Mercedes forced to lower MPG ratings on two C300 models *UPDATE

*UPDATE: Donna Boland, manager of corporate communications at Mercedes Benz USA, told AutoblogGreen that the sticker change only applied to around 500 C-Class vehicles on dealer lots, since a new C-Class came out in late August. "About 500 are left in the United States, and we've relabeled them," she said. First Hyundai, then Ford and now Mercedes-Benz. The list of companies that have had to change their vehicles' official EPA fuel economy ratings has just grown by one with the announcement that the 2013 and 2014 C300 4-Matic FFV and PZEV versions need to have their EPA labels adjusted. The changes aren't massive, at most one mile per gallon. The changes aren't massive, at most one mile per gallon, but they are lower than before. The FFV version goes from 20 to 19 mpg in the city while the PZEV drops one mpg across the board from 23/20/29 combined/city/highway) to 22/19/28. The FFV's combined (22) and highway (27) ratings stay the same. Other Mercedes vehicles that were spot checked turned out to have accurate labels. The problem, which is reminiscent of the issues that Ford had with the Total Road Load Horsepower, was that "Mercedes underestimated the impact of aerodynamic drag and tire rolling resistance known as 'road-load,'" the EPA said in a statement you can read below. We have asked Mercedes for more information on the issue but have not yet heard back. We're not sure how many vehicles the EPA is retesting (or asking to be retested), but the agency says that the C300 models were evaluated again by Mercedes "with EPA oversight" and the EPA did its own tests at the National Vehicle and Fuel Emissions Laboratory in Ann Arbor, MI. Christopher Grundler, the director of EPA's Office of Transportation and Air Quality, said that the EPA knows that the changes are minimal, but that, "it is important that our oversight system is producing the correct results because even one MPG matters to consumers." In case you need a primer in the recent history of companies adjusting their EPA numbers, check out this and this. Based on today's news, we won't be surprised to hear more changes are coming. EPA Requires Mercedes-Benz to Correct Fuel Economy Labels for Two C300 4-Matic Vehicles WASHINGTON - The U.S. Environmental Protection Agency (EPA) is revising estimates for two 2013/2014 Mercedes C300 4-matic vehicles, the FFV and PZEV, to ensure consumers are given accurate fuel economy values.

Daimler, Geely mull China as production hub for hybrid powertrains

FRANKFURT — Daimler and Geely on Friday said China could emerge as a manufacturing and export hub for hybrid powertrains jointly developed for Volvo and Mercedes-Benz cars. Earlier this week, Daimler said it would cooperate with China's Geely to build next-generation combustion engines for use in hybrid vehicles. The engines will be produced in China as well as in Europe, and Geely and Daimler will cooperate in engineering, sourcing and production, the companies said in a joint press release. "The export of the engine from China is considered to be an option," the release further said. Mercedes-Benz aims for more than half of its passenger car sales to be comprised of plug-in hybrids or purely electric vehicles by 2030. Geely is ChinaÂ’s most internationally known automaker. It owns Volvo Cars and Lotus, almost half of Proton and 9.7% of Daimler. Through wholly owned company Polestar, it builds low-volume Polestar 1 hybrid performance cars in the western city of Chengdu and Polestar 2 volume sedans in Taizhou in the east. "The companies plan to develop a highly efficient modular engine," a spokesman for Daimler said, adding that it would be used in hybrid drivetrains and manufactured in Europe and China. The modular engine will be used in cars under different marques at Geely and Daimler, a person familiar with the matter said on condition of anonymity as the companies are still in the early stages of developing the engine. An Conghui, President of Geely Holding Group, President and CEO of Geely Auto Group said: “This project reflects the need for economies of scale and targeted research and development investment in clean and highly efficient powertrains and hybrid drive systems and their applications." Geely also plans to build a plant with annual manufacturing capacity of 30,000 premium EVs in the western city of Chongqing, run by a wholly owned, newly registered company, according to documents on its website. Geely and Polestar declined to comment. The plan comes as foreign automakers including BMW AG and Tesla expand EV production in the worldÂ’s biggest market, sourcing major EV components such as batteries locally and often even exporting a portion of the vehicles it builds.   Auto News Earnings/Financials Green Plants/Manufacturing Mercedes-Benz Volvo Green Automakers Future Vehicles Hybrid

Watch Schumacher's hot lap of N"urburgring in Mercedes F1 car

In advance of the Nürburgring 24-hour race last weekend, Mercedes-Benz put on a demonstration that had Michael Schumacher playing catch-up in a Formula One car against four examples of AMG metal. There were four cars sent off in staggered starts before Schumacher: an A45 AMG, E63 AMG 4Matic, SLS AMG Black Series, and an SLS AMG GT3 car. "Mr. Formula One," as the German television commentators call him, left three minutes after the SLS AMG GT3.
There are two videos of Schumacher's lap, the first is on-board footage - and even though there were several GoPros on the car the POV never cuts away from the front wing. You can hear the throttle and tell he's not pushing it, you can also tell how bumpy the track is. The second video is footage from the German Sport1 channel - with commentary in German - that shows all the cars taking off and takes the aerial view of proceedings. He looks to be going a lot faster in that one. You can compare and contrast yourself with the videos below.
Oh, and it's worth noting that, even with the likely restricted car, and the made-for-TV environment, Schumi turned in a quick lap. The nose camera shows the F1 car start to slow down on the back straight, near the start/finish line, right around the modern-length track record time of six minutes and eleven seconds.
