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 offering Track Handling Package for 2 Series

After getting a chance to drive the BMW M235i earlier this year, we mentioned our regret at not being able to sample the lighter and less powerful 228i Coupe. We'd like to have seen how close the latter could get to the former, noting that "there's a lot of room for upgrades with the $11,000 retail difference." BMW is closing that performance gap slightly, announcing that a Track Handling Package will join the options sheet for the 2015 228i Coupe.
The group bolts on Variable Sport Steering, Adaptive M Suspension and M Sport Brakes behind new 18-inch lightweight wheels wearing Michelin Pilot Super Sport tires. There's no change to the 240-horsepower four-cylinder, but a coupe so equipped should be able to do plenty more with the horses it has thanks to a faster steering rack, sharper handling due to additional sensors and a ten-millimeter drop in ride height, and larger brakes and discs.
BMW has used the New York Auto Show as a venue to introduce the new Track Handling Package, and it will roll onto showroom floors in July and pricing will be announced sometime between now and then. Takers can get it with both the six-speed manual and eight-speed Sport Automatic, see it in the high-res image gallery above, and read about it in the press release below.

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.
