has gone so far as to suggest the argument is moot and the discussion is actually closed: Both classes of functions have already been physically separated, not virtually sliced, in the 5G specifications, its engineers assert. In a January 2019 statement, the company said it has already begun deployments of what it calls Multi-access Edge Compute (MEC) services with select customers, in some cases using existing 4G LTE connectivity. “The data that runs through AT&T MEC,” the statement reads in part, “can be routed to their cloud or stay within an enterprise’s private environment to help increase security.”
But AT&T isn’t the “Bell System” any more — it doesn’t get the final say. Thus one of the most critical decisions in 5G architecture may end up being the result of trial and error.
However this issue gets resolved, the very fact that slicing must take place somehow, if only to virtually separate those functions that will not have already been physically separated, suggests that 5G will not be “a fully meshed world of wirelessly connected everything.” Security — the topic that always waits until the last moment — will ensure that certain things will remain strategically disconnected, for our own good.
The emergence of fixed wireless
Ericsson’s own forecasts of wireless connectivity have been known to fool people. In June 2017, its annual Mobility Report estimated that mobile data traffic would grow at an average compound annual growth rate of 42 percent through 2022, having grown eightfold by the end of that period. “By the end of the forecast period,” stated Ericsson, “more than 90 percent of mobile data traffic will come from smartphones.”
That forecast generated a truckload of headlines. A half-billion 5G mobile subscriptions are expected worldwide by 2022, reported ZDNet’s Corinne Reichert. Ericsson’s updated report, published last November, doubled that forecast number for 2023, adding that 5G access would reach one-fifth of the world’s population by the end of that year.

The keyword in the above paragraphs is “mobile.” Up to now, all the “Gs” have pertained to the wireless access technology we’ve historically perceived as synonymous with mobility. For 5G to be truly successful, Ericsson’s Koratala told us, it will need to open up access to a broader range of devices, many of which are actually not the least bit mobile.
The not-so-mobile proposition
“These connections are expected to be going into devices in factories, transportation, and the grid,” said Koratala. “So the range of applications means a huge diversification of performance and requirements for communication. Then there are some use cases that might be demanding a 5x improvement in latency, a 100x or 1000x data volume, as well as [extending] battery life. So when you look at that set of requirements, it’s very clear that it is not a single use case. It really becomes an enabler for a wide variety of use cases, that will have different requirements to be met to make them viable.”
The key mission of mMTC is to service wireless devices that don’t move. Its transmission scheme will be tuned for very high density — for situations like factory floors where thousands of individual mechanical elements are sending operational data, simultaneously, to an off-site location for instant analytics.

Viewed in this light, the prediction that nine-tenths of mobile data will be consumed by the largest class of mobile devices, seems about as spot-on as a forecast that rain will continue to be wet. What is completely unpredictable at this point is whether a fixed wireless use case will be competitive in an environment where wired broadband is also undergoing a revolution.
Exchanging yesterday’s new technology for today’s
You will hear from many sources that 5G is not about what anything is, but rather what it enables you to do. No, it isn’t. 5G is about the things in which the telecom industry, and to a growing extent the data center networking industry, must invest in order to produce the latest editions of platforms such as V2X and mMTC, so that it can start earning revenue from those services. 5G is all about what it is.
If you end up watching smoothly streaming 4K video on a new class of smartphone, allowing yourself to be ferried between cities in an otherwise unoccupied vehicle, or participate in a virtual, real-time football tournament with a few dozen goggle-wearers scattered throughout the planet, then you will be fulfilling the hopes of telco engineers who hope to make 5G viable. The truth is, none of these consumer technologies are the real reason 5G is being engineered. Indeed, they are the side benefits.
The big gamble
5G is a collective bargain between the telecommunications industry and society. To allow for anything close to evenly distributed coverage over a metropolitan area, the base stations containing the transmitters and receivers (the “cells”) must be smaller, much lower in power, and much greater in number than they are today. Essentially, the new cell towers must co-exist with the environment. An outdoor photograph taken in any direction will be just as likely to include a 5G tower as not. (The example above, provided by AT&T, includes three.)

