2015 Mercedes-AMG G65 Review

A German friend who lives in Munich told me she might have to retrieve her car from Innsbruck, Austria while I was in Germany to visit her. I said I'd be happy to chauffeur her to the Tyrol in a Mercedes-AMG G65. She responded to the offer with this question: "You mean – in the G65 Rap Train?" I had no idea what it meant, but the name stuck. Her reasoning was that I would be taken for an American rapper, because what other black American would be cruising south, East, and west Germany for ten days in a 272,000-euro, 5,676-pound chunk of... well, let's just say it: bling. Mercedes created the G65 by installing its 604 horsepower, 6.0-liter, twin-turbo V12 in the G-Class engine bay, and laying oodles of quilted leather inside the cabin. Introduced to markets outside the US in 2012, it sat above the twin-turbo, V8-powered G63 that remained the top-of-the-line here. After years of denial, US buyers will finally get their chance to buy the G65 in November for $217,900. It's a 272,000-euro, 5,676-pound chunk of... well, let's just say it: bling. A grandiose, body-on-frame SUV with a price as momentous as its horsepower might appear silly, but Mercedes can point to plenty of good reasons to bring it here now. In the abstract there's customer demand, AMG boss Tobias Moers having said, "There are AMG fans for whom our V12 biturbo engine is the measure of all things." Concrete justification is in the sales numbers: in May 2010 the G-Class sold 99 units in the US on its way to 919 units for the year. In May 2015 US buyers took home 302 G-Classes, and only five months into this year the brand has sold 1,448 of its ultimate off-roader. The G63 outsold the less expensive G550 in the US in both 2013 and 2014. In 2013 the G63 was the best-selling AMG product in the US, and the G lineup posted its best-ever sales year globally during what was its 35th year on the market. Competitive reasons are likewise substantial. The Bentley Bentayga, Range Rover Sport SVR, Lamborghini Urus, and a Rolls-Royce "that can cross any terrain" will soon join the retail celebration of six-figure SUVs. By getting the G65 here first, Mercedes gets the head start. The burble dripping from the quad pipes is quieter on G65 than the G63. In spite of its price, the Rap Train isn't ostentatious – the sample I was given to drive wearing a beautiful coat of muted satin gray. Because Mercedes is going for a more elegant look for the top of the line G-Wagen, the US-market G65 comes without bull bars.

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.

Mercedes celebrates with World Championship edition SL63

Mercedes has plenty to be celebrating at the moment, having just won the Formula One World Championship in spectacular style – taking the constructors' title by a huge margin and the top two slots in the drivers' standings as well. It almost goes without saying that the German outfit would celebrate with a special edition, and that's just what we're looking at here. Presented at a special celebratory Stars & Cars event in Stuttgart in front of 50,000 jubilant fans, the Mercedes-Benz SL63 AMG World Championship 2014 Collector's Edition is based on Benz's twin-turbo V8-powered roadster but with some choice upgrades. Two versions will be offered: one in black with gold accents (displayed with the Silverstone circuit layout), the other in white with silver accents (and the Hockenheim map). One was designed by Lewis Hamilton, the other by Nico Rosberg. We'll let you sort out which one was done by which, but either way there'll only be 19 examples, each dedicated to a different grand prix circuit in the championship which Mercedes positively dominated – winning all but three, scoring eleven one-two finishes and landing on the podium at each and every one.
