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 gearing up for Sochi Olympics with bobsled documentary [w/video]

BMW might be a German brand, but that isn't keeping its US branch from helping out Team USA as the 22nd Winter Olympics gets set to kick off in Sochi, Russia next month. We last reported on BMW's partnership with Team USA's bobsled team in November of 2012, but with barely a month until the opening ceremony, it's about time we hear something new about the team's progress. And that's exactly what's going to happen when Driving on Ice airs this Sunday afternoon. The documentary charts the progress of the Team USA/BMW partnership to redesign the team's two-man bobsled for an event in which the USA hasn't captured gold in since 1936. And if you're concerned that this will be nothing more than a long advertisement for BMW, then you'll enjoy knowing that the program has more to do with the Team USA bobsledders than with the automaker. Even the trailer stars a number of team members and coaches, along with BMW DesignWorks USA's Michael Scully, lead designer on the program. There's a short preview embedded below, so if you just can't wait for next month's Olympics to kick off, you'll want to tune into NBC at 12:30 pm (Eastern time). Scroll down to watch the video preview and check out the full press release from BMW. BMW Slides into 2014 Winter Olympic Year with Announcement of U.S. Olympic Marketing Campaign, Bobsled Documentary. "Driving on Ice," a Film About BMW's Redesign of the Team USA Two-man Bobsled, to Air This Sunday on NBC. Woodcliff Lake, NJ – January 3, 2013... BMW of North America, the Official Mobility Partner of the United States Olympic Committee (USOC), today announced its U.S. Olympic marketing campaign for the Sochi 2014 Olympic Winter Games which includes a series of Olympic-themed advertisments, consumer and retail activations, social and digital media executions, and a national drive campaign to benefit Team USA. In addition, a documentary on BMW's complete redesign of the U.S. two-man bobsled entitled "Driving on Ice" will air this Sunday, Jan. 5 at 12:30 p.m. EST/11:30 a.m. CST on NBC. "Driving on Ice" chronicles BMW's collaboration with the USA Bobsled & Skeleton Federation (USBSF) to deliver a fleet of six new two-man bobsleds, applying the automaker's world-class design and engineering expertise to help Team USA chase its first Olympic gold medal in the event since 1936.

BMW X4 M40i caught production-ready

It seems like BMW is pretty committed to this whole X4 thing. Aside from the current xDrive28i and xDrive35i, we've captured a round of spy photos showing what our spy shooters tell us is a more dynamic M40i model.
The higher-performance hunchback follows in the footsteps of BMW's other sub-M cars like the M235i. In fact, much like the high-po 2 Series, the M40i is expected to make use of a 3.0-liter, turbocharged six-cylinder, developing 365 to 375 horsepower.
Aside from that, the rest of the X4 M40i fits the brief of other near-M models, with a more aggressive body kit, larger wheels, firmer suspension and brawnier brakes. Expect some mild tweaks inside, too, including sportier seats and an M-specific steering wheel.
