BMW M3, M4 let loose on the 'Ring

We just posted our first drive of the 2014 BMW 435i yesterday, but for those wanting even more power from this stylish coupe, help is on the way. From the sounds of it, BMW will be showing off a production-ready concept previewing the M4 next month at the Pebble Beach Concours d'Elegance, but until then, we have some new spy shots of the performance coupe being tested at the Nürburgring, along with its four-door counterpart, the M3.
Despite all the camouflage, it doesn't take much imagination to picture what both cars will look like, since we can clearly see the more aggressive front fascia and beefier brake setup. One interesting element we see on both cars is a double bubble roof that is almost certainly made from carbon fiber. Based on our report earlier, both the M4 Coupe and M3 Sedan are expected to debut at the 2014 Detroit Auto Show.

Preserving automotive history costs big bucks

$1.8 million is spent each year to maintain GM's fleet of 600 production and concept cars.
When at least two of the Detroit Three were on the verge of death a few years back, one of the tough questions that was asked of Ford, General Motors and Chrysler execs - outside of why execs were still taking private planes to meetings - was why each company maintained huge archives of old production and concept vehicles. GM, for example, had an 1,100-vehicle collection when talk of a federal bailout began.

Recharge Wrap-up: Range-extended EV taxis in London, 2016 Chevy Volt interior two years old

The first Metrocab range-extended EV taxis are operating on the streets of London. The cabs use a 12.2-kWh battery and two 50-kW motors, as well as a 1.0-liter gasoline range extender. Fuel economy is 98 MPGe on the ECE101 cycle, and total driving range is over 348 miles before needing to charge or refuel. Cabbies can expect to save GBP20 to GBP40 (about $30 to $60) per day on average. "The cash savings on fuel are significant, the ride and comfort outstanding, and my first customers are thrilled with the new cab," says the first operator of the new EV taxi, Preston Morris. "With its air suspension providing unrivaled comfort, panoramic glass roof for views of the city and silent powertrain, what's not to like?" Read more in the press release below. Chevrolet has had the interior design of the 2016 Volt finished for two years already, according to GM interior designer John McDougall. Beginning around 2010, GM received sketches from designers worldwide before narrowing it down to a handful of designs. Then the top three choices were molded from clay. The chosen theme was then refined for up to 18 months. "Every little thing you can imagine goes into that," says McDougall. "The glare angle from the windows, the placement of the controls, the placement of the seat. You have to create something that's beautiful and functional."

Vattenfall has announced a research project in partnership with BMW and Bosch to use retired EV batteries for stationary, grid-connected energy storage in Hamburg, Germany. Over 100 lithium-ion batteries from BMW i3 and ActiveE vehicles will make up a two-mWh storage unit for grid balancing, enough to power 30 four-person households for a week. The system is "compact enough to fit in a small building," says Bosch. Such storage systems are especially fit for storing and moving alternative forms of energy, which often fluctuate in supply more than electricity from a traditional power plant. Vattenhall will operate the storage unit for 10 years, with Bosch managing the batteries, during which time the three partners hope to learn more about battery applications and their performance over time.
