Upcoming new Alpina B7 teased

BMW does not make an M7. It never has, despite rumors, trademark filings, and the actual desires of the people that would build such a car. That means that while we're stuck waiting for BMW to see how foolish not building an M is, the most potent 7 Series you can get wears an Alpina badge on the nose. Meet the newest version of that car... sort of. BMW and Alpina haven't taken the wraps off the next B7 just yet, opting instead for an opera-accompanied teaser of the new car undergoing track testing. The car is lightly camouflaged – there's enough to make it clear it's a 7 Series, but not so undisguised as to reveal too much of the Alpina bodywork. There's a more aggressive bumper, a meaty rear spoiler, and sharper side sills, along with what are probably Alpina-specific wheels, but more precise details are hard to discern. What isn't difficult to pick out, though, is ear-tingling exhaust note. The last two Alpina B7s have built on the standard 7 Series' engine, and this new model likely won't be any different. That should mean a breathed upon 4.4-liter, twin-turbocharged V8 which goes well above the unfettled car's 445 horsepower and 480 pound-feet of torque. The extra power, along with the donor car's new lightweight carbon-fiber passenger cell, should make for tantalizing performance capabilities. The current 750i xDrive takes 4.3 seconds to make the sprint, and the B7 model that this new machine will replace hits 62 in 4.6. We'd expect the upcoming B7 will do better. The teaser from BMW and Alpina doesn't indicate when the new model will debut, but we'll eat our proverbial hat if it doesn't happen in Geneva. Related Video:

Alex Zanardi back in the driver's seat with BMW

If there's ever been an inspirational story in the pantheon of motor racing history, surely it's that of Alessandro Zanardi. The Italian driver worked his way up the motor racing ladder, making it into Formula One and winning two CART championships for Chip Ganassi Racing back before the series re-merged into IndyCars. Tragedy struck in 2001 when he lost both his legs in a crash at the Lausitzring in Germany, but rather than accept his fate, Alex pushed on. Fitted with prosthetic limbs, he learned to drive a racing car with hand controls and got back in the driver's seat.
Zanardi drove for BMW in the European Touring Car Championship and then in the World Touring Car Championship that replaced it, landing on the podium several times despite his physical disadvantage. He left racing in 2009 to train for the Paralympics, winning two gold medals in London, but Alex apparently couldn't shake the racing bug. BMW modified one of its M3 DTM racers with hand controls for him to test later that year. And now he's returning to motor racing full time.
BMW has just announced that Zanardi will be driving a Z4 GT3 in the Blancpain Sprint Series, the successor to the FIA GT Series and short-distance counterpart to the Blancpain Endurance Series. The car has been modified with the hand controls the Bavarian automaker's racing department fitted to the aforementioned M3 DTM and will be fielded by the ROAL Motorsport team with which Alex challenged for the European Touring Car Championship last decade.

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.
