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:

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 i8 named Autoblog's 2014 Technology of the Year [w/video]

The winner of Autoblog's 2014 Technology of the Year award was given this year for not just one technology, but for how a suite of technologies worked together to make one impressive vehicle. The BMW i8 was named the winner Wednesday night at the Belasco Theater in downtown Los Angeles, just outside the Los Angeles Auto Show. Autoblog's editorial staff agreed that the i8, which drew crowds of attention during our testing days, represents a future of driving that we can't wait to see happen. "I do believe that green vehicles solve a very fundamental problem, and if a car like the i8 can get a rich man with good knees (to get in and out of the car) to drive something with a plug instead of a 12-mpg sports car, then mission accomplished," says Sebastian Blanco, editor of AutoblogGreen and one of our judges. The panel reviewed nearly 50 qualified submissions from readers, editorial staff and industry, the panel of judges named the following as finalists: Dodge's SRT Performance Pages (read more here) The Subaru Eyesight forward collision warning system (read more here) The Performance Data Recorder in the 2015 Chevy Corvette (read more here) The 1.0-liter Ecoboost engine from Ford (read more here) Chrysler's 3.0-liter EcoDiesel V6 engine (read more here) Ultimately, we picked the car that excited us the most. The BMW i8 has a throaty exhaust note when accelerating. It's got carbon fiber, and a plug-in hybrid system that uses a small 1.5-liter three-cylinder engine and an electric motor. It has through-the-road all-wheel drive, and in Europe it'll come with laser beams for headlights. All that, and it's a massive eye catcher. People stop and stare when they see this car, for good reason. It's simply gorgeous. For a more in-depth look at our testing of the car, click here.
