BMW revisits its 8 Series

So why would BMW choose July 2 to release a retrospective on the 8 Series? Could it have something to do with the recent unveiling of the Pininfarina Gran Lusso Coupe concept, another sleek, B-pillarless V12 two-door, at this year's Villa d'Este? We have no idea, but the timing is likely coincidental.
This three-minute look at the 8 Series talks to Niels Hamann, who was smitten with the long-hooded coupe when it appeared in 1989 and finally bought one in 2004. Hamann also happens to be a project manager at BMW, and that came in handy when he wrote a book detailing every aspect of what was BMW's flagship for ten years but to the chagrin of many only managed one generation.
While we wait for the next clue about the Gran Lusso - 8 Series connection, check out the video below.

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.

BMW X4 M40i spotted testing in Germany

The stream of segment-busting BMW variants is showing no signs of letting up, and with the latest addition now upon us, questions have been circulating as to whether the Bavarian automaker would do an M version of the new X4 crossover. The jury may still be out on that proposition, but the latest intel suggests that, while a full-on X4 M may not be in the cards, a next-best-thing X4 M40i is in the works. And that appears to be what we're looking at in this fresh batch of spy shots.
Spotted for the first time undergoing testing in Germany, this X4 is tipped to be the next addition to the M Performance line that's already given us near-boiling models like the M135i and M235i on the one hand and the diesel-powered M550d, X5 M50d and X6 M50d on the other. Power in this case is tipped to come from the same 3.0-liter turbo six as the upcoming M2, producing between 360 and 380 horsepower.
Unlike the current top-of-that-specific-line X4 35i, which has two tailpipes on one side, this partially-camouflaged prototype has one pipe protruding from each corner of the rear bumper, but looks like it could easily accommodate twin pipes on both sides. Expect commensurate suspension, brake, rolling stock, aero and trim upgrades to come as part of the package, though they likely won't be quite as substantial as those applied to the X5 M and X6 M.
