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:

As BMW i3 US launch nears, more details discovered

Think of the BMW i3's gas-powered range-extender as akin to driving around with a middle linebacker in the back seat. Except that football player will have a hard time pushing the car 60 miles or so once the battery runs out. Thankfully, he won't prevent you from getting a nifty tax credit either, according to BMWBlog, which isn't affiliated with the company. The i3's front storage compartment is not watertight. Here in the US, where the i3 will be available in short order, BMW will offer an optional i3 plug-in vehicle with a range extender that will have a 1.9-gallon capacity gas tank. That sounds a good deal smaller than the 2.4-gallon tank used in Europe, but the two are actually the same, the US tank is simply limited to the smaller size, Dave Buchko, from BMW's product and technology communications department, told AutoblogGreen. The complete range extender system – including the tank, the engine, and all related hardware – adds about 265 pounds to the 2,634-pound curb weight of the i3 EV and the extra weight in turn adds about a second to the EV's 0-to-60 time of seven seconds flat. Adding the range-extender won't make the US government take any longer to dole out a $7,500 tax credit for the i3, though. We also learned that the i3's front storage compartment is not watertight since it is only meant to hold the mobility kit and the 110-volt charging cord. BMW recently increased its production of the i3 at its German factory from around 70 units a day to about 100 due to better-than-expected demand.

Mini JCW Paceman vs. BMW M135i in family faceoff

Over the last year, we've had the chance to drive two of the most exciting hatchbacks in the BMW family - the BMW M135i and the Mini Paceman John Cooper Works - but Autocar has managed to get the two corporate cousins together for a head-to-head comparison. Just like our initial impressions of the Paceman JCW, Autocar has little to complain about this new 215-horsepower hatchback... until it begins to factor in the faster, better-mannered and similarly priced M135i.
Despite laying down an extra 100 hp and delivering a 0-60 time that is almost two seconds quicker, the M135i carries the same price tag of 29,535 pounds in the UK; US pricing for the Paceman starts at $36,200, while it still isn't even clear if the US will be getting the M135i. Even more surprising is the fact that the Paceman falls short of the M135i in regards to rear seat and cargo volume, and just barely squeaks out a win in the fuel economy department. Scroll down to watch the BMW versus Mini hot hatch battle.
