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 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.

Frankfurt Motor Show Notes: Why Jaguar decided to build an SUV

It was inevitable. Jaguar had to make an SUV, and that notion became reality this week with the debut of the F-Pace, an all-wheel-drive five-seater that will launch in the United States next spring. Some purists may cringe. But in an era when Porsche, Bentley, Lamborghini, Rolls-Royce, Aston Martin, and other traditional luxury brands are all building or (planning to build) SUVs, Jaguar had to evolve. While it seems like a leap for Jaguar to make an SUV, longtime design director Ian Callum said it's been in the works for years. "The first time I was asked the question was when I arrived 16 years ago," he said. So in 1999 (and probably well before that), Jaguar was already thinking SUV. What took so long? "It wasn't a priority," Callum said. Jaguar was concentrating on fixing its existing lineup, which was pockmarked with holes and poorly selling products, like the X-Type. Along the way, Jaguar and sister brand Land Rover were sold by Ford to Indian conglomerate Tata Motors. Flash forward several years, and Jaguar and Land Rover are both experiencing a resurgence in the United States and around the world. Jaguar's lineup is flush with the E-Type's modern successor, the F-Type, plus a new version of the XF. The XJ received a 2016 freshening, and the smaller XE sedan is on the way. Jaguar put its house in order as other factors conspired to make a crossover timely. Fuel prices stayed relatively low, and consumers in the US and China remained steadfast in their love for utility vehicles of all stripes. Making a Jaguar SUV became a priority. "The world was telling us in no uncertain terms this is what they wanted," Callum said. "Not to be in the sector would be a little naive for the sake of purity." Jaguar proved its intent two years ago when it revealed the C-X17 crossover concept at Frankfurt, and the final production model is close to the prototype's striking looks. "I thought we managed to maintain that spirit," Callum said. It's a true Jaguar, with cues from the F-Type, 1968 XJ, and other famous models. Who would have thought Jaguar would make an SUV? "I certainly didn't," Callum admitted. But the F-Pace is here. If Callum is okay with it, purists can be, too. Quick Hits Opel retrenches for 2016 and beyond Opel used the Frankfurt show to display its new generation of the Astra, a critical vehicle line for the German division of General Motors.
