Chevrolet will preview electrified Silverado-like truck at CES 2021

After abandoning its fight against California's lawmakers, General Motors is shifting its electrification offensive into high gear. CEO Mary Barra will give the opening keynote address at the 2021 Consumer Electronics Show (CES), which will be held online, and Chevrolet will provide a peek at its electrified pickup during the event. Insiders familiar with the carmaker's plans told Bloomberg that Barra's address will highlight ways that electrification can improve the environment and society in general. General Motors president Mark Reuss will speak, too, and his remarks will be followed by a video that will highlight several future products, including what the sources referred to as "a plug-in Chevrolet pickup, some Cadillac models, and vehicles for other brands." These comments ask more questions than they answer, because plug-in means many things in this context. Chevrolet's electric Bolt is a plug-in vehicle, as is the upcoming GMC Hummer, but the plug-in hybrid Jeep Wrangler 4xe is one, too, and it's clearly not all-electric. It's often been assumed that Chevrolet's upcoming electrified truck will be electric, but it might arrive with a hybrid powertrain or a gasoline-powered range extender. Chevrolet could also follow Ford's lead and plant a stake in both the hybrid and the electric pickup segments. It's too early to tell if Chevrolet will unveil the same truck it previewed during a presentation earlier in 2020. Shown briefly, it wore a highly futuristic design that gave it a sleeker look than the current-generation Silverado. Cadillac's presentation promises to be interesting, because the company hinted it might abandon gasoline entirely by 2025, several years earlier than expected, even though its dealers aren't all on board with the shift. Going electric-only in about four years would force the brand to conduct a massive overhaul of its range. As of writing, there is not a single electric Cadillac in showrooms, but the Lyriq will arrive in late 2022 as a 2023 model. It's difficult to tell what's in store for other brands, but there are several cars that General Motors could show during CES. Buick doesn't sell an electric car in the United States yet, for example. Alternatively, GMC is working on an SUV variant of the Hummer, and it has started developing an electric truck. Going back to Chevrolet, our crystal ball tells us we'll see more of the 2022 Bolt EUV during the next edition of the tech show, too.

Is the skill of rev matching being lost to computers?

If the ability to drive a vehicle equipped with a manual gearbox is becoming a lost art, then the skill of being able to match revs on downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. The usefulness of rev matching in street driving is limited most of the time – aside from sounding cool and impressing your friends. But out on a race track or the occasional fast, windy road, its benefits are abundantly clear. While in motion, the engine speed and wheel speed of a vehicle with a manual transmission are kept in sync when the clutch is engaged (i.e. when the clutch pedal is not being pressed down). However, when changing gear, that mechanical link is severed briefly, and the synchronization between the motor and wheels is broken. When upshifting during acceleration, this isn't much of an issue, as there's typically not a huge disparity between engine speed and wheel speed as a car accelerates. Rev-matching downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. But when slowing down and downshifting – as you might do when approaching a corner at a high rate of speed – that gap of time caused by the disengagement of the clutch from the engine causes the revs to drop. Without bringing up the revs somehow to help the engine speed match the wheel speed in the gear you're about to use, you'll typically get a sudden jolt when re-engaging the clutch as physics brings everything back into sync. That jolt can be a big problem when you're moving along swiftly, causing instability or even a loss of traction, particularly in rear-wheel-drive cars. So the point of rev matching is to blip the throttle simultaneously as you downshift gears in order to bring the engine speed to a closer match with the wheel speed before you re-engage the clutch in that lower gear, in turn providing a much smoother downshift. When braking is thrown in, you get heel-toe downshifting, which involves some dexterity to use all three pedals at the same time with just two feet – clutch in, slow the car while revving, clutch out. However, even if you're aware of heel-toe technique and the basic elements of how to perform a rev match, perfecting it to the point of making it useful can be difficult.

Chevy trademark for E-Ray may signal Corvette hybrid or EV

A spy photographer and friend of Autoblog Chris Doane spotted this trademark filing with the US Patent and Trademark Office, and there's not much to it: Chevy is calling dibs on the "Corvette E-Ray" name, and that raises more questions than answers. Being obsessed with this industry is an Autoblog core value, and Corvette is perennially a big deal. It's also historically, and famously, resistant to change. So what's going on here? Unless it's a pure show car, it's unlikely the E-Ray will be a C7-based hybrid. The current Corvette is a tightly-packaged thing, and batteries are bulky. That makes a concept of some sort all the more likely, especially with the Detroit Auto Show coming up. Unconstrained by the packaging of the real-world Stingray, this E-Ray concept may be a pure EV, or a hybrid, of any configuration. GM has built mid-engined Corvette concept cars in the past, and maybe we'll see one again in a few weeks. A gutted C7 with a pure EV drivetrain is also a remote possibility, although less likely – the Stingray wasn't engineered with that in mind, and we think GM's too big to show off a hack-job at a major auto show. Not that it is a Corvette competitor, but don't forget that the Tesla Model S P85D and it's P90D successor have taken pure EV performance into the mainstream – the upper end of the mainstream, to be sure. It has been enough to draw industry performance players into the genre. Look at Aston Martin's production-possible RapidE concept, a pure EV, and the confirmed-for-production Porsche Mission E. We've heard rumblings in the past that Corvette may become a marque unto itself, spawning a variety of variants (including the hypothesized mid-engined production car – don't hold your breath). Perhaps the gas-powered C8, in whatever form it takes, will be complemented with a greener version. We'll try to dig up insider information about what the E-Ray will reveal itself to be, but rest assured that if it shows up at Detroit we'll bring you analysis of every inch of it.Related Video: Featured Gallery 2016 Chevy Corvette Z06 C7.R Edition View 9 Photos Tip: Chris Doane/Facebook Green Rumormill Detroit Auto Show Chevrolet Electric Future Vehicles Hybrid Performance corvette stingray
