Mercedes unveils GLC350e 4Matic PHEV

Mercedes-Benz intends to introduce at least 10 plug-in hybrid models to the market by 2017, and the the Mercedes GLC350e 4Matic is the latest one to show its electrified face. It's also the second crossover from the company to offer a PHEV version following the GLE550e 4Matic. Mercedes isn't releasing all of the details about the plug-in GLC yet, but it combines an internal combustion engine making 208 horsepower and a 114 hp electric motor with a seven-speed gearbox. Total torque is 413 pound-feet. The combo is enough to get the all-wheel drive crossover to 62 miles per hour in a purported 5.9 seconds and a claimed top speed of 146 mph. Fuel economy in the European cycle is estimated at the equivalent of about 90 miles per gallon, and there's a 21-mile pure electric range for zero-emissions cruising. Based around the newly introduced GLC-Class, buyers can still order a plethora of luxurious amenities, but the plug-in powertrain also comes with a few tweaks to help drivers maximize fuel economy. There's a haptic accelerator with a resistance point to indicate the switch between electric and combustion power. In addition, the hybrid system can anticipate the road ahead through radar and GPS to manage things as efficiently as possible. One of the GLC hybrid's biggest advantages when it arrives is the small field of competitors. Neither BMW nor Audi currently have a compact luxury crossover of this size with a hybrid option in the US. That really only leaves the Mercedes to take on the Lexus NX300h with total system output of 194 hp, and that's not even a plug-in. The GLC350e 4Matic isn't part of the new model's initial launch lineup in the US. It should be coming along later, though. Key topic: Energy efficiency - Economy on four wheels A revised all-wheel-drive powertrain, the outstanding aerodynamics and the intelligent lightweight design are the primary reasons for the high energy efficiency of all the new GLC models. The conventional diesel and petrol models boast significant reductions of up to 19 percent in both fuel consumption and CO2 emissions in comparison to the previous generation, while at the same time improving performance.

Ferrari hails Vettel as the 'moral winner' after 'stolen' F1 race

MONTREAL — Ferrari hailed Sebastian Vettel as the moral winner of the Canadian Grand Prix on Sunday while the German raged at being robbed of victory by race stewards. "They are stealing the race from us," the angry German exclaimed over the team radio as he was told he was under investigation after running off the track and into the path of Mercedes rival Lewis Hamilton. Vettel was given a five-second penalty, finishing first but having to hand victory to Hamilton. "No, no, no. Not like that. You have to be an absolute blind man, you go on the grass how are you supposed to control your car? This is the wrong world," the Ferrari driver yelled after being notified of the penalty. "It's not making our sport popular, is it? I mean, with these kind of decisions," he told Sky Sports television after the podium ceremony. He had earlier parked up in the wrong place and stormed straight to the Ferrari hospitality area before returning to the pitlane. There he rearranged the numbers in front of the cars, switching the 'one' board from Hamilton's car to the space where his Ferrari should have been. "If it had happened to me I would have kicked the damn board and thrown it against the car," said Mercedes F1 boss Toto Wolff, whose team has now won the first seven races of the season. "I am of course biased for Mercedes, and I say there is a rule that says you need to leave a car's width when you go off the track and I think his instinctive reaction was 'I need to protect that position' and maybe that was a tiny bit too far." Wolff said he was surprised by the stewards' decision but also defended them. The officials included experienced Italian racer Emanuele Pirro, a former F1 driver and five times winner of the Le Mans 24 Hours sportscar race. "I think the stewards up there need to be people that need to be supported," said Wolff. "There is Emanuele up there, it doesn't go any more professional and experienced than Emanuele. Said Vettel, "People want to see us race and that was, I think, racing. I hope the people come back, that's the main thing obviously... it's just a shame when we have all these little funny decisions." Ferrari team boss Mattia Binotto indicated there could be no appeal by the Italian team but said there was no doubt about the real winner. "It's not down to us to decide, and that's the sport. But certainly if you look at the crowd, everybody I think today believes that there was nothing Sebastian could have done," he said.

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.
