While 2009 was a tumultuous year for automakers, the worldwide economic crisis pushed the auto industry into the mainstream automotive media’s spotlight, making big automotive news stories even bigger. And while new products continued to be introduced, they garnered possibly even more attention that ever before. With that in mind, we thought we’d take a look back at some of the Top 10 biggest stories of 2009 for an automaker that didn’t recoil, but continued on, unveiling an all-new version of one of its most important models, delivering a new exotic car to market, promising an electric car in the future… and making some big changes in its motorsports program. That automaker is Mercedes-Benz.


#10 Mercedes Goes Green With New Hybrids

Slow to adapt hybrid technology, German automakers began to take on the Japanese luxury hybrids in 2009. Mercedes launched two important hybrid models, the S400 Hybrid and the ML450 Hybrid. The S400 Hybrid was the first Mercedes hybrid to go on sale and is also the first mass production automobile to use a lithium-ion battery. Priced at $87,950 it uses an electric motor and 3.5-liter gasoline V6 to produce 295-hp, while getting mileage of 19/26 mpg – an improvement of 26 percent over the S550 in the city. Despite its high-tech battery pack, the S400 Hybrid is a mild-hybrid, which limits its fuel economy.

The second hybrid model from Mercedes is the ML450 Hybrid 4MATIC. A lease-only model, for either 36 or 60 months, at either $659 or $549 per month, the ML450 is the first two-mode hybrid (like the Toyota Prius) from Mercedes. The ML450 uses a 3.5-liter V6 engine and two electric motors to make 335-hp and 381 ft-lbs of torque. Unlike the S400 Hybrid, it will be able to operate exclusively on electric power for short periods of time. Its fuel economy is rated at 21/24 mpg (city/highway), which is roughly the same as the ML350 Bluetec diesel at 18/25 mpg. This is also a 46 percent improvement over the fuel economy rating of the similarly-powerful ML550.

The next step for Mercedes in the field of hybrids comes with the Vision S500 Plug-In Hybrid, which debuted at the Frankfurt Auto Show and foreshadows a plug-in hybrid version of the next generation S-Class. Thanks to a direct-injection 3.5-liter V6 engine mated to a 60-hp/184 ft-lb electric motor and a lithium-ion battery pack, the car is capable of getting an amazing 73.5 mpg! Possibly more shocking is that the car doesn’t sacrifice performance, with a 0-60 mph time of 5.4 seconds. Additionally, the electric motor will be able to power the car emissions-free for 18 miles.

The Corvettes, Porsches and Vipers that compete in the SPEED World Challenge GT series are about to get some serious competition from a serious car – the Mercedes McLaren SLR 722 GT. The car was homolgated to World Challenge specs by The Racers Group (TRG) and our sources at the series tell us it will first see competition at the Autobahn County Club outside Chicago on July 24-26th.

Designed specifically to run it a spec series in Europe, the 722 GT is powered by a modified version of the supercharged 5.5-liter V8 and makes 680hp and 612 ft-lbs of torque. It also only weighs 3,200 lbs, meaning it can accelerate to 60 mph in just 3.3 seconds. Thanks to some serious aerodynamics and a significantly lowered ride height, the 722 GT is also capable of hitting 2 Gs in the corners.

No doubt the SCCA (the governing body for World Challenge) will level the playing field, forcing the SLR to either add weight or reduce horsepower… or probably both.

TRG Motorsports should still put on quite a show with the SLR as the team has plenty of racing experience, running cars in the Grand-Am Koni Challenge as well as in the Grand-Am Rolex Series. In 2005 and 2006 TRG competed with a Pontiac GTO.R team in the Grand-Am Rolex Series GT class, and has since been involved with a two-car Porsche effort in the GT Class.