It would not be unprecedented in history. We’ve borne telephone and electric poles through our neighborhoods and, not all that long ago, willingly installed TV aerials the size of kites on our chimneys. Some of us still use their old mounting posts for our satellite dishes. In exchange for the hopefully minor blemish on our landscapes that 5G may bring, many would wave a cheerful good-bye to dead spots.
All these things must happen, and in relatively quick succession, in order for telcos to afford the infrastructural overhaul they now have no choice but to make.

Callaway Chevy Silverado SC602 Signature Edition trounces Ram TRX in a drag race
American performance vehicle builder Callaway Cars has debuted its newest creation: The Chevy Silverado SC602 Signature Edition, now officially the best sleeper truck on the road. How fast? Hold your breath: This Chevy Silverado has trounced the mighty RAM TRX in a drag race. That’s saying a lot since Ram made it clear the TRX is “the quickest, fastest, and most powerful mass-produced truck in the world.”
But as it turns out, Callaway has other plans. The company has a long and cherished history of building quirky yet high-end performance cars like the C4 Corvette Sledgehammer and C7 Corvette AeroWagen. However, what we really love about the Silverado SC602 is the way it looks.
It may resemble a factory-stock Chevy Silverado from some angles, but there are telltale signs of the truck’s outstanding stoplight-to-stoplight ability. Like those 20 or 22-inch Callaway lightweight wheels, for instance, or the bevy of chrome Callaway exterior badging, including a bold CALLAWAY script on the carbon fiber front grille.
As with any Callaway vehicle, what matters most is hiding under the sheet metal. The SC602 starts life as a Chevrolet Silverado Trail Boss, RST, LTZ, or High Country with a standard 6.2-liter V8 motor and four-wheel drive. Next, Callway installs a GenThree Eaton TVS R2650 Supercharger with a TripleCooled intercooler. The blower offers 15-percent more displacement yet requiring 18-percent less power output.
It doesn’t stop there. The truck also gets a high-flow intake, low-restriction stainless steel dual outlet exhausts with quad exhaust tips, and a bespoke Callaway ECU with custom tuning. After all the dirty engine work is complete, the Callaway Silverado SC60’s blown V8 is now pumping out 602 horsepower and 560 pound-feet of torque.
But wait, the Ram TRX’s Hellcat V8 makes 702 horsepower and 650 pound-feet of torque, 100 more horses (and 90 more torques) than Callaway’s truck, so how did it trounce the Ram? Two words: weight and tires. The Silverado SC602 tips the scales at only 5,820 pounds (2640 kg), while the Ram TRX weighs around 7,080 (3,211 kg) pounds.
The result is nothing short of astonishing. The SC602 goes from zero to 60 mph in 4.3-seconds, zero to 100 mph in 9.80-seconds, and breaks the quarter-mile in 12.5-seconds @ 113 mph. Meanwhile, the Ram TRX goes from zero to 60 mph in 3.99-seconds, a bit quicker than the Chevy.
But the latter is faster from zero to 100 mph as the Ram needed 10.14 seconds to perform the deed, proof of the Callaway Silverado SC60’s mid to high-range pulling power. And yeah, those sticky performance tires were partly responsible for the Callaway’s drag strip prowess.
What’s more, the Silverado SC602 is 50-state emissions compliant and carries a 3-year/36,000-mile warranty to supplement Chevy’s bumper-to-bumper warranty. Other goodies include aluminum door sills, billet aluminum pedals, an Alcantara-covered horn cover, and ID plaques to let other people know you’re driving the genuine article.
How much? We have no idea. But you can get in touch with Callaway if you fancy the ultimate Ram-beating sleeper truck.

