BMW i3s traction control tech going in all BMW, Mini cars

The BMW i3s is essentially a warmed-up version of the i3 electric car we all know and love. The performance boost isn't huge — just 14 horsepower and 15 pound-feet of torque — but it also gets a new suspension, wheels and tires as well as an improved traction control system. We found the car to benefit from all the updates when we drove it for our First Drive Review, but now BMW has offered up more details on just how the traction control system of the i3s helps make it better to drive. The company says it'll expand the technology to all future BMW and Mini models as well. The i3s's system is calibrated to help it to pull away quickly from a stop, making full use of the instantaneous torque offered by the electric motor. It also improves stability when accelerating out of corners, when using regenerative braking and, of course, when the road conditions are less than ideal. The results are palpable, and with the other improvements the i3s definitely feels stronger off the line, as we found on our drive. It's also about a half-second quicker to 60 miles per hour, at 6.8 seconds. The secret is in the response time of the stability control, which BMW claims is 50 times faster than the conventional system. This is made possible by moving the control process into the powertrain itself, rather than a remote unit. This reduces the signal path and, thus, the response time of the traction control system. BMW's Head of Chassis Development, Peter Langen, said of it, "With their high levels of torque and instantaneous responses to every movement of the accelerator, electric motors already make significantly higher demands on driving stability systems than conventional power units." While engineered to make the most of the electric motor, BMW says the shorter cycles of this traction control system show promise for internal combustion vehicles as well. As such, we'll begin to see the improved technology applied across the BMW and Mini lineups going forward. Related Video:

BMW i3 misses top Euro safety rating [w/videos]

The Euro NCAP just tested a recent batch of new cars including the 2014 BMW i3, and the EV Bimmer scored less-than-perfect results. Though not horrible, BMW's all-electric/range-extended i3 was given a four-star (out of five possible) crash rating due to concerns with front-occupant whiplash and side-impact protection.
Based on the crash results, the BMW provided suitable protection for occupants in the frontal, side barrier, pedestrian and child-seat tests, but the i3 was tripped up when it came to the more severe side pole test and the rear-impact test. The pole test showed protection to the chest of the test dummy was "weak," and the front seats only provided "marginal" protection against whiplash for front passengers. Scroll down to watch two videos released by the Euro NCAP of the i3 being tested.

Alpina B3 Bi-Turbo offers Europeans a pre-M3 performance 3er

Anyone that's spent some time behind the wheel of the Alpina B7 probably knows enough to understand what Americans are missing with this, newly launched Alpina B3 Bi-Turbo. We've got no lack of M models to choose from, it's true, but the Alpina touch offers a completely different driving character, with almost as much performance. A pity then that Alpina has no plans that we've heard of to bring this one across the pond.
Filling the gap between the current 3 Series offerings and the outgoing M3 (we're not likely to even see the new M3 and M4 until September's Frankfurt show, nor be able to buy one until after that), the B3 Bi-Turbo brings serious performance to the F30 3er. As the name indicates, two turbochargers are used to force-feed BMW's 3.0-liter inline-six engine, for a total output of 410 horsepower and 442 pound-feet of torque. That power offers a big jump from even the BMW 335i sedan, and will push the B3 to 62 miles per hour in just 4.2 seconds and on to a top speed of 190 miles per hour. Alpina's own sport suspension underpins the thing, while the power is modulated by way of a eight-speed automatic transmission.
The new B3 will be easily recognizable thanks to its "Classic" 20-inch, 20-spoke Alpina wheels, and a rather subtle, aero-enhancing body kit. No pricing has yet been announced, but you will find a host of additional information in the attached Alpina press release below.
