Väth V63RS latest tuning option for AMG fans

There's no shortage of Mercedes-Benz tuners, and we're used to having news tips in our email box regarding BRABUS, Kleemann, Lorinser, Carlsson, etc. That's why we were curious when we received a tip about a company taht we'd never heard of called Väth. The German aftermarket company has products for the entire Mercedes-Benz lineup, the latest of which is the V63RS Clubsport based on the C63 AMG that you see here. Väth essentially leaves the exterior untouched and focuses on the performance including an upgrade of the V8 to 585 bhp and 509 lb-ft torque that will power the car to a top speed of 202 mph. Other upgrades available include a sport suspension, high performance brakes, 19-inch wheels, and sport seats. Complete cars are available at a hefty 125,000 Euros, although components can be purchased individually, as well. Just like the BRABUS Bullit Black Arrow we showed yesterday, black seems to be the color of choice.

Spy shots: 2009 Mercedes CLK

The 2009 Mercedes CLK has been spotted out on the roads, getting ready for its debut at October's Paris Motor Show. The lines, cladding, and peeking swage lines would appear to indicate that it will indeed look quite a bit like recent renderings. If the flowing glasshouse is to be believed, the car will sport only the merest flick of a trunk.

Presafe braking, night vision, and the updated COMAND system will mark some of the interior changes. Engines will run along C-Class lines, but the CLK 63AMG will get a bump of six HP to 481. We would like to know, though, if the seriously low profile rubber is just for the mule. The current, softer CLK has managed to mostly avoid the worst wheel transgressions, but this harder version seems like it will be a much more popular candidate for the stop, drop, and roll routine. We'll find out in a few months in Paris.

New York 2008: Mercedes burns oil and rubber

Just like any good political campaign, Mercedes came to the New York Auto Show touting nothing much as a whole lot. Actually, the faux political rally might have been less than compelling with its old news, but the new M Class sporting 50-state legal BlueTec diesel power is exciting. Almost as exciting as the very original 1965 190 D Mercedes had borrowed to illustrate its long-running experience with Rudy's coal dust motor. The senescent sedan will be helping MBZ recreate Bill Carroll's cross-country diesel-fueled journey to celebrate the U.S.-wide availability of what it's touting as the cleanest diesel ever. BlueTec allows the M-, GL- and R-class oil burners to earn ULEV and TierII/Bin 5 classification.

Mercedes says its new diesels are now as clean as gasoline powerplants, and once they drop BlueTec hybrids on us, emissions and economy will improve yet again. JD Power projects that fully 40 percent of vehicles will be diesel powered by 2017, and Mercedes wants to increase diesel sales beyond the current level of 22 percent. The newly tweaked M-Class should help move the powertrain off dealer lots. Sporting plenty of safety upgrades, new headlights, a Hannibal-Lechter inspired grille and some interior tweaks, the M-Class has returned from the gym freshly chiseled. It was not all utes and politely obscured minivans (*ahem* R-Class). Just before Mercedes wrapped the presser, they said, we're paraphrasing here, "Oh yeah, we also brought the SL, w00t."

ZF modifies 8-speed tranny, now stop/start approved

In the name of increased efficiency, and quite possibly playing the game of automotive one-upmanship, luxury automakers such as Mercedes Benz, BMW and Lexus have been adding more and more gear ratios to their automatic transmissions. By allowing a computer to choose the most appropriate ratio for any given scenario, the vehicle's engine is required to only make as much power as absolutely necessary, potentially saving fuel in the process. ZF, one of the largest transmission makers in the world, claims that their new 8-speed unit boasts an efficiency increase of eleven percent over its older 6-speed unit. The transmission giant has just developed a new modification, though, which could increase the overall vehicle efficiency even further. By adding a hydraulic impulse storage unit, the new ZF unit can support stop/start functionality, which they claim can result in an additional five percent reduction in fuel consumption.
