Recharge Wrap-up: Venturi to break electric world record, app shows where bike lanes are needed

Electric automaker Venturi hopes to post a new electric land speed record this week, despite Bonneville Speed Week being cancelled. The VBB-3, developed with Ohio State University, is powered by two 1,500-hp electric motors. If the salt flats are sufficiently dry, the team hopes to set a new electric world speed record of over 600 kilometers per hour (373 mph), and possibly 700 kph (435 mph). The Venturi BB-2.5 set a record of 495 kph (307 mph) in 2010. Read more at Electric Autosport, and keep abreast of Venturi's progress at its Twitter account. A new app is trying to fix Wiesbaden, Germany's bike problem. A bike organization named the city the worst in the world for cycling. In response, a local group developed an app that uses crowdsourced routes to suggest where bike lanes and paths should go. The app tracks users routes as they ride, and maps them to show where the city could benefit from improving its infrastructure. The app and its results have the attention of government officials, too. See the video below, or read more at Fast Company. BMW has delivered the first i8s at the Pebble Beach Concours d'Elegance in California. The first customers include Roger Penske, Rick Hendrick and Tony Fadell (founder and CEO of Nest). The lucky new owners were also treated to a gourmet meal from Chef Thomas Keller, who was also among those to receive the i8 at the event. As mentioned, BMW also auctioned off a special edition i8 at Pebble Beach for $825,000, considerably more than the car's base MSRP of $135,700. Read more in the press release from BMW, below. Uber's Berlin ban has been suspended by a local court. The city banned the car-hailing app for failing to meet passenger safety standards. The court will now decide whether to uphold the ban or toss it out. This was the second time this year that Uber had been deemed unlawful in Berlin. Uber continued to operate throughout its ban, despite threats of fines. If upheld, Uber could be fined $34,000 for picking up a passenger. Read more at The New York Times.

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.

Alpina B4 coupe will be your subtle M4

We're big fans of Alpina here at Autoblog - the BMW tuner has created some seriously delicious products in the past, and recently tuned the diesel-powered 3 Series wagon to create the D3 Bi-Turbo. What we like most about Alpina is how the cars only look subtly more aggressive than stock, yet they pack a real wallop under the hood.
Take this B4 Coupe, recently spotted testing at the Nürburgring. It looks pretty tame compared to the normal 435i, the only visual additions being the Alpina-standard 21-spoke wheels, modified front lip and rear wing spoiler. But under the hood, Alpina is reportedly working on a tuned, twin-turbo straight-six that produces something like 410 horsepower. That means the B4 should be good for a 0-62 time of 4.2 seconds, with a top speed around 190 mph. Rear-wheel drive will be standard, though our spies suggest that Alpina could also use all-wheel drive here in the B4.
We have no doubt that the next BMW M4 will be super hot, but for those seeking a bit more stealth and exclusivity, this Alpina B4 certainly looks the business. Check it out in our gallery above.
