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.

McLaren, Red Bull and Ferrari call for unfreezing F1 engines

Formula One is a hugely expensive sport. Not only do you have enormous salaries and logistical expenses, as you would in any other sport, but each team also spends huge sums developing their own chassis from the ground up – and so too do the participating automakers in developing the engines. One of the ways the series organizers mitigate those costs is by freezing development. So once the new crop of V6 turbo hybrid powertrains were developed, that was it. But now three of the of the sport's leading teams are calling on the FIA to unfreeze engine development. Their reason? Unfair advantage. There's little question that Mercedes did the best job of developing its "power unit" to meet the new regulations that took effect at the beginning of this past season. That's how the Mercedes team won all but three of the grands prix this season and finished with at least one car on the podium at every single race. It's also a big part of how the teams that bought their engines from Mercedes this season managed to consistently outperform the other non-works-supported teams. That clear advantage is why Red Bull, Ferrari and now McLaren are calling for engine development to be unfrozen. Their argument is that, under the current locked-down status quo, their engine suppliers (Renault, Ferrari and Honda, respectively) cannot possibly catch up. So unless the FIA and Formula One Management want the next few seasons to be the kind of absolute blow-outs that this past season was, these leading teams argue, the powers that be are going to have to make some changes. For its part, Mercedes naturally counters that unfreezing engine development would send costs spiraling out of control. But then of course it stands to lose the most by re-opening engine development. If those three teams, however, closely intertwined as they are with the three other engine suppliers participating in next year's championship, manage to solicit enough support from the other customer teams and bring the matter to a vote, Mercedes may very well find itself out-numbered.

Mercedes GLE-Class shows a new face for the luxury crossover in NYC

Segments don't get much hotter than luxury crossovers at the moment, and that makes for some perfect timing for Mercedes-Benz to unveil the GLE-Class at the 2015 New York Auto Show. As a replacement for the M-Class, the new model offers a more traditional looking alternative to the styling of its swoopy sibling, the GLE-Class Coupe. Mercedes' designers crafted a nose for the GLE that gives it a strong family resemblance to the Coupe, but the rest of the shape bears a chunky, more utilitarian appearance. Elsewhere, the new model sticks with the thick C-pillar and wraparound rear glass of the outgoing M-Class but with sharper edges for a slightly more muscular look. Stepping inside, occupants find all of the German luxury brand's latest styling cues. Mercedes is making a major commitment to adding more plug-in hybrids to its vehicles in the coming years, and the GLE is one step in that process. The lineup includes the GLE550e 4Matic that pairs a 3.0-liter, twin-turbo V6 with electric assistance to produce a total of 436 horsepower and 479 pound-feet of torque. The German brand isn't going entirely green, though, and the range also includes the Mercedes-AMG GLE63 and GLE63 S, powered by a twin-turbo 5.5-liter V8 that produces 550 hp or 577 hp, respectively. Check out the photos above from the show floor to get a full look at this upscale crossover before it arrives at dealers later this year.
