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.

Gordon Murray, F1-driven production and .. the Pontiac Fiero

Gordon Murray's design and engineering chops are unquestionable. But does his carmaking approach owe something to the short-lived Pontiac Fiero, a scrappy little car program that emerged from GM against serious resistance? Murray had a Formula One career that ran from 1969 to 1991, with stints at Brabham ('69 to '86) and McLaren ('87-'91), that resulted in several shelves' worth of trophies for the cars he was instrumental in designing. He moved on to McLaren Cars, the consumer side of things, where, during his tenure from 1991 to 2004, he helped design the McLaren F1 and the Mercedes-Benz SLR McLaren, two cars that took learnings from his two decades in Formula One. What do all of these cars have in common? Three things: They are light. They were built in limited numbers. And they were (and are) exceedingly expensive—when the McLaren F1 debuted in 1994, it stickered at $815,000. Murray went on to establish Gordon Murray Design in 2007. GMD has created some interesting concept vehicles, such as the diminutive T.25 city car (94.5 inches long, 51.1 inches wide and 55.1 inches high), and the OX, a lightweight truck for the developing world that packs like an IKEA shelf and is working toward realization through a worthy crowdfunding campaign established by the Global Vehicle Trust. Now he has created a vehicle manufacturing company, Gordon Murray Automotive, that will use manufacturing methods that he developed under the moniker "iStream." Unlike a unibody, there are the "iFrame," a cage-like construction made with metallic components, and the "iPanels," which are composite. The panels aren't simply a decorative skin; they actually provide structure to the vehicle. Presumably this has something of the F1 monocoque about it. Going back to the three elements, (1) this arrangement results in a vehicle that can be comparatively light; (2) Murray has indicated that his manufacturing company will be doing limited-run production; and (3) to launch Gordon Murray Automotive they are going to be building a flagship model, about which Murray said, "With our first new car, we will demonstrate a return to the design and engineering principles that have made the McLaren F1 such an icon." Which seems to imply that it will be on the pricey side. According to the company's verbiage, "iStream forges an entirely new production method that defies conventionality with its Formula One-derived construction and materials technologies." It also sounds a whole lot like ...

Weekly Recap: Toyota propels hydrogen fuel cells

Toyota is serious about hydrogen fuel cells, and it wants the auto industry to follow suit. The Japanese automaker said this week it's releasing 5,680 fuel cell patents from around the world, including technologies used on its upcoming sedan, the 2016 Mirai. The move is unusual, but not unprecedented, as Tesla similarly released its electric vehicle patents last year. The idea for Tesla, and now for Toyota, is to spur development of alternative propulsion. "By eliminating traditional corporate boundaries, we can speed the development of new technologies and move into the future of mobility more quickly, effectively and economically," said Bob Carter, Toyota Motor Sales senior vice president of automotive operations, in a statement. Toyota's fuel cell patents will be free to use through 2020, though patents related to producing and selling hydrogen will remain open forever. Toyota said it would like companies that use its patents to share their own hydrogen patents, but won't require it. "What Toyota's doing is really a logical move, and really a good move for the industry," Devin Lindsay, principal powertrain analyst with IHS Automotive, told Autoblog. The announcement was made at the Consumer Electronics Show in Las Vegas. It comes as Toyota prepares to launch the hydrogen-powered Mirai in a limited number late this year in California. The launch will be extended to the Northeastern United States next year. Toyota also has announced plans to support networks of fueling stations in each region to try to smooth consumer adoption. The Mirai has a 300-mile range on a tank of hydrogen, and it takes about five minutes to refill. Fuel cells have been receiving increased attention recently, and Audi and Volkswagen debuted hydrogen-powered cars at the 2014 Los Angeles Auto Show. Honda, another proponent of the technology, also showed its updated FCV concept in November in Japan. The company, however, has delayed its fuel cell sedan a year until 2016. Like Toyota, Honda says its hydrogen-powered car will have a range of 300 miles or more. Meanwhile, Hyundai currently offers leases for fuel-cell powered Tucsons, which have a 265-mile range, in Southern California. Despite the optimism some automakers have for fuel cells, the technology still faces barriers. A lack of filling stations has long held it back, and many consumers are not familiar with the potential benefits.
