Mercedes-Benz C-Class scores well in TUV lifecycle analysis

Mercedes-Benz drivers and treehuggers don't always go hand in hand, but, like a lot of other companies, the German automaker is looking to boost its green cred. This time, it's all about the car's lifecycle carbon footprint. The Daimler AG unit is using its new C-Class sedan as an example of how it's making progress in that department. Mercedes-Benz, citing the inspection authority TUV Sud, says the 2015 C-Class has a 10-percent lower lifecycle carbon footprint than its 2014 predecessor, based on driving about 125,000 miles over the life of the car. About 95 percent of the car (by weight) is recyclable, slightly higher than the average for most vehicles, and the model has upped its amount of recyclable materials up by 23 percent and increased its use of "natural materials" by 55 percent. Better aerodynamics also helps things out on the fuel-economy front, Benz says. Taking a longer view, the 2015 C-Class's carbon footprint is 28 percent better than the 2007 version that launched the vehicle line. The 2015 C-Class hasn't received a fuel-economy rating from the US Environmental Protection Agency, which tagged the 2014 C350 with a combined fuel-efficiency rating of 24 miles per gallon from its 3.5-liter 6-cylinder engine.

TUV Environmental Certificate: The new C-Class makes its mark with an exemplary life cycle assessment Stuttgart, Mar 28, 2014 The C-Class sets efficiency benchmarks for its class, helped by an intelligent lightweight concept, excellent aerodynamics and new, frugal engines. The neutral inspectors from the TUV Sud technical inspection authority have confirmed the high level of environmental compatibility of the new Mercedes-Benz C-Class. Besides a sensuous, clean-cut design, a top-class interior and a host of technical innovations, the premium saloon also boasts an exemplary life cycle assessment, which is why it has been awarded the Environmental Certificate in accordance with the ISO 14062 standard. Professor Dr. Herbert Kohler, Chief Environmental Officer at Daimler AG: "Our engineers have pulled out all the stops in an effort to lower fuel consumption while at the same time further accentuating the car's sporty character. By employing an intelligent lightweight design with a high proportion of aluminium, for example, it has been possible to make the new C-Class up to 100 kilograms lighter than its predecessor.

Race recap: 2015 Abu Dhabi Grand Prix is Germany rising as sun sets

Mercedes-AMG Petronas driver Nico Rosberg Rosberg doesn't attribute anything mystical to the form that got him ahead of teammate Lewis Hamilton. He said simply, "Before it was close in the other direction, now it's close in this direction." Mercedes non-executive chairman Niki Lauda went further, saying Rosberg's "brain has switched." Under the desert spotlights it switched so far ahead that Lewis Hamilton qualified nearly four tenths behind the German. Kimi Raikkonen flew the scarlet for Ferrari in third position. Being three spots ahead of Valtteri Bottas gave Raikkonen a huge advantage in locking up fourth position in the driver's championship. Even if he doesn't care about it, as he's publicly stated, Ferrari probably does. Teammate Sebastian Vettel was classified 16th after the German slowed down after making a mistake on his final hot lap, and neither he nor his engineer realized how quickly times were falling on a cooling track. He'd be promoted to 15th when Lotus driver Romain Grosjean was penalized for a gearbox change. Sergio Perez knocked it out of the park for Sahara Force India, claiming fourth ahead of Daniel Ricciardo in fifth for Infiniti Red Bull Racing. Williams driver Bottas was in sixth, in front of the second Force India of Nico Hulkenberg and the second Williams of Felipe Massa in eighth. Daniil Kvyat ensured both Red Bulls were in the top 10 with his ninth position, and Carlos Sainz got the upper hand in qualifying over his Toro Rosso teammate Max Verstappen for the final time this year, rounding out the top 10. Beyond Nico Rosberg's mind, one of his weaknesses was his slow starts. Those are stronger, too, the German tearing off away from the field when the lights went out. Hamilton bogged enough to have to defend from Perez behind, the Mexican trying to slide between Hamilton and Raikkonen on the run to the first corner. Rosberg held the lead into Turn 1 and likewise held it through Turn 21 on the last lap of the race, only ceding it during pit stops. Rosberg's 14th victory gets him level with Graham Hill on the wins list – on the anniversary of Hill's death in a plane crash – and marks the first time in his 10-year F1 career that he's won three races in a row. More proof of his strength: the last few races we haven't heard Rosberg ask for regular updates about what Hamilton's doing, he just drives. Hamilton gave it his best but that wasn't enough.

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.