Ford reveals the custom 2021 Mustang Mach-E to be given away for charity
Ford has supported various charities for a long time, often donating customized automobiles to be auctioned off. Each year Ford offers a customized car for the AirVenture charity, and typically that car is a Ford Mustang of some sort with a big V8 engine under the hood. This year, the car Ford is donating to the charity is a different kind of Mustang.
Ford has revealed the customized electric 2021 Mustang Mach-E that will be auctioned off this year. The vehicle was built to honor the sacrifices of Women Air Force Service Pilots. The special Mach-E is inspired by the female volunteer pilots and the planes they flew during World War II.
Proceeds from the vehicle auction support the EAA initiative to provide young women and underserved youths more access to careers in the aviation industry. Ford notes that it has worked with AirVenture for more than two decades and has donated 12 custom aviation-themed performance vehicles so far, raising a total of more than $4 million. 2021 marks the first year Ford has donated an electric vehicle.
The custom Mach-E was designed by Ford and has a custom paint scheme with military badging inspired by the warplanes the volunteers flew. Women Air Force Service Pilots flew almost every type of military aircraft in World War II as they rolled off the factory floor after assembly. Ford put badges, including the US Army Air Force star on both sides, wings logos on the hood and fender, and No. 38 on the front fascia, rear bumper, and inside the cabin.
That number represents the 38 volunteers who died serving their country. Women Air Force Service Pilots are a group of American volunteers who transported warplanes to US Army bases worldwide to be used in combat. The female pilots flew more than 60 million miles during the war and weren’t recognized as active military personnel until 1977 when the pilots were granted retroactive military status.

In collaboration with Porsche Latin America, Porsche Mexico, and Porsche Exclusive Manufaktur, German automaker Porsche has built a custom 911 Turbo S in memory of the late, great Pedro Rodriguez. Rodriguez is the most successful Mexican racing driver of all time.
He walked away with 11 titles in the World Championship of Makes – now known as the World Endurance Championship – and helped Porsche capture the crown in 1970 and 1971 aboard a Porsche 917 KH in Gulf Oil livery. Rodriguez claimed two Formula Grand Prix wins, four wins in the 24 Hours of Daytona, and a victory at the 24 Hours of Le Mans before losing his life in 1971 at the Norising street circuit in Nuremberg, Germany.
Fifty years on after that fateful and deadly crash, Porsche is reliving the glory days with a custom 911 Turbo S ‘One of a Kind’ Pedro Rodriguez. The car debuted at a Sportscar Together Day event at the Centro Alto Rendimineto in Toluca, Mexico, where it drew oohs and ahhs with its custom Gulf attire.
Porsche claims the 911 Turbo S ‘One of a Kind’ Pedro Rodriguez is, well, genuinely one of a kind. “This configuration, with these specific details and equipment, has been locked in the Porsche configurator, as well as in the production system, so that this car is literally unrepeatable,” said Camilo San Martin, Director of Porsche Mexico.
Wearing the iconic Gulf Blue paint with single orange striping, it also has custom high-gloss black wheels, an aluminum center lock, and a black number 2 in a white circle graphic on the doors and front hood. Look closely at the B-pillar and you’ll find a silhouette of the 917 KH race car wearing the colors off the Mexican flag, complete with the name and signature of Pedro Rodriguez.
Other bespoke elements include unique carbon moldings on the lower door frames (which illuminate when the doors are open), Graphite Blue leather seats with orange stitching, and an engraved tribute of the eight races that Rodriguez won aboard the Porsche 917 KH under the rear spoiler.
Also included are a Gulf Blue key fob (with Rodriguez’s signature) and a luggage set wearing the same blue and orange colors. It still has a turbocharged 3.8-liter flat-six pumping out 640 horsepower and 590 pound-feet of torque with an eight-speed dual-clutch gearbox under the hood.
The Porsche 911 Turbo S Pedro Rodriguez will hit the auction block later this year. Porsche will donate the auction proceeds to various charities.
