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.

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.

VW could look outside its own ranks for next CEO

Companies have two options when coming up with succession plans – hire within, or go outside its ranks. Either choice comes with advantages and disadvantages, to be sure. Hiring within means generally getting someone familiar with the company and its culture and traditions, while going outside is ideal if you're looking to shake things up and bring in fresh ideas. It's unclear which avenue the Volkswagen Group will go down when it comes time to replace its head man, Herr Professor Doctor Doctor Herr Martin Winterkorn, but he isn't ruling out a trip outside of Wolfsburg. Winterkorn has already given the reins of the VW brand to former BMW board member Herbert Diess, while Andreas Renschler, a former Daimler board member, is heading up VW's truck group. Now, Winterkorn has made some statements to a German weekly that indicate the most important thing about his successor isn't necessarily his (or her, though no women appear to be on the short-list) previous employer, Motoring.com.au is reporting, so much as his qualities as a leader and an engineering background. "A Volkswagen boss has to have a big affinity to our products. He needs to be close to customers and he needs to have a relationship with dealers," Winterkorn told Stern. "Like always, it depends on the personality and it also helps if the candidate is an engineer." Motoring throws out a couple of potential candidates from within, including Porsche boss Mathias Muller, Audi Chairman Rupert Stadler and engineering guru Ulrich Hackenberg, in addition to both Diess and Renschler. And while each candidate has a lot of potential, the only thing that's guaranteed right now is what Winterkorn has already said: "The decision about who will succeed me is not an easy one for the supervisory board."
