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.

Mercedes to roll out C63 AMG late in 2014 with 4.0L V8

The new 2014 Mercedes-Benz C-Class is upon us, launching initially in North America with turbocharged four-cylinder C300 4Matic and six-cylinder C400 4Matic flavors. But that's only the tip of the proverbial iceberg when it comes to the vast array of powertrain configurations that will be offered in the new C-Class in markets around the world. Orders will soon be rolling in for gasoline, hybrid and diesel engines with four, six or eight cylinders, driving the rear wheels or all four, with the seven-speed automatic transmission soon to be replaced by a new nine-speed unit. But what enthusiasts are really looking forward to is the next C63 AMG.
As BMW has done with the M3 (and new M4), Mercedes has gradually ratcheted up the cylinder count in its AMG C-Class, graduating from the 3.6-liter V6 in the original C36 AMG to the 4.3-liter V8 in the C43 AMG, then the 5.5-liter V8 in the C55 AMG before going the distance with the sublime 6.2-liter V8 in the C63 AMG. Like its rivals, Mercedes is expected to use turbochargers as a replacement for displacement in the next model, but unlike its Bavarian rival, it won't be losing any cylinders in the process.
Skipping the 5.5-liter twin-turbo V8 that has gone on to power other AMG models, the next C63 AMG is still expected to introduce a new 4.0-liter twin-turbo V8 producing between 450 and 500 horsepower. It'll also reportedly keep the same seven-speed automatic transmission (instead of switching to the new nine-speed), but the jury's still out on whether it'll come with rear- or all-wheel drive (or offer buyers the choice). The downsized V8 - codenamed M177 - is then expected to find its way into other models, but the C-Class will be the first to get it when it arrives before the end of the new year ahead.
