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.

BMW 4 Series configurator comes online

The best money in the world might be configurator money - you never run out of it and you can never spend it the wrong way. We hope you're ready to dip into your configurator savings account, because it's time to start speccing out the 2014 BMW 4 Series, the coupe having just arrived in the virtual world.
There are four possible opening gambits: the 428i for $40,500, the 428i xDrive for $42,500, the 435i for $46,000 or the 435i xDrive for $48,000. After you've chosen your first move, there are three trim options: the $1,400 Luxury Line that features lots of chrome and wood (shown), the $1,700 Sport Line that adds lots of gloss black and contrasting trim color and stitching, or the $3,100 M Sport that offers the M Estoril Blue hue and lots of M-division specific accessories.
Starting with the 435i xDrive and M Sport, we then added items like the 19-inch wheels ($900), the Dynamic Handling Package ($1,000), Cold Weather Package ($700), Premium Package ($2,200), Tech Package ($3,150) and the Lighting Package ($1,900) on top of any other box we could check. The total, after the $925 destination and handling charge: $66,749.

Watch BMW 3 Series drift in Scotland

Drifting is inherently connected with Japan largely because the sport originally hails from there. That's why many of the traditionally popular drifting machines are from Toyota, Nissan, and Mazda. However, as long as the rear wheels can spin, you can slide it, no matter where a vehicle is from. For a new video, Xcar discovers a grassroots contingent in Scotland that specializes in smoking the tires of the BMW 3 Series. These guys aren't running the hugely expensive machines that you see in top events, but they definitely don't lack for passion to get a car sideways. One guy in the video runs an absolutely insane-looking Nissan-powered E36 3 Series convertible. Another competes in an E30 station wagon with a Toyota engine. Watching these unconventional drifters out on the track is a cool experience. Clearly, these folks are using what's around them to fulfill their need for speed, and they look like they're having a ton of fun doing it.
