The new Mercedes-Benz CLA Super Bowl spot

It takes a certain kind of chutzpah for a German company that supplied the Nazi war machine to use a track that features the line, “I rode a tank / Held a general's rank / When the Blitzkrieg raged / And the bodies stank.” Apparently, Mercedes-Benz has exactly that sort of chutzpah. The premise, of course, is that you don't have to sell your soul to afford the company's stylish new CLA. That for under 30 grand, you too can dance with Usher, be pulled into red-carpet photographs with Kate Upton, and compete in Formula 1 races.

New BMW M3 and M4 engine secrets laid bare

BMW's M division has lifted the veil of secrecy on the inline six-cylinder engine bound for its upcoming M3 sedan and new-to-the-range M4 coupe and convertible, revealing a potent twin-turbocharged 3.0-liter direct injection gasoline unit that produces an official 424 hp at 7,500 rpm and what officials describe as "significantly more than 369 lb-ft" of torque. The newly developed engine, known under the internal codename S55 B30, shares its 84.0 mm bore and 89.6 mm stroke with BMW's standard turbocharged 3.0-liter in-line six-cylinder direct-injection gasoline mill, the M55 used across the German car maker's lineup, endowing the aluminum block unit with an overall swept volume of 2,979 cc. This represents a sizeable 990 cc reduction on the engine BMW's M division's new unit replaces, the S65.
