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:

Daimler exec hypothetically discusses 3-cylinder engines for small hybrids

Is three the magic number of cylinders for Mercedes-Benz parent Daimler and its efforts to build smaller powertrains for its compact hybrids? Potentially, yes, the German automaker could see the need for three-cylinder mills, Automotive News reports. The company doesn't have any plans for them as of yet, though. Daimler executive Bernhard Heil talked with Automotive News about the challenges of using four-cylinder engines in a front-wheel-drive setup and said that three-cylinder engines could work in transverse-mounted powertrains for hybrid cars. For now, though, the company doesn't actually have any plans to go in that direction, Mercedes-Benz spokesman Christoph Horn said in an e-mail to AutoblogGreen. Horn wrote that Heil "actually said that if ever MB would use a three-cylinder engine than [it would be] in a configuration where space is restricted, such as when using a hybrid power train in a compact car." Of course, the only compact "hybrid" that Mercedes-Benz has is the 2015 C-Class, but that refers to the "hybrid" body is made of 48-percent aluminum, up from the current nine percent, as well as steel. It has nothing to do with the powertrain. Beyond that, there's always the Mercedes-Benz S500 Plug-in Hybrid that the company unveiled at the Frankfurt Motor Show last fall, but that model, which will debut in Europe later this year and arrive stateside next year, has a 3.0-liter turbocharged V6 and an 80-kilowatt electric motor that propels the plug-in from 0 to 62 miles per hour in 5.5 seconds. Not exactly three-cylinder territory, that.

Chris Harris falls in love with Mercedes-AMG GT at Laguna Seca

It's not every day that an automaker goes down a market segment and still comes off as even more ambitious, but that's exactly what Mercedes has done with the new AMG GT. While the SLS was bigger and more expensive, with the new GT, Mercedes has set its sights on one of the most iconic sports cars of all time. That, of course, would be the Porsche 911, and the big question is whether Benz has achieved its target. For the answer, we turn to none other than the Monkey himself – the inimitable Chris Harris, who recently went solo with his own YouTube channel. And for his latest segment, he took the latest German sports car around no less suitable a track than Mazda Raceway Laguna Seca.
