Video shows Audi R18 'long tail' e-tron quattro's blistering Monza run

Audi has had a pretty solid run at the 24 Hours of Le Mans over the past decade, but we're glad they keep pushing the envelope. That's how they keep devising road-going spaceships like the staggeringly fast R18 e-tron quatto equipped with a “long tail” aerodynamic package. This quick video of the “long tail” hybrid testing at Monza gives us a preview of what we can expect at Spa next month -- and hints at what we'll see at Le Mans in June.

Infiniti Q50 [w/Gallery]

Infiniti has unveiled its new Q50 sports sedan at the 2013 North American International Auto Show (NAIAS). At the front, the signature ‘double arch' waved-mesh grille features chrome surrounds while a smooth character line rises from each side, flowing backwards along the sides. A prominent line beginning behind the narrow, tapering headlamps stretches towards the rear before smoothing out underneath the crescent-cut C-pillars that are similar to those seen on the Essence Concept.

BMW's new M engine needs a better voice

BMW's M division claims its new twin-turbocharged 3.0-liter inline six-cylinder engine is every bit as good -- if not better -- than the glorious, naturally aspirated 4.0-liter V8 powerplant it replaces in the new M3 sedan and M4 coupe. The figures are certainly impressive. They say it kicks out 424 hp and more than 25 percent extra torque, with what is described as significantly more than 369 lb-ft below 2,000 rpm.
