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 to unveil X4 in March

It's been about half a year since BMW unveiled the X4 concept in Shanghai. But if you've been waiting for news on when it will reach production, the latest intel indicates it'll be announced next March.
Just when in March? That's the strange part. Inautonews reports having been told by BMW that the new X4 will be announced on March 14. So, the Geneva Motor Show, then? Not quite: although that show will still be going on then, the doors open to journalists like us on March 4, not 14. So either someone has got some details mixed up, or BMW - for some reason - is planning on waiting until after Geneva to reveal the production X4.
Whenever it does, we'll be looking at a slantback version of the X3, much like BMW did with the X5 and X6, giving Bavaria a rival to the Range Rover Evoque and Porsche Macan.

Someone's willing to pay $16,000 for a hollow, non-working BMW i8

There is an unusual BMW i8 for sale on eBay right now. Unlike your average – and by that we mean "working" – i8, this one pretty much just sits there, looking pretty. See, the i8 in question is just a promotional body shell. It's fullsize and being sold (we think) by a legit BMW dealer (Laurel BMW of Westmont), so it's got strong ties to the real thing, but there's nothing inside. In fact, you can't open the doors or windows and the wheels don't move, unless you count the tiny rolling castors that are a part of the prop. There is no fancy plug-in hybrid powertrain – no powertrain of any sort, in fact – and it was "professionally crafted just for BMW dealers." The headlights do turn on, though, so that's something. What's most impressive, though, is that there are 50 bids for this non-working BMW. In fact, the bidding has climbed up to $16,000. For a car that can't fulfill its mission as a car, that's pretty impressive. Oh, and those bids have not yet hit the reserve price, so the dealer is obviously hoping it can get more money for this hollow BMW. The official base MSRP for a working i8 is $135,700. The first i8 delivered in the US, a special edition for Pebble Beach, just sold for $825,000.
