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.

AWD BMW M5 is headed our way

Remember the rumor about the BMW M5 going all-wheel drive? Well, there's definitely some truth there because these spy shots show BMW testing the Autobahn-storming sedan with the ability to spin the front and rear wheels. Our spy shooters grew suspicious when they saw this seemingly normal-looking M5 appearing to turn all four wheels during ice testing. They checked it out and snapped these shots underneath clearly showing power routed to the front axle. While this shows that the tech is at least being tested on a current-gen M5, all-wheel drive is probably not coming until the next 5 Series model, which is already being evaluated. The idea of power going to the front and rear axles for this sport sedan might polarize some hardcore brand fans as a break with tradition. However, the head of the M division thinks the change is a priority to actually put torque down effectively. The future vehicle is slated to get at least 600 horsepower and pack it into a lighter platform. Rear-drive M5 purists can take heart, though. The all-wheel-drive system would reportedly be an option, and it would be rear-biased to still let drivers hang the tail out, if the desire arises.

Corvette gets slidey with Britain's best performance cars

Autocar wants to find Britain's best driver's car, and it's challenging a murderers' row of some of the world's best performance vehicles to find out, including the latest Chevrolet Corvette Stingray. All of them were therefore assembled at the Castle Combe Circuit to find a winner.
If it wants to take the crown from this pack of mostly European competitors, the 'Vette has to beat some steep competition. Its challengers include monsters like the Ferrari 458 Speciale, Ariel Atom 3.5R and Jaguar F-Type Coupe. As a further hurdle for the winner to clear, Autocar also has last year's champ among the fighters - the Porsche 911 GT3.
Even if you're not at all interested in the C7, there's still something here for practically any fan of fast cars. The competitors include relative oddities among the pack like the Renault Mégane RS Trophy and Alfa Romeo 4C. Plus, Autocar has some well-positioned microphones that let you hear the Atom wailing like a banshee and the roar of the 458 Speciale. Check out the video to see which one of these all-stars takes home the award this year.
