Watch Schumacher's hot lap of N"urburgring in Mercedes F1 car

In advance of the Nürburgring 24-hour race last weekend, Mercedes-Benz put on a demonstration that had Michael Schumacher playing catch-up in a Formula One car against four examples of AMG metal. There were four cars sent off in staggered starts before Schumacher: an A45 AMG, E63 AMG 4Matic, SLS AMG Black Series, and an SLS AMG GT3 car. "Mr. Formula One," as the German television commentators call him, left three minutes after the SLS AMG GT3.
There are two videos of Schumacher's lap, the first is on-board footage - and even though there were several GoPros on the car the POV never cuts away from the front wing. You can hear the throttle and tell he's not pushing it, you can also tell how bumpy the track is. The second video is footage from the German Sport1 channel - with commentary in German - that shows all the cars taking off and takes the aerial view of proceedings. He looks to be going a lot faster in that one. You can compare and contrast yourself with the videos below.
Oh, and it's worth noting that, even with the likely restricted car, and the made-for-TV environment, Schumi turned in a quick lap. The nose camera shows the F1 car start to slow down on the back straight, near the start/finish line, right around the modern-length track record time of six minutes and eleven seconds.

Mercedes-Benz engines with 48-volt systems coming in 2017

As part of a big green push announced yesterday, Mercedes-Benz is jumping into the world of 48-volt power. The company will launch a new family of efficient gasoline engines next year and will begin rolling out 48-volt systems with it, likely in its more expensive cars first. Mercedes will use the 48-volt systems to power mild-hybrid functions like energy recuperation (commonly called brake regeneration), engine stop-start, electric boost, and even moving a car from a stop on electric power alone. These features will be enabled through either an integrated starter-generator (Mercedes abbreviates it ISG) or a belt-driven generator (RSG). (RSG is from the German word for belt-driven generator, Riemenstartergeneratoren. That's your language lesson for the day.) Mercedes didn't offer many other details on the new family of engines. There are 48-volt systems already in production; Audi's three-compressor SQ7 engine uses an electric supercharger run by a 48-volt system, and there's a new SQ5 diesel on the horizon that will use a similar setup with the medium-voltage system. Electric superchargers require a lot of juice, which can be fed by either a supercapacitor or batteries in a 48-volt system. Why 48-volt Matters: Current hybrid and battery-electric vehicles make use of very high voltages in their batteries, motors, and the wiring that connects them, usually around 200 to 600 volts. The high voltage gives them enough power to move a big vehicle, but it also creates safety issues. The way to mitigate those safety issues is with added equipment, and that increases both cost and weight. You can see where this is going. By switching to a 48-volt system, the high-voltage issues go away and the electrical architecture benefits from four times the voltage of a normal vehicle system and uses the same current, providing four times the power. The electrical architecture will cost more than a 12-volt system but less than the complex and more dangerous systems in current electrified vehicles. The added cost makes sense now because automakers are running out of ways to wisely spend money for efficiency gains. Cars can retain a cheaper 12-volt battery for lower-power accessories and run the high-draw systems on the 48-volt circuit. The industry is moving toward 48-volt power, with the SAE working on a standard for the systems and Delphi claiming a 10-percent increase in fuel economy for cars that make the switch.

Carlsson turns Mercedes-Benz SLK into 610-HP hill-climb clawer

Carlsson's race-tuned versions of the Mercedes-Benz SLK have been taking checkered flags for years, and we won't be surprised if its SLK 340 hill climber fares any different. Developed by multiple German and Swiss hill climb champion Reto Meisel, the carbon-bodied SLK 340 with lightweight brakes and a closed underbody weighs 1,716 pounds. Propelling that tiny bit of weight is a 3.4-liter V8 from Judd with 610 horsepower, and it rolls on 18-inch wheels shod in Avon tires.
It will debut at the Geneva Motor Show before beginning its racing campaigns in the summer. This one won't just tear up roads in Europe, though - Meisel says he plans on bringing it to the Pikes Peak International Hill Climb. The press release below has more details.
