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:

Confident new Cadillac marketing boss ready to take on Tesla, BMW

When there's a former BMW executive heading Cadillac's efforts to boost sales of its only plug-in, it's a pretty safe guess that the marketing emphasis won't be on environmental friendliness and tree-hugging tendencies. The General Motors luxury brand has appointed ex-Bimmer executive Uwe Ellinghaus to be its marketing chief late last year, and the German-born Ellinghaus is now saying that he's targeting potential customers of Tesla Motors, in addition to BMW, for potential growth in sales of the Cadillac ELR extended-range plug-in. Appointed to Cadillac's head of marketing last November, Ellinghaus recently told Advertising Age that GM needs to highlight the Cadillac's looks and performance. He complimented Tesla for putting more emphasis on those attributes in the Model S than on its lack of emissions or lack of refueling costs (but Tesla hasn't shied away from highlighting the EV's savings). Ellinghaus says that trying to gear advertising "for people who are tree-huggers and green-wash an entire brand" won't be successful. You don't say. So far, the ELR hasn't made much of a dent in US car sales. Through May, Cadillac, which spent about $280 million on all of its US marketing last year, sold 293 units, whereas Tesla had been approaching the 11,000-unit figure for the Model S. With that in mind, Cadillac may be working on a sportier version of the ELR, as spy shots of a test vehicle from May revealed larger brakes and wheels.

2015 BMW X4 gets its small-screen debut

It's easy to dismiss the 2015 BMW X4. On one hand, the high-style crossover seems more like a boardroom decision than a practical one. In a world with the 3 Series, 4 Series, X3, 3 Series GT and 4 Series Gran Coupe, is BMW really being inundated with requests for a baby X6? Of course, when we finally got behind the wheel of the CUV for our First Drive, it proved rather entertaining, and certainly the X6's global sales success suggests that it's worth the relatively low-cost risk for the Bavarian automaker.
Now, it's the general public's chance to weigh in on the latest crossover Bimmer and vote with their dollars. The X4 is just hitting showrooms in the US, and BMW is beginning its marketing campaign for it with the slogan "Embrace the Unknown." The first TV ad shows off the CUV driving through the world's major cities as they undulate like the rolling ocean. A woman flatly says phrases starting with "Go," while a synth-heavy score plays underneath that wouldn't be out of place over the end credits in an '80s sci-fi movie.
Visually, it's actually kind of a cool ad and evokes some of the special effects from Inception. Focusing on an urban atmosphere is probably a good idea, too, because the percentage of X4s going offroad is likely to be in the low single digits, if that. Now, let's see if BMW buyers are willing to embrace the unknown of the X4. Scroll down to watch it for yourself.
