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.

Lexus NX, BMW i3 to get Super Bowl commercials

At this point last year, we'd been getting news on automotive-focused Super Bowl commercials for more than two months. The teasers hadn't come out yet, but manufacturers lined up for the super-expensive spots were making their intentions known. This year? Almost nada, until this week. BMW has said it will air a 60-second spot promoting the i3 during the first quarter of the game, the Munich firm returning to The Big Game after a four-year absence. BMW says, "Big ideas like the BMW i3 take a little getting used to, and the creative idea surrounding our spot will play on this analogy." We say that pitching a tiny range-extended hatchback during the beer-iest American sports orgy of the year should make for some neat commentary afterward. Lexus is putting its new NX crossover in the second Super Bowl commercial it's ever aired, eschewing the glitter of celebrities and glamor for a straight-shooting spot and the tagline, "Be seen, be heard, make some noise." Joining those two are Kia, Mercedes-Benz, Nissan and Toyota. The six confirmed carmakers are down from eleven last year, when car spots made up a quarter of the total ad time. The price to do business for 30 seconds this year: reportedly around $4.5 million, up a stacks from last year's $4 million. You can watch the Lexus commercial in the video above, and beneath that, the BMW press release below has a bit more information on its effort. BMW to Advertise All-Electric BMW i3 during Super Bowl XLIX. The all-electric BMW i3 is featured in a 60-second spot during Super Bowl XLIX on Sunday, February 1, 2015. Woodcliff Lake, NJ – January 15, 2015... Today, BMW announced plans to feature the all-electric BMW i3 in a 60-second spot during Super Bowl XLIX on Sunday, February 1, 2015. After a 4-year hiatus, BMW will be returning to the big game with a commercial during the first quarter. "As one in three Americans will tune in to watch the Super Bowl, we are thrilled to use this platform to educate viewers on the importance of electric mobility," said Trudy Hardy, Vice President of Marketing, BMW of North America. "Big ideas like the BMW i3 take a little getting used to, and the creative idea surrounding our spot will play on this analogy." BMW i is BMW's forward-looking and sustainable brand dedicated to solving many of the mobility challenges faced by the world's most densely populated cities. The BMW i3 is the first of the BMW i vehicles constructed from the ground up primarily of carbon fiber.

Alpina introduces new B5 Biturbo with 600 horsepower

If the BMW M5 is not enough for you, Alpina created the new B5 Biturbo. Where the factory M5 packs 560 horsepower, the B5 has 600. But even more impressive is the B5 Biturbo bests the M5's 500 pound-feet of torque with 590 of its own. That beats the 15-hp boost from the M5's Competition Package and matches the power of the limited 30 Yahre edition - but with more torque. All that muscle and twist is produced by Alpina's own version of BMW's 4.4-liter twin-turbo V8, mated to an eight-speed automatic transmission instead of a seven-speed dual-clutch gearbox. The result is a 0-62 time quoted at 4.2 seconds, besting the M5 by a tenth. The top speed is also unlocked from 155 miles per hour to 204 – which may be entirely hypothetical for most of us, but could make all the difference for those who regularly commute along the Autobahn. Of course Alpina didn't tinker with the engine and leave it at that. It also customized the suspension, rolling stock, aero kit, and interior, and fitted a mechanical limited-slip differential built by Drexler Motor Sport. But perhaps the best part of all is that the Alpina B5 is also available as a wagon. That makes this modified Bimmer one of the best have-your-cake/eat-it-too propositions we could ever ask for.
