2015 BMW M3 Sedan, M4 Coupe are officially revealed [w/video]

The new 3.0-liter inline-six makes 425 turbocharged horsepower from 5500 rpm all the way up to 7300 rpm.
BMW has announced the 2015 M3 Sedan and M4 Coupe, high-performance versions of the new 3 Series and 4 Series that launched this year. The new Ms have stirred controversy in a variety of ways, but one must remember that the M cars traditionally don't follow a specific mold.

2016 BMW 330e Plug-In Hybrid First Drive

Piecing together the i8 eco sports car taught BMW some valuable lessons, some of which you'll see in the next generation or two of the company's electrified mainstream cars. You won't have to wait that long for BMW to deliver on the key lesson, which can be seen right here in the 330e: make hybrids fun to drive and don't make people compromise on what they like. The 330e neatly sidesteps the traditional character-blanching entry ticket you get with hybrids by delivering almost as much torque as the 340i and a sprint time to 62 miles per hour of 6.1 seconds. For most people eco-conscious enough (especially in a time of cheap gas) to bother with plug-in hybrids, that's going to be quick enough. And so is the 140-mph top speed. It won't quite manage the precision of a normal 3 Series because it's 353 pounds heavier, but it's not far away. This 330e is (theoretically) capable of delivering 25 miles of electric-car range or ridiculous amount of range as a gasoline-electric hybrid. It will post a 44-gram CO2 emissions figure and officially deliver 1.9 liters/100km on the NEDC test cycle in Europe, which translates to 124 miles per gallon equivalent in the US, though it's unclear what the EPA-certified number would actually be. While punching in a straight line is always good, and sipping fuel like it's being rationed is nice, the key part to the 330e is that still handles like a 3 Series should every time you arrive at that one fun corner. It won't quite manage the precision of a normal 3 Series because it's 353 pounds heavier, but it's not far off. BMW has buried the 7.6-kWh lithium-ion battery pack beneath the cargo floor, while the electric motor resides up front, so the weight distribution moves from 50:50 to 49:51, leaving it a touch heavier in the back. Effectively, it's a 3 Series with the 320i's 2.0-liter, four-cylinder gasoline powertrain, the standard eight-speed automatic transmission, and an electric motor sandwiched in between to create a hybrid. The electric motor adds 87 hp to the gas engine's 181 horsepower to offer 248 hp of total power (yes, we know they don't directly add up, but that's the total output). While it has 74 pound-feet of continuous torque, the electric motor can overboost to 184 lb-ft when it needs to. Add that to the gas engine's 214 lb-ft and the car has a maximum of 310 lb-ft – 22 lb-ft shy of the 340i, without pumping out as many emissions.

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.
