Hamann BMW M6 Mirror can now cash the checks its body writes

Anyone remember the Hamann Mirror? Need a refresher? The Mirror is German tuning company Hamann's idea of a BMW M6. It was shown at the 2013 Frankfurt Motor Show as an M6 Gran Coupe, sporting a ridiculous paint job and some meaty, multi-spoke 21-inch wheels.
Consider this car the Mirror Mark 2. Based on the M6 Coupe, Hamann has applied a similar visual theme, using the same 21-inch wheels from 2013. Whereas the Gran Coupe rode around with a stock powertrain, though, there's been no such restraint with the two-door Mirror. A fine 620 horsepower is available from the 4.4-liter, biturbocharged V8, an increase of 60 horsepower. Torque is up as well, from 501 pound-feet to a whopping 560, meaning this M6 has speed to match its looks. Hamann claims the Mirror's newfound grunt allows it to hit 62 miles per hour faster than the standard M6 (we'd certainly hope so), although it won't mention a specific number.
The suspension, meanwhile, has been dropped 1.37 inches, or about a third of an inch lower than the Frankfurt Mirror. That drop is complemented by the Mirror's bodywork, including the exposed, carbon fiber hood and the flared fenders, which can now accommodate the enormous 305/25 rear rubber. Hamann has also paid some attention to the front and rear aerodynamics.

BMW looking to fix i3 acceleration problem uncovered by Consumer Reports

The BMW i3 has been hailed in some quarters as the future of electric mobility, what with its innovative carbon-fiber-reinforced plastic body and commitment to sustainable materials wherever possible. The modernist little hatch is even available with a 650cc two-cylinder gas engine with 34 horsepower to act as a range-extender for those who want it. However, that optional engine might have a drawback - at least for the moment.
Consumer Reports brought the problem to light when one of its drivers was behind the wheel of an i3 using the range-extender. When the driver attempted to pass another vehicle on a rolling, two-lane road, the BMW suddenly had no power to accelerate - a scary situation. CR started examining the car and found something pretty shocking: After driving at a constant speed for a while without any regenerative braking in range-extended mode, acceleration to 60 miles per hour plummeted from about 9 seconds normally to a staggering 27 to 40 seconds in their testing.
A BMW spokesperson told CR that it knows about the problem and has a fix coming next spring that also works on current models. The upgrade includes a state of charge indicator, a warning about loss of power and uses the car's navigation to boost the battery before driving on rolling terrain. It is not clear if the severe power deficiency will also eventually result in a recall.

Thermal imagery of BMW M4 DTM pit stop is red hot

A pit stop is a pit stop, right? The race car pulls in, the crew changes the tires, pumps in some fuel, maybe swaps out a busted body panel or squeegees the windshield, and off it goes for another heat. Only pit stops have become the focus of news lately for a number of reasons, whether it's because of mishaps (like the ones that prompted F1 to ban mid-race refueling), new time records (due largely to said ban) or interesting new ways to film the fast-paced action.
A few weeks ago we brought you footage of an IndyCar pit stop filmed from multiple angles courtesy of Google Glass. Now BMW has released a brief clip of one of its M4 DTM racers coming in for fresh rubber, all filmed by infrared camera. Its the kind of technology BMW uses to help optimize its German touring cars for competition, and now the Bavarian outfit has released some footage for fans to enjoy.
The resulting thermal imagery gives you an idea of how hot the car runs (and where the heat is emanating from), how warm they get the fresh rubber before they get it onto the car, and what kind of temperatures the pit crew is subjected to. Look closely enough in the 25-second video below and you'll even see the heat sputtering out of the exhaust pipes as the M4 downshifts into its pit box. (Just don't try adjusting your speakers, the clip is without audio.)
