This is the BMW Z4 GTE that will wear the Roundel in ALMS

The Speedweeks at Daytona International Speedway are a month of racing and reveals, with the season's metal going for the flag at races like the Rolex 24 at Daytona and other cars being introduced to the public. In the latter category is the BMW Z4 GTE (click the image above to enlarge) joining the American Le Mans Series GT class this year with BMW Team RLL (Rahal, Letterman and Lanigan). This machine replaces the M3 GT that completed four years of service and won the class title in 2010 and 2011. Naturally, the team is tempering expectations for the Z4 GTE by repeating the fact that it sees this season as a development year.
BMW Team RLL drivers for its two cars will be Bill Auberlen and series rookie Maxime Martin in the No. 55, aided by Jörg Müller for the endurance races at Sebring and Road Atlanta. The No. 56 car gets Dirk Müller on a full-time basis, Joey Hand when he's not competing in the DTM series, and John Edwards when Hand isn't available. Uwe Alzen will help out with driving duties in the No. 56 at endurance races.

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 i3 officially gets EPA-rated 81-mile range, delivered to first US customer

It's official. The first U.S. BMW i3 customer is now happily zipping along somewhere in his new car. Or possibly staring lovingly at it in his garage – we're not sure which. That man, Tufts University professor and electric vehicle aficionado Charles Rabie, was handed the keys at the BMW of Boston dealership earlier today, thus beginning a flood of upcoming deliveries from the pool of hundreds currently awaiting for their owners at the Port Jersey Vehicle Distribution Center in Jersey City, NJ. And now, when Mr. Rabie sets off in his spiffy electric Bimmer, he'll know exactly how far the EPA thinks he can go on a full charge of its 22-kWh battery. Speaking with Dave Buchko from BMW Corporate Communications, we learned the government agency has given the i3 an official range rating of 81 miles. Efficiency-wise, that breaks down to 138 MPGe city, 111 hwy, and 124 combined for the city car. Of course, we don't expect the good professor to experience any difficulties dealing with the sub-100 mile range. As a former BMW ActiveE driver, he's had plenty of opportunity to become accustomed to the foibles (and advantages) of piloting a battery-powered vehicle.

BMW Delivers First All-Electric i3 in the U.S. Tufts University professor of practice Charles Rabie to receive the first U.S. BMW i3. Woodcliff Lake, NJ – May 2, 2014... Today, BMW delivered the first all-electric BMW i3 in the U.S. to Boston resident and Tufts University professor of practice Charles Rabie at the BMW of Boston dealership. Hundreds of BMW i3 vehicles are currently at U.S. facilities and ready to be delivered to customers nationwide, ushering in a new era of electromobility. Rabie is an electric vehicle advocate and has been driving the BMW ActiveE since 2012. Also among this first group set to receive a BMW i3 is Los Angeles-based former E! Entertainment leading correspondent Ashlan Gorse Cousteau, married to renowned documentary filmmaker and environmentalist Philippe Cousteau, grandson of Jacques Cousteau. "Today marks a big day at BMW of North America - What started out as a dream for an innovative sustainable vehicle under the BMW i brand can now be found on streets across the U.S.," said Ludwig Willisch, President & CEO, BMW of North America. The BMW i3 is the first of the BMW i vehicles constructed from the ground up primarily of carbon fiber to enter the U.S. market.
