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.

Jay Leno gets pulled over while roaring in a Corvette Z06 convertible

No one is above the law, even if that person is a certain silver-haired auto enthusiast with a popular weekly video series about the cars in his garage. This week, Jay Leno experiences the 2015 Chevrolet Corvette Stingray Z06, but he also gets to have a meeting with some of California's Finest immediately after a high-speed blast. As opposed to the full-bore Z06 coupe with the seven-speed manual, Leno gets behind the wheel of the slightly heavier convertible version with the eight-speed auto. Being a droptop doesn't bother him too much, but Leno makes it obvious he wishes that he could be shifting for himself. Even if the auto is technically quicker, Leno says that swapping gears gives him something to do while driving. Of course, one of the major advantages of the convertible is the ability to listen to the Z06's thumping V8 unimpeded. With 650 horsepower and 650 pound-feet of torque from 6.2-liters of supercharged muscle, it already puts down impressive numbers, but the sound might just be the best part of all. Around town, the 'Vette is quiet enough to easily blend in with the rest of traffic. However, tip the throttle down and the valves in the exhaust open up to turn the engine into roaring monster. Be careful where you make this thing howl, though, because it's pretty easy for the police to take notice. The host finds that out the hard way in this week's episode of Jay Leno's Garage.

New 2016 Chevy Volt ad arrives in time for Tomorrowland

As summer approaches, so do the blockbusters. We've already seen Furious 7 and The Avengers: Age of Ultron, while Mad Max: Fury Road arrives this week. Next week's big debut is Disney's Tomorrowland, starring George Clooney, and not surprisingly, the advertising campaign is kicking into gear. Perhaps attempting to capitalize on the high-tech theme of the flick, Chevrolet has teamed up with Disney for the second-generation Volt's very first commercial appearance. As we reported previously, the Volt will star on the big screen when Tomorrowland hits theaters, and it will be accompanied by the EN-V Concept. Take a look at the Volt's Tomorrowland spot, up top.
