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.

2014 Mercedes-Benz SLS AMG Black Series [w/video]

The biggest misconception about the Mercedes-Benz SLS AMG Black Series is that it's simply a higher-performing version of the SLS GT - a closer look, or better yet, a few hot laps on a high-speed racing circuit, reveals that is anything but the case.
Launched in the States in mid-2011, the standard SLS GT is a 583-horsepower, all-aluminum, gull-wing coupe with performance that positions it near the top of the exotic segment. While the AMG team at Mercedes-Benz could have left it alone, their experience with the SLS AMG GT3 race car said there was room for improvement, so they devised the SLS Black Series. The transformation from SLS GT to SLS Black Series is extensive, with no fewer than 17 different significant enhancements.
The engine mapping, crankshaft, connecting rods, valve-train, intake, exhaust and cooling are all modified and the engine's redline bumps up from 7,200 to 8,000 rpm, which pushes output of the hand-built 6.3-liter V8 to 622 horsepower. The power steering receives a new ratio, a coil-over AMG Adaptive Performance suspension is installed along with underbody braces, the track is widened, two-piece carbon-ceramic brakes replace iron rotors at each corner and a lightweight titanium exhaust is fitted beneath. The AMG Speedshift seven-speed dual-clutch gearbox is modified and an electronically controlled AMG rear differential lock ensures the power goes to the pavement. Last on the mechanical upgrades are new lightweight forged wheels (10x19 inches front and 12x20 inches rear) wrapped in special R-compound Michelin Pilot Sport Cup tires.

Next Aston Vantage will be the only way to get an AMG V8 with a stick

With only a few exceptions, most of them factory customs, AMG hasn't built cars with manual transmissions. It just isn't the way things are done in Affalterbach. But now that Mercedes's in-house speed shop will be supplying engines to Aston Martin, the world will be treated to cars with three pedals and overengineered German V8s wrapped in a pretty British package. We're into it. The news comes from Car and Driver, which spoke to Aston Martin CEO Andy Palmer about the new Vantage among other things. Palmer confirms to C/D that the Vantage will continue to offer manual and automatic transmissions when the next-gen car arrives featuring the AMG 4.0-liter twin-turbo V8. In its most potent form, the eight-cylinder makes 503 horsepower and 479 lb-ft of torque in the AMG GT S. Figure on a little more from the Aston-ized version, just for fun. The current V8 Vantage GT makes 430 hp and 361 lb-ft from its naturally aspirated 4.7-liter. While some may lament the new engine's forced induction, that added power and the thoroughly modern behavior of the AMG engine should be welcome. While the AMG V8 is currently only planned to go into Aston's entry-level car, C/D does mention a possibility of it (and perhaps its three-pedal transmission) making its way into other cars as an economy option for certain markets. If a V8 DB11 were to be offered, don't expect it to show up here, though. There's also no word on who will supply the manual for the AMG-Aston mashup, but it likely will be a transaxle like the current Vantage. Ex-factory manual AMGs aren't totally unprecedented. Pagani has built some three-pedal cars with its massaged AMG V12s. Compared to those, however, these manual Vantages can be considered mass-production cars. And really, any increase in the number of sticks mated to AMG engines can only be a good thing.
