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 recalling 40k+ motorcycles to replace rear wheel flange

A problem with the rear wheels on a wide array of its motorcycles has prompted BMW and the National Highway Traffic Safety Administration to issue a recall for 43,426 vehicles. In the affected units, the mounting flange on the rear wheel is at risk of cracking if the bolts are over-tightened. If that flange cracks, "the rear wheel may not remain secured to the motorcycle," which is kind of important considering there are only two wheels on a motorcycle to start with. The recall affects certain model-year 1200 and 1300 models – including the R1200GS, R1200RT, R1200GS, R1200R, R1200S, R1200ST, K1200S, K1200R, K1200R Sport, K1200GT, K1300S, K1300R and K1300GT – as well as the HP2 Megamoto, HP2 Enduro and HP2 Sport. Owners of the affects units can expect to head from the manufacturer to arrange having the aluminum flange replaced with a steel one.

In the affected motorcycles, the rear wheel mounting flange may crack if the rear wheel mounting bolts are over tightened. CONSEQUENCE: If the rear wheel mounting flange cracks, the mounting bolts may loosen and the rear wheel may not remain secured to the motorcycle, causing a loss of stability and increasing the risk of a crash. REMEDY: BMW will notify owners, and dealers will replace the existing aluminum rear wheel flange with a steel one, free of charge. The recall is expected to begin April 21, 2015. Owners may contact BMW customer service at 1-800-525-7417. NOTES: Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.

BMW i8 with 500+ horsepower in the cards?

While BMW makes plenty of machinery to keep enthusiasts interested, its most enticing models are often based on more ordinary ones. That's what made the arrival of the i8 so captivating, emerging as the first stand-alone BMW sports coupe since the M1. But if its dual purpose - trying its best to both embrace the earth and traverse it rapidly - somehow left you disappointed, the next development could prove to fix that.
According to Automobile, BMW is working on a more potent i8S model. The hardcore version of the hybrid sports car would offer more power and a stiffened chassis to make it that much more aggressive. The Bavarian automaker is reportedly still evaluating two potential powertrain options: The first would pair a 2.0-liter twin-turbo four-cylinder good for 320 horsepower to an electric motor with another 204 hp. The second would use a 3.0-liter straight six with 480 hp and an electric motor with 109 hp. Both would be mated to a nine-speed dual-clutch transmission and an integrated starter motor packing an extra 27 hp.
Either way, we'd be looking at a combined output well in excess of 500 horsepower - far more than the existing i8's 228-hp turbo three and 129-hp electric motor - dropping the 0-62 time down from 4.1 seconds to an estimated 3.5. Couple that to a more advanced carbon chassis, wider tires and other goodies, and the i8 would be transformed into a far more capable performance machine than it already is.
