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 Bolt-based prototype may be a Buick EV for China

Late last spring, we got a look at a GM prototype that was clearly based on the Chevy Bolt EV, but with updated styling. It seemed like it could be a more crossover-styled Bolt, given the recently trademarked name of EUV. Now we get another look at the prototype, but the bodywork seems less suggestive of a Chevy, and more of a Buick. This vehicle definitely still appears to be based on the Bolt, rather than on another small GM platform. In the photos of it next to the current model, the size, wheelbase and profile are extremely similar. There are differences, though. The nose isn't as sloped or as rounded, and the rear window kicks up a little earlier. The biggest changes are in the front and rear fascias, and it's here that we see hints of Buick. There are prominent air inlets on each side of the front bumper that give the car a more aggressive look. The headlights still have a fairly rounded, organic look, but with little extensions like fangs underneath. The styled running-light section, rounded shape and the smoked lenses seem very Buick-like. The grille features a large badge that doesn't fit the shape of a bow-tie, and is more that of a round logo like Buick's. Around at the back, the full-width taillights stand out, and in the middle there is obviously a round badge, again like a Buick. The wide taillights would also be a natural evolution of Buick's current light design language that uses somewhat wide and thin lights. The rear bumper has been redesigned with new lower taillights. Now that we've established that this seems very much like a Buick, we don't think we'll see this particular version offered here with the badge. This is more likely a Buick version of the Bolt for the Chinese market, where the brand is associated with luxury and has been the spearhead for GM's electric and hybrid models. In fact, the Chevy Volt hybrid was sold there as the Buick Velite 5, which was part of a family of a electrified Velite models. This would probably also carry a Velite badge as well. While we might not see this specific Buick variant, we probably will see it offered as a Chevy in some form. With its more aggressive, crossover shape, it could be the rumored EUV model. Or it could be just a refresh of the current Bolt, since the model has been largely unchanged since its introduction for the 2017 model year. And extrapolating from this prototype, we can see how the headlights could be tweaked to tie into those air scoops as on the Suburban and Silverado.

'Tomorrowland' movie will advertise Chevy Volt, E-NVs

Before the 2016 Chevrolet Volt arrives at dealerships, it's going to come to a cineplex near you. The next-generation hybrid and the EN-V electric networked vehicle concept will play bit parts in the background of the upcoming Disney movie Tomorrowland starring George Clooney and Britt Robertson. Chevrolet will run digital and television ads around the movie's opening, which is May 22 in the US. The Bowtie and Disney tie-up is another in their years-long collaboration, going back to the revamped Test Track that opened at Epcot Center in 2012, and Chevolet is also the official vehicle of Shanghai Disney. The press release below has more on the movie and the Volt, the movie trailer is above – there's no Volt in it, but there is a late-model Buick. Chevrolet and Disney See Possibilities in 'Tomorrowland' Film to help kick off marketing efforts for next-generation Chevrolet Volt DETROIT, 2015-03-26 – At their core, Disney and Chevrolet are entities of optimism, believing that with a little ingenuity, anything is possible. They will come together in the new Disney film "Tomorrowland" to imagine the possibilities. The all-new 2016 Chevrolet Volt and EN-V concepts appear in the backdrops of the present day and Tomorrowland. The film's U.S. debut is May 22. In Disney's riveting mystery adventure "Tomorrowland," a jaded scientist and an optimistic teen embark on a danger-filled mission to unearth the secrets of an enigmatic place somewhere in time and space. "Tomorrowland is a place where nothing is impossible, which is something that Chevrolet believes can exist in the here and now," said Tim Mahoney, vice president, Global Chevrolet. "The Chevrolet spirit reflects the hopes and possibilities of tomorrow in real instruments of change for today like the next-generation Chevrolet Volt." The first marketing efforts for the 2016 Chevrolet Volt will be tied to Tomorrowland. A television spot and digital advertising will debut in early May. The all-new Volt is an electric car with extended range, showcasing a sleeker, sportier design that offers 50 miles of EV range, greater efficiency and stronger acceleration. The Volt's new, efficient propulsion system will offer an estimated total driving range of more than 400 miles. With regular charging, owners can expect to average more than 1,000 miles between gas fill-ups. Chevrolet and Disney have a long history of collaboration around the globe.
