BMW wants to expand DriveNow carsharing program to 25 new cities

Daimler's Car2go car-sharing service just announced that it will debut in Rome, its 26th global city. Now, BMW says it wants to expand its own carsharing program to, wait for it, 25 more cities. Coincidence? We think not. BMW is looking to bring its DriveNow carsharing program, with its Mini Coopers and 1 Series, to as many as 15 new cities in Europe as well as 10 in the US, Bloomberg News says, citing comments BMW executive Peter Schwarzenbauer made at the Geneva Motor Show last week. The service is now operational in Berlin, Hamburg, Cologne, Munich, Dusseldorf and San Francisco and serves about a quarter-million people. Of course, it's that last city, where DriveNow started operations in August 2012, that's been somewhat problematic. San Francisco has tough guidelines when it comes to where the cars can be parked, with so few public parking areas to choose from. DriveNow charges $39 for membership in San Francisco, then $12 for the first half hour of driving and 32 cents for each additional minute. DriveNow competes directly against Car2go, which charges around $25 to become a member and then 41 cents a minute to rent a Smart ForTwo.

Mercedes says it's tops in luxury sales for 2012, not BMW

It turns out that Mercedes-Benz North America has legitimate claim to being the top selling luxury nameplate in the US in 2012.
While sources such as Autodata had put BMW in the top spot, registration data from R.L. Polk shows that Mercedes customers registering new vehicles topped the Bavarian automaker in the most recent calendar year. Polk says Benz posted 274,123 registrations, compared with BMW's 268,498.
In terms of sales posted, BMW had bested Benz 281,460 to 274,134. But sales are recorded somewhat inconsistently from automaker to automaker. Some book the sales as soon as they are shipped from factory to dealer. There is perennial gamesmanship between the two German rivals, and the sales numbers suggest that BMW pushed out some extra sheetmetal to dealers in the last four weeks of the year.

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.
