2014 BMW 328d rated at 32/45 mpg

BMW still hasn't released official fuel economy numbers for its diesel-powered 2014 328d, but now, those mileage ratings have been posted on the EPA's FuelEconomy.gov website. As expected, the 328d is quite an efficient little machine, with the rear-wheel-drive sedan good for 32 miles per gallon in the city and 45 mpg highway. That even bests the 30/42 mpg of the smaller Volkswagen Jetta TDI.
The last time BMW offered a diesel 3 Series in our market, it was the six-cylinder 335d, which - while mighty quick and excellent to drive - was only offered as a rear-wheel-drive sedan and was rated at 23 mpg city and 36 mpg highway. For 2014, BMW will offer the 328d with optional xDrive all-wheel drive, though that reduces the fuel economy numbers to 31/43 mpg. Beyond that, the BMW will even sell you a 328d xDrive wagon, which nets the same 31/43 mpg rating, according to FuelEconomy.gov.
Look for the 2014 BMW 328d to hit dealerships this fall, and when it launches, it will be the only diesel offering in its class (until the next Mercedes-Benz C-Class arrives, anyway). Lexus and Infiniti will offer hybrid versions of the IS and Q50, respectively, but we've always had a taste for torque, and the 328d's 2.0-liter engine with 180 horsepower and 280 pound-feet of twist shouldn't disappoint.

BMW M4 spied in coupe and convertible form

From the sound of it, we'll have to wait until the Detroit Auto Show to see the production version of the BMW M4, but spy shots show the new hi-po BMW testing recently in both coupe and convertible form. Showing a lot more skin than recent spy shots, these M4 prototypes look very similar to the M4 Concept we saw at Pebble Beach.
Carryovers from the concept car include the funky mirrors, bulging hood and the slotted front fascia vents, but the rear fascia seems to be missing the added flair of the concept and, as expected, the carbon fiber front splitter and exhaust tips are also missing from these M4s. Like the current M3 Convertible, the drop-top version of the M4 will utilize a retractable hard top.

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.)
