2016 Chevrolet Volt Beauty-Roll

For those of you paying attention, we've really ramped up the old Autoblog video game these days. Our new series Car Club USA joins Translogic and The List, and there are more Daily Drivers and Short Cuts than ever. But sometimes, all you care about is the car. The Autoblog Beauty-Roll video series has one goal: bring you glossy video images of cars, and nothing but. We're collecting moving pictures of all the cars we test, inside and out. Each episode comes with a hit of engine sound – start-up and with a few revs – to round out the package. Set your resolution to max, kick it into full-screen, turn up the sound, and enjoy today's subject, the 2016 Chevrolet Volt. Oh, and if you'd like more Beauty-Roll, click here to see the back catalog.

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.

McLaren and Alonso will use Chevy engines at Indy 500

Fernando Alonso will have a Chevrolet engine in his McLaren when the double Formula One champion attempts to win next year's Indianapolis 500 in his second attempt, the British team announced on Tuesday. The 37-year-old Spaniard led 27 laps last year on his debut at The Brickyard in a Honda-powered Andretti Autosport car before retiring with an engine problem with 21 laps to go. The 2018 Indy 500 winner, Australian Will Power, won with Chevrolet-powered Team Penske last May. "Having Chevrolet power behind me means we're putting ourselves in the best possible position to compete at the front," said Alonso in a McLaren statement. The double Monaco Grand Prix winner, who won the Le Mans 24 Hours with Toyota this year, left Formula One at the end of the season last month and is targeting Indianapolis as the final part of the "Triple Crown of Motorsport": winning the Formula One championship (or Monaco), Le Mans and the Indy 500. The late Briton Graham Hill, also a two-times Formula One champion who died in 1975, is the only one to have done it, completing the triple in 1972.Reporting by Alan BaldwinRelated Video: Motorsports Chevrolet McLaren Racing Vehicles IndyCar
