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:

Recharge Wrap Up: VW's Last Mile Surfer, Apple's BMW i3

Volkswagen has unveiled its Last Mile Surfer. This little electric scooter – it folds up small enough to fit in the trunk and weighs just 24 pounds – will go on sale next year for around 1,000 euros ($1,100 US), according to VW chairman Martin Winterkorn, as reported by Autocar. Of course, we're wondering why you'd need to pay that much money to avoid walking a mile, but maybe we just haven't walked that far in an interested buyer's shoes. See more at Autocar. Did Apple want to use the BMW i3 as the basis for its own electric car? That's the word from the German magazine Manager, which says that Apple and BMW were talking about using the i3 shell for the plug-in iCar (or whatever) started last fall but are no longer actively taking place, but the two organizations have not totally closed off communication. Read more at Manager or at Green Car Reports. BMW is continuing its efforts to connect your car to your phone in interesting ways with the new EnLighten app. The idea here is to let your phone act as a bridge between alerts about traffic signals and the car, so that notifications can be displayed in the dash instead of on your phone. That should keep more eyes on the road and let drivers minimize those races to the next red light, which will save fuel. At least, it will do so in cities that broadcast that sort of signal information. Read more in the press release below. Traffic City Info Makes Driving in Cities Easier than Ever Woodcliff Lake, N.J. – July 27, 2015... The BMW Group announced today that it is the first manufacturer to bring the EnLighten App, by Connected Signals, into the car. Drivers of BMW Vehicles with iOS Devices will be able to see traffic signal data on the vehicle's display in real time. The EnLighten app makes driving in cities easier by helping the driver anticipate traffic signal changes, which can increase safety and help save fuel by avoiding unnecessary acceleration. The EnLighten app shows the current status of the traffic light in front of the car in real time as well as a countdown to when the signal will change. Based on the current vehicle position, as well as its speed, the EnLighten app offers a recommendation about whether or not to stop for the traffic light or proceed through. An audio alert notifies the driver about a pending change in the signal they are approaching.

Petrolicious reconnects with the BMW M coupe

With the look of a clown shoe on wheels, the BMW M Coupe was a product of using what was around to create something great. Starting with the Z3 convertible, BMW's engineering team added a bulbous roof to improve rigidity, and for the M version, it dropped in the inline six from the contemporary M3. While the result wasn't a beauty queen, the car more than made up for any aesthetic complaints in driving pleasure. Petrolicious talks to owner Alex McCulloch about just what makes the tiny three-door so special in its latest video. With a fairly short wheelbase, plenty of power, and a rear suspension from the E30-chassis BMW 3 Series, the M Coupe can be a quite handful at the limit. "I used to say it wanted to kill me, but now we've reached an agreement where it's not quite as murderous," McCulloch says. He's eventually found that the only real way to exploit the coupe to its fullest is on the track, where he competes in time trials. To get lap times as low as possible, the BMW now wears quite a few mods, but McCulloch says that it's all reversible. Figure out what competitive hang gliding has to do with driving in this clip from Petrolicious. Related Video:
