BMW moves car-sharing program from San Francisco to Seattle

BMW is shifting more focus towards mobility services, which include car sharing and ride sharing. A new service, called ReachNow, will start out from Seattle and expand to other cities later. At first, the main competitors are ZipCar and Car2go, but ReachNow will also have to battle Uber. In a number of European cities, BMW already operates under the DriveNow program, which is getting revamped to better suit the US marketplace. Up until December, BMW made DriveNow available to San Francisco customers, but was forced to pull out due to parking space issues that are characteristic to SF. Perhaps Seattle makes things easier for BMW, though parking in any major metro area is sure to present some level of difficulty. BMW's idea is to offer pay-per-use pricing for driving a BMW 3-Series, BMW i3 electric vehicle or a Mini, which can be picked up from a street corner either by a 30-minute reservation or on-the-go, depending of the user's needs. Flexibility is key, whether you need a car for just a short while or for a longer weekend trip. The Seattle fleet will consist of 370 vehicles distributed across town. Later on, the service will expand to offer taxi-like ride sharing, to compete with Uber. As the glimmer of car ownership has faded in big cities, BMW wants to make sure it can still put people behind steering wheels or in the back seats. Luxury vehicle ride sharing is also on the cards, seemingly as a way to balance out the decidedly utilitarian choice of cars currently available.

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 D3 may be coming to Frankfurt with 350 hp, AWD

Rumors are swirling that Alpina, the tuning house that specializes in all things BMW, will followup its Geneva debut of the B3 Bi-Turbo with an oil-burning variant slated for debut at September's Frankfurt Motor Show. The news comes from Auto Zeitung, which reports that the second-generation D3 will be based off the Europe-only 335d.
This is a departure from the last D3, which had the four-cylinder turbo-diesel from the BMW 123d in a 3 Series body. The new model is expected to use a 3.0-liter, twin-turbocharged inline-six, which will generate 350 horsepower and 516 pound-feet of torque. That should scoot it to 62 miles per hour in under five seconds (likely while towing a tree stump). Both rear- and all-wheel drive should be available on the D3, and we imagine the thrill of this much power channeled through just the two rear wheels to be akin to skydiving sans parachute.
For our European friends that want an Alpina D3, but don't need more torque than any American full-size pickup, there may be plans to offer a four-cylinder variant that still delivers Alpina performance without a compromise in economy. We'll have more on the Alpina D3 when it debuts at the 2013 Frankfurt Motor Show.
