Mercedes to market Tesla-powered 2014 B-Class EV in U.S.

Looks like another Tesla Motors investor will be looking to cash in on their connection. Autoweek reports Mercedes-Benz will offer their B-Class in the U.S. with Tesla propulsion.
The magazine says their source at the German automaker confirms plans for a B-Class electric-only vehicle. While Tesla already provides battery packs for the battery-powered Smart ForTwo, the B-Class EV will reportedly have Tesla batteries, motor and other components. U.S. residents should be able to procure one sometime in 2014.
The same Mercedes source says plans for a hybrid B-Class have been postponed for now. Adding a range-extending, gasoline-powered engine to an electric vehicle would put the car into a different class for which rebates and incentives aren't as favorable in the States.

2015 Mercedes-AMG C63 S First Drive [w/video]

As I mashed the throttle heading into the back straight of a nearly three-mile-long race track, I couldn't help but center my mind on two ostensibly disparate subjects: physics and pistons. If the heart of an automobile is its engine, the heart of the engine are its rotating bits – the crankshaft, pistons and the block they're nested inside. It seems fitting, then, that the internals of the twin-turbocharged 4.0-liter V8 typify the brand-new 2015 Mercedes-AMG C63 sedan I found myself piloting in Portugal. Whereas the last C-Class AMG availed itself of a brute of an engine, employing 6.2 liters of displacement to make its 451 horsepower the old fashioned way, the latest AMG's V8 engine has been downsized radically. I had the opportunity earlier in the day to actually hold the pistons of the new 4.0 Biturbo V8 in my hands, alongside those of the outgoing 6.2. The difference in size is staggering, the new lumps looking downright picayune in comparison to the latter. These eight seemingly diminutive pistons turn combustion into crankshaft-spinning power inside a block that is smaller, lighter and more compact than I'd have thought possible, considering the prodigious output the engine spits out. I had gone into this assignment expecting to pen an ode to lost love; a sonnet of sorrow bemoaning the switch from massive cylinders to wheezing power adders. But I was wrong. In fact, the report that follows may indeed read a little like a love song, except it will heap praise not on what used to be, but instead on what is now possible. The new heart of AMG more than makes up for its reduction in size by relying on turbochargers and smart engineering to turn just 4.0 liters into 469 horsepower and 479 pound-feet of torque starting at just 1,750 rpm, or as much as 503 ponies and 516 lb-ft in uprated S guise. Foot to the floor, eyes focused on the turn ahead, a hard right-hander named Primeira that requires hard braking and quick reflexes, I had a fleeting moment of clarity: These are some hard-working pistons. A few days on the street and track in and around Faro, Portugal, has convinced me that the new Mercedes-AMG C63 is a better car in any meaningful measurement than it was before. And I'll go one step further. Not only is this the best C-Class AMG ever, it's also my new favorite in the hotly contested segment that includes such knee-benders as the BMW M3 and M4.

Brabus spools up new 850 6.0 Biturbo Coupe

With a 5.5-liter twin-turbo V8 cranking out 577 horsepower and 664 pound-feet of torque, the Mercedes-Benz S63 AMG Coupe is not the first vehicle we'd figure was in need of an upgrade. But the folks over at Brabus have evidently felt otherwise, bringing the 850 6.0 Biturbo Coupe to the Geneva Motor Show this year. Now the name might be slightly misleading, but not by much: the revving heart of this beast has been bored out to 5.9 liters and its output raised to 838 horsepower (by our standards). The modified engine also includes new turbochargers, breathing apparati and a remapped ECU to produce an even more prodigious 1,069 pound-feet of torque – although to keep the whole thing from going up in flames, Brabus has limited that last figure to 848 lb-ft. The top speed has been limited to "only" 217 miles per hour to keep the tires from melting, but it'll reach 62 mph from a standstill in just 3.5 seconds. That makes this bahn-stormer blisteringly fast, though the seven-speed automatic transmission and all-wheel drive system have been left largely unchanged. Naturally that's not the end of the story, as the Brabus 850 6.0 Biturbo Coupe also features a full new carbon-fiber aero kit, wheel options ranging from 18 inches to 22, a completely refitted interior and oh, so much more. Chances are you'll never see one sitting still, so you'll want to scope it out in the slideshow of live images from the floor of the Geneva Palexpo for a closer look. Related Video:
