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.

Recharge Wrap-up: KillaJoule hits 270 mph; Mercedes B-Class ED gets PlugShare

The Mercedes-Benz B-Class Electric Drive will get its own version of the PlugShare charging-station locator app. Developed by Recargo with the help of Daimler, the vehicle-specific app will be integrated into the car's navigation system. The system maps the location of nearby charging stations from various networks. So far, Mercedes-Benz doesn't offer a universal pay service for the various charging networks, like those offered by BMW and Nissan. Read more at Green Car Reports. HyperSolar uses solar energy to make hydrogen from water. Without using electrolyzers, HyperSolar uses a photochemical process to separate and capture the hydrogen in the water, which can then be used for clean energy, such as automotive fuel cells. The solar devices are submerged in water inside a container, and sunlight powers the device to free the hydrogen. HyperSolar claims that its process is more efficient and cost effective than other methods used to produce hydrogen from water. See some demonstrations in the videos below and learn more at HyperSolar's website. Eva Hakansson drove the KillaJoule electric motorcycle to a top speed of 270.224 miles per hour. After a computer model showed a possibility of about 270 mph, the team took the motorcycle with sidecar out to the salt flats for Mike Cook's Shootout. Everything went smoothly, and Hakansson easily surpassed speeds of the 249.1-mph world record she set a few weeks ago. The team is calling it quits for the season, but will make some tweaks to the KillaJoule in hopes of getting 300 mph out of the red bullet next year.

The 2016 Spanish Grand Prix flipped all the scripts

The Monaco Formula 1 Grand Prix circuit and the Hungaroring fly the flag for processional races, yet Spain's Circuit de Catalunya is arguably as bad. Before this weekend, the pole-sitter won the race 19 times out of the last 25 years. The front row of the grid produced 23 winners in the past 25 years. The racing gods edited that script this year, when a first-lap crash and two mid-race strategy changes kept things open until the end of the 66-lap race. It started when Mercedes-AMG Petronas teammates Nico Rosberg and Lewis Hamilton took each other out on Lap 1. After Rosberg passed pole-sitter Hamilton into Turn 1, Rosberg's car slowed through Turn 3, somehow in the wrong mode. Hamilton closed in on Rosberg so quickly that once the Brit ducked inside for the pass, he couldn't back out. Rosberg, however, closed the door so suddenly that Hamilton had no choice but to drive onto the grass. When Hamilton spun, he collected Rosberg and both Mercedes' ended up in the gravel trap. The stewards deemed it a racing incident. The crash put Red Bull teammates Daniel Ricciardo and Max Verstappen in the lead, followed by Toro Rosso driver Carlos Sainz and the Ferrari duo of Sebastian Vettel and Kimi Raikkonen. Both Ferraris cleared Sainz by Lap 10, leaving 56 laps for them to haul in the Red Bulls. Ferrari loosely followed Red Bull's pit strategies. Ricciardo pitted on Laps 11 and 28, Vettel pitted on Laps 15 and 37. Verstappen pitted on Laps 12 and 35, Raikkonen pitted on Laps 13 and 36. Pirelli predicted a three-stop race as the fastest and that the medium tire could only go about 23 laps. Verstappen and Raikkonen didn't get those memos. So while Ricciardo and Vettel came in for third stops the Dutchman and the Finn stayed out, with Verstappen ahead of Raikkonen at the front of the race as of Lap 43. That's when Verstappen – 18 years and 227 days old – proved how good a driver he is, lapping perfectly as second-place Raikkonen closed the gap to a little more than half a second. The Finn still couldn't get past the Dutchman down the pit straight even with the help of DRS, nor under braking at the only real passing opportunity into Turn 1. At the end of Lap 66 Verstappen crossed the line ahead of Raikkonen, a victorious end to Verstappen's first race weekend after being promoted to Red Bull. Further back, Vettel and Ricciardo fought for scraps, the German staying ahead to finish third.
