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 has X6 in its crosshairs with the GLE Coupe

In the last month, Mercedes-Benz has taken the sheet off two versions of its GLE Coupe: the 450 AMG and Mercedes-AMG GLE63 S. The models represent the German brand's shot across the bow at the BMW X6 in the luxury-crossover-four-door-coupe segment, including the high-performance M version of the bodystyle. Not much separates the styling between the two versions. Both feature sweeping arches over the hood and roofline to create their coupe-like appearance. Up front there are huge air intakes with a wide grille on top that's bisected by the brand's traditional star. The AMG version tweaks that look with the division's A-wing grille. At the rear, there are wraparound taillights and a chrome strip. The higher performance version also sports a modified diffuser and air outlets. No matter which one buyers choose, they get a healthy amount of power nestled under the hood. The 450 AMG packs a 3.0-liter, twin-turbo V6 with 362 horsepower and 384 pound-feet of torque with a nine-speed automatic. Opting for the GLE63 means a massive boost with 577 hp and 561 pound-feet from a 5.5-liter twin-turbo V8 routing through a seven-speed auto gearbox. Either way, customers get Merc's 4Matic all-wheel drive system. The luxury crossover coupe segment is often maligned for looking awkward, but Mercedes clearly sees room to grow there. Check them both out live from the 2015 Detroit Auto Show floor in the galleries above.

Mercedes GLE Coupe to feature in Jurassic World

It was back in 1997 that Mercedes first got into the crossover game with the launch of the M-Class, and most of us got our first look at the luxury high-rider when it debuted on the big screen in the Jurassic Park sequel The Lost World. It's been 18 years since that event, but now its successor is set to appear in the revival of the once-popular movie franchise. Come June 12, moviegoers will be able to catch the new Jurassic World film at their local theaters, but the dinosaurs will have to share the spotlight with the new GLE Coupe. The slant-roofed crossover that'll share its underpinnings with the M-Class' successor and challenge the BMW X6, will appear in the film in GLE 450 AMG Sport guise, and Universal Studios apparently did a good enough job keeping the Mercedes under wraps during filming until its release just a month ago. Mercedes Continues Its Decades Long Relationship with Universal: Mercedes-Benz GLE Coupe launches in Universal Pictures' Jurassic World Stuttgart, Jan 08, 2015 Stuttgart. On-screen, multiple Mercedes-Benz vehicles are once again in on the Jurassic action. Twenty-two years since the events of the original film, Steven Spielberg returns to executive produce the long-awaited next installment of his groundbreaking Jurassic Park series, Jurassic World. During their adventures in the jungles of Jurassic World, the characters played by Chris Pratt and Bryce Dallas Howard put their trust in the off-road capabilities of various Mercedes-Benz vehicles – especially in the all-new GLE Coupe, which appears in its series-look for the first time. Colin Trevorrow directs the epic action-adventure from a screenplay he wrote with Derek Connolly. Frank Marshall and Patrick Crowley join the team as producers. Jurassic World will be released in 3D by Universal Pictures on June 12, 2015. The partnership continues the relationship between Universal and Mercedes-Benz, first forged in 1997's The Lost World: Jurassic Park, when Mercedes introduced the M-Class vehicle. "We are delighted to have been able to support this epic action-adventure with our vehicles," said Dr. Jens Thiemer, Head of Marketing Communications for Mercedes-Benz Cars. "Our wide range of SUVs in particular fit perfectly with Jurassic World's various requirements, with the focus on our new trendsetter, the GLE Coupe." Above all, it is the new GLE Coupe that shows off its best side.
