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's Connected Drive feature vulnerable to hackers

BMW is working to fix a cyber-security flaw that has left 2.2 million vehicles worldwide vulnerable to hackers. Cars equipped with the automaker's Connected Drive remote-services system are affected, according to the German Automobile Association (ADAC), which first discovered the problem. Researchers found they could lock and unlock car doors by mimicking mobile communications and sending phony signals to a SIM card installed in affected vehicles. An attack could be launched "within minutes" of accessing the system without the perpetrators leaving a trace, according to their report, in part because once they had gained access to the network, the communications were not secure. In response to the security gap, BMW says it has been upgrading software via over-the-air updates over the past week, so no visits to dealerships are needed to remedy the security hole. In fact, owners of affected cars may not have even noticed the updates taking place. The problem affects BMW, Rolls-Royce and MINI vehicles equipped with Connected Drive since 2010. Flaws were first reported to BMW last year by ADAC, which is the country's equivalent of AAA. ADAC says it withheld a public announcement until the car company could address the problem. While BMW has pushed the software patch to most affected vehicles, the organization said it's possible some at cars in the United States had not yet been updated. BMW did not respond to a request for comment Monday. In a written statement, the automaker said it knows of no real-world breaches. 2015 Off To Dubious Start The hack could raise the eyebrows of industry leaders: Cars are now the equivalent of mobile computers and cyber-security experts have been warning that the auto industry has been slow to close its security holes. BMW's breach marks the second time in 2015 that researchers have found a popular automotive feature with little or no security precautions. Last month, experts said a popular device made by Progressive Insurance that allows motorists to track their driving habits contained no security whatsoever. Like the Connected Drive smart-phone app, many automotive components and infotainment features were conceived and produced at a time when industry executives never considered the possibility someone might want to hack into them. But increased connectivity brings increased risk. Going forward, BMW says its Connected Drive features will now operate by using encrypted communications via the HTTPS protocol.
