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 2 Series Convertible will flip its lid for $38,850

For the most part, they look almost identical to their coupe versions, except that they now boast an electrically folding soft top.
BMW is dropping the top of the 2 Series in early 2015 in the US with convertible versions of the 228i and M235i. They'll make their world debut at the Paris Motor Show later this year and will show their faces on this side of the pond at the 2014 Los Angeles International Auto Show.

2016 BMW X1 packs more into its little footprint

BMW is rolling out the second-generation of its X1 crossover, promising a roomier interior, greater efficiency and more technology in a compact form. The 2016 BMW X1 clearly embodies more dynamic styling than the model it replaces, with a more upright form punctuated by a higher seating position as compared to its low-slung predecessor. Inside you'll find a fully redesigned cabin space with more room for both people and cargo, and a long list of features. A 6.5-inch dashboard display comes standard along with a seven-speaker audio system and cloth seats, but buyers can upgrade to an 8.8-inch monitor, a 12-speaker Harman Kardon system, and a number of leather upholstery options. Upgrade to the Premium Package and you get a larger panoramic moonroof than that offered on the outgoing model, along with adaptive LED headlights and a head-up display. The Drive Assistance Plus package throws in features like lane departure, automatic high-beams, frontal collision warning, pedestrian detection, active cruise control, and park assist. There'll be an M Sport package available later as well, offering sports seats, paddle shifters, and a retuned suspension. Though BMW will surely be offering an array of engine options in other markets, for the US it's offering the new X1 exclusively in xDrive28i spec. Its 2.0-liter turbo four drives 228 horsepower and 258 pound-feet of torque through an eight-speed automatic transmission to all four wheels for a 0-60 time of 6.3 seconds. That ought to help the Bavarian automaker move even more than the nearly 62,000 units of the X1 it's sold since its introduction here in 2012. Pricing for the new version of BMW's littlest crossover will be released closer to its arrival in showrooms in the Fall, but you don't need to wait that long to delve into the full details in the press release below and the high-resolution images in the gallery above. The All-New BMW X1: - Greatest interior roominess and versatility in its class - Highest power with reduced emissions - Commanding presence, robust proportions, dynamic lines - Innovative connectivity and groundbreaking BMW EfficientDynamics technology unparalleled in the segment Woodcliff Lake, N.J. – EMBARGO: June 2, 2015 – 6:00pm EDT/3:00pm PDT... Today, BMW announced the all-new BMW X1 Sports Activity Vehicle.
