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 Concept X5 eDrive plug-in hybrid headed to Frankfurt

With six confirmed public debuts scheduled for the upcoming Frankfurt Motor Show, BMW is definitely going to have its hands full. While we've already driven models like the 4 Series and the i3, one of the more interesting introductions is a "concept" plug-in hybrid version of the new F15 BMW X5 called the BMW Concept X5 eDrive.
As the second concept to wear the eDrive name, this X5 combines a 95-horsepower electric motor with a turbocharged four-cylinder engine to balance performance and efficiency. On the green side of things, BMW says that the eDrive system allows the X5 to reach speeds of 75 miles per hour and a range of 19 miles (although we're guessing not at the same time) under electric power only, to go with fuel consumption of about 62 miles per gallon US (3.8 liters per 100 kilometers). For performance, this plug-in can still accelerate from 0-60 in under seven seconds, and drivers can select from three PHEV modes: one that operates the system automatically, an all-electric mode and a Save Battery mode to preserve the battery's current state of charge.
Aside from the obvious plug port on the left front fender, the X5 eDrive is differentiated from the 2014 X5 with slightly restyled front and rear fascias, subtle blue accents tying in with the BMW i line and lightweight, aero-tuned 21-inch alloy wheels. There is no definitive word on whether the Concept X5 eDrive will make it to production, but judging by BMW's recent commitment to plug-in vehicles, we wouldn't be surprised to see an X5 PHEV on the roads within the next couple of years. We'll see the Concept X5 in just a few weeks in Frankfurt, but until then, scroll down for the official press release.

A closer look at the 2015 BMW M3 and M4

It's fair to say we're going to miss the E92 BMW M3. Its high-revving V8, flame-styled looks and excellent driving character made it quite simply one of the best cars of the 2000s. Its replacements, the new M3 Sedan and M4 Coupe have a lot to live up to.
We still have a few months to wait until we can drive the new cars, but that doesn't mean we can't get excited in the meantime, learning everything we can. To find out, we sent west coast editor Michael Harley onto the Detroit Auto Show floor earlier this week to talk about the new M cars with BMW product manager Victor Leleu.
If you want a concise, but highly informative rundown of these new cars, look no further than this video. Leleu talks about the styling, weight savings and engines in a lot of detail, making this an interview M fans aren't going to want to miss. Scroll down for the full video.
