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.

2015 BMW M3 Sedan, M4 Coupe are officially revealed [w/video]

The new 3.0-liter inline-six makes 425 turbocharged horsepower from 5500 rpm all the way up to 7300 rpm.
BMW has announced the 2015 M3 Sedan and M4 Coupe, high-performance versions of the new 3 Series and 4 Series that launched this year. The new Ms have stirred controversy in a variety of ways, but one must remember that the M cars traditionally don't follow a specific mold.

Car and Driver lists 10Best for 2013, same as it ever was

Forgive us for having the distinct feeling of déjà vu, but it certainly feels like we've been here before. By that we are referring Car and Driver and the announcement of its annual 10Best vehicles for 2013. To be sure, it's an impressive selection of cars that combine heart-pounding performance and frugal sensibilities, but it also represents something of a broken record on the part of C/D. We're not so sure that's a flaw, though, as the resulting list is tough to argue with.
Vehicles like the Ford Mustang, Porsche Boxster, and BMW 3 Series have maintained their high-horsepower spots on this list for several years now. Even on the more practical and nimble end, the Honda Accord, Honda Fit and Mazda Miata have not budged. These continued spots are even in light of redesigns for some vehicles such as the Accord, Boxster and 3 Series.
In fact, the only newcomer to the 10Best list this year are the Scion FR-S/Subaru BRZ twins, which knocked out the Cadillac CTS-V. We think it would have been a huge misstep to have excluded the FR-S/BRZ, even in light of the supercharged Caddy's lamentable departure from 10Best.
