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:

2015 BMW 4 Series Gran Coupe might be a better 3 Series sedan

At BMW, there really is something for everyone these days. Just take a look at the massive 3 Series/4 Series range - you can have a sedan, coupe, convertible, wagon, or funky-backed Gran Turismo. And now, with the introduction of the 2015 4 Series Gran Coupe, you can have another seda... err, hatchback, actually. But perhaps, a better one.
Compared to the 3 Series sedan, the 4 Series Gran Coupe is both longer and wider by about half an inch, but is shorter in overall height by an inch and a half. Honestly, to our eyes, it looks a little better than the 3 Series, too, what with its longer roofline, more sculpted rear haunches and lower stance. Full interior volume specs for the 4GC aren't available as of this writing, but we expect them to be roughly the same as the 3 Series, perhaps with a small decrease in headroom and rear legroom. Trunk space, at 17 cubic feet, matches the 3 Series sedan, and because the 4GC actually uses a hatchback design, it should be easier to access.
Powertrains are completely carryover from the rest of the 3/4 Series range. The 428i uses BMW's well-liked 2.0-liter turbocharged inline-four with 240 horsepower and 255 pound-feet of torque, and the 435i is fitted with the company's 3.0-liter turbo-six, good for 300 hp and 300 lb-ft. An eight-speed automatic is the only transmission available in the US with either model and rear-wheel drive is standard. Only the 428i can be had with BMW's xDrive all-wheel-drive system, and interestingly, the 428i Gran Coupe is actually expected to be more fuel-efficient than its 3 Series sedan counterpart. The GC is estimated to return 23/35 miles per gallon city/highway, compared to the 23/33 mpg in the 328i sedan. The 435i Gran Coupe should achieve the same 22/32 mpg ratings as the 335i sedan.

8 automakers, 15 utilities collaborate on open smart-charging for EVs

We're going to lead with General Motors here. GM is one of eight automakers working with 15 utilities and the Electric Power Research Institute (EPRI) at developing a "smart" plug-in vehicle charging system. Why did we start with GM? Because it's the first automaker whose press release we read that mentioned the other seven automakers. Points for sharing. For the record, the collaboration also includes BMW, Toyota, Mercedes-Benz, Honda, Chrysler, Mitsubishi and Ford. The utilities include DTE Energy, Duke Energy, Southern California Edison and Pacific Gas & Electric. The idea is to develop a so-called "demand charging" system in which an integrated system lets the plug-ins and utilities communicate with each other so that vehicle charging is cut back at peak hours, when energy is most expensive, and ramped up when the rates drop. Such entities say there's a sense of urgency to develop such a system because the number of plug-in vehicles on US roads totals more than 225,000 today and is climbing steadily. There's a lot of technology involved, obviously, but the goal is to have an open platform that's compatible with virtually any automaker's plug-in vehicle. No timeframe was disclosed for when such a system could go live but you can find a press release from EPRI below. EPRI, Utilities, Auto Manufacturers to Create an Open Grid Integration Platform for Plug-in Electric Vehicles PALO ALTO, Calif. (July 29, 2014) – The Electric Power Research Institute, 8 automakers and 15 utilities are working to develop and demonstrate an open platform that would integrate plug-in electric vehicles (PEV) with smart grid technologies enabling utilities to support PEV charging regardless of location. The platform will allow manufacturers to offer a customer-friendly interface through which PEV drivers can more easily participate in utility PEV programs, such as rates for off-peak or nighttime charging. The portal for the system would be a utility's communications system and an electric vehicle's telematics system. As the electric grid evolves with smarter functionality, electric vehicles can serve as a distributed energy resource to support grid reliability, stability and efficiency. With more than 225,000 plug-in vehicles on U.S. roads -- and their numbers growing -- they are likely to play a significant role in electricity demand side management.
