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:

Next-gen BMW X3 caught in the cold

The BMW X3 might be getting a bit long in the tooth, but fans of the sporty CUV can rest easy knowing that Munich hasn't forgotten about it. The third-generation crossover was caught squeezing in some end-of-season winter testing by our trusty spy photographers. According to our spies, the 2017 X3, code-named G01, will be underpinned by a new modular platform that promises more space in the cabin and better visibility out. Beyond that, the next X3 will get a range of B-series engines; expect four- and six-cylinder options, as well as a plug-in-hybrid option (eventually). Our spies also report that BMW will finally offer some more performance-oriented options, starting with an X3 M40i and eventually expanding into a X3 M. Beyond the oily bits, it looks like the X3's looks are set to evolve, growing slightly compared to its predecessor. BMW's trippy camouflage, though, prevents a closer analysis of the next-gen CUV's styling. Check out our full gallery of spy shots to see what's coming for the X3.

BMW i3 with range extender could arrive after HOV stickers run out in CA

We will weep for the BMW i3 REx owner with ticket #40,001 for California's green HOV stickers. While the standard-issue battery-electric i3 has been deemed eligible for the state's white stickers, which allow for owners to drive in HOV lanes solo, the proverbial jury of the California Air Resources Board (CARB) is still out on the BMW i3 REx, which will have a little-bitty range-extender on board, Transport Evolved says. The issue is that, while there is an unlimited number of white stickers for pure EVs such as the Nissan Leaf and Tesla Model S, the state has limited the number of green stickers, which grant solo-HOV access to plug-in hybrids and extended-range plug-ins, to 40,000. And with almost 29,000 green stickers given out as of the end of last year to cars such as the Chevrolet Volt and the Toyota Prius Plug In, they may run out within two months. The other key point is that the waiting list for the i3 with a range extender is running at about six months as of January, that could cause a bit of hand-wringing among folks looking to buy the REx. BMW said earlier this year that the extended-range version of the i3 would qualify for white stickers because the car is a so-called BEVx, meaning that its range-extender's full-tank range is less than the electric motor's single-charge range. BMW designed the i3 with a small range-extender tank of just 2.4 gallons, but the automaker estimated that California's green stickers wouldn't run out until the end of 2014.
