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 profit of $2.7B is down as automaker invests to keep luxury lead

Despite selling 6.6-percent more vehicles - a record by volume - and posting higher revenues in the second quarter of 2013, BMW Group's profit of 2.07 million euros ($2.75 billion) is down 8.8 percent from last year. Investments in new technology (e.g. the new i3) and personnel, in addition to a competitive market, are to blame, BMW states. But the automaker remains committed to its fiscal targets for 2013, which, Chairman of the Board of Management of BMW AG, Norbert Reithofer, says will be "on a similar scale to 2012."
The BMW brand's sales performance in the first half of the year, which increased by 7.7 percent to 804,258 vehicles delivered, was good enough for it to maintain its lead in the luxury market, narrowly beating Audi, which delivered 780,510 vehicles, Automotive News reports. Mercedes-Benz delivered 694,433 vehicles to cement third place.

Official pics of BMW M235i surface ahead of coupe's debut

BMW isn't supposed to debut the 2 Series until tomorrow, according to Carscoops, but that hasn't stopped these photos of the 1 Series Coupe replacement from leaking onto the web. First picked up by a BMW 2 Series enthusiast site, the photos eventually found their way around the web, and complement the spy images we showed you of the uncovered 2 Series from almost six months ago.
This particular car is the M235i, and will serve as the range-topping 2 Series. As the number "35" is affixed to this car's tail, there's no question that the engine powering this example is BMW's turbocharged, 3.0-liter six-cylinder. As we reported earlier this month, power for the M235i should sit around 320 horsepower, blessing the 3,240-pound coupe with a 4.8-second sprint to 60 miles per hour when equipped with an eight-speed automatic (a six-speed manual is also available, but drops the time down to an even five seconds).
While this isn't a full-bore M car like the 1 Series M Coupe, it has been touched by the company's in-house tuning division, which means it sports a racier body kit, blacked out grilles and M-labeled interior items, like the steering wheel.
