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.

Race recap: 2016 Australian F1 Grand Prix a rowdy start to season

The three brief Formula 1 tests ahead of the current season belied how much had gone on since the last race in November: Infiniti subbed out for Tag Heuer, Renault is back, the all new Haas F1 team, a revamped Manor, three brand new drivers and two returning drivers, a raft of regulation changes among the newly tilled soil. The four engine manufacturers spent a combined 67 tokens among the 138 in the kitty, Renault using just seven of their 32. The only conclusive proof to come from the annual intermission was the otherworldly capability of Mercedes-AMG Petronas. The Silver Arrows didn't even try the super- and ultra-soft tires, focusing on reliability instead of speed. The result? They ran more than 19 race distances, obliterating the lap totals of every other team. There are certainly a few people who enjoyed the complicated new rolling-elimination qualifying format fast-tracked to approval just a few weeks ago. They were wildly outnumbered by those who thought it was awful, including the same team heads who voted for it. We'd probably have to go back to the debacle at the 2005 Indianapolis Grand Prix for an equivalent fiasco when Michelin pulled its teams over safety fears, leaving six cars out of 20 to qualify. In Australia, within 24 hours of the conclusion of qualifying, the new format had itself been eliminated. Nevertheless, qualifying also taught us what didn't happen over the winter: any other team progressing enough to outduel Mercedes. After admitting that he dropped off after winning the championship last year, then getting questioned in the press for some dubious off-season activities, Lewis Hamilton proved he can still turn it on when he wants to. The Brit smoked the Albert Park track in 1:23.837, more than three-tenths of a second ahead of teammate Nico Rosberg in second place. Ferrari did make strides during the off-season, but only enough to keep the same gap it had to Mercedes last year: Sebastian Vettel lined up third, a half-second behind Rosberg, teammate Kimi Raikkonen another four-tenths back in fourth place. Max Verstappen said Toro Rosso is the best of the rest, the Dutchman taking fifth place in front of Felipe Massa for Williams in sixth and Toro Rosso teammate Carlos Sainz in sixth. Daniel Ricciardo – who wasn't smiling after qualifying – kept Red Bull and its new "Tag Heuer" engines in the conversation with eighth on the grid.

Daimler boss says fuel cell vehicles will be disappointing for at least 10 years

Daimler AG CEO Dieter Zetsche is pretty confident about the imminence of self-driving cars. Hydrogen fuel-cell vehicles? Not so much. He didn't even get into the possibility of self-driving fuel-cell vehicles, but we're okay taking future technologies one at a time. Zetsche, in an interview from the Detroit Auto Show last week, said the automotive industry is about a decade away from avoiding disappointing experiences with production fuel-cell vehicles, In Auto News says. Zetsche was quick to note that the Mercedes-Benz parent entered into a fuel-cell partnership with Ford and Nissan early last year in an effort to split costs and speed things along, with the expectation that the group would develop something together by 2017, but even that won't be able to smooth things out fully. Toyota and Hyundai have said they'd have their own production vehicles on the road sooner than that. Multi-corporation-partnerships notwithstanding, Zetsche bemoaned the high costs, lack of vehicle volume and minimal refueling infrastructure as the proverbial roadblocks to more rapid development and adoption of fuel-cell vehicles. As it is, the US has just 10 publicly accessible hydrogen refueling stations, eight of which are in Southern California, according to the US Department of Energy. As for autonomous automobiles, Zetsche was more upbeat. Daimler already has what it calls the "Distronic" cruise control system that includes an automatic braking feature and has successfully driven a car 60 miles with "with relatively modest adjustments to the existing onboard technology."
