Mercedes-benz Clk-class Amg 63 on 2040-cars
Boise, Idaho, United States
There's nothing better than the sound of a big-bore V8 in the morning. That is unless you can lower the car's top at the touch of a button and enjoy it all the more, like we did in the 2007 Mercedes-Benz CLK63 AMG. The new 6.2-liter engine, designed from scratch by the powerhouse AMG division of Mercedes-Benz, features a wildly "oversquare" design; that is, the diameter of the cylinder bores (102.2mm) is larger than the stroke (94.6mm) of the pistons. In other words, you can almost distinguish each discrete explosion as the high-compression (11.3:1) engine bellows through the free-flow dual-tipped exhaust. For gearheads, it's one of those uniquely identifiable exhaust signatures that can only come from an engine of that design.The new V8 is, or will be, at the heart of several 2007 AMG-equipped offerings, and in this application, it produces 475 horsepower at 6,800 rpm, and 465 pound-feet of torque at 5,000 rpm. That represents a 30-percent and 24-percent increase over the 2006 CLK55's 5.4-liter output.Surrounding the magnificent new engine is an updated version of the CLK Cabriolet, suitably wearing new badges and bodywork, and new 18-inch wheels surrounding fade-resistant composite-construction front brakes discs. Once again, it appears that the U.S. market will not enjoy a coupe version of the CLK in AMG dress, although we drove one of those as well.Big power, big smile Our drive route comprised a healthy mix of freeway, sweeping rural highways and farm roads that showed off the engine's particularly wide-ranging abilities. Most of the time, the engine loafs around town, shifting at say, 2,000 rpm, using just about an inch or two of the throttle pedal. But that doesn't mean the car is slacking. On the contrary, even at moderate engine speeds below 4,000 rpm, the 6.2-liter V8 is more than capable of propelling the 4,100-pound car with authority. Indeed, the torque plateau begins at just over 4,000 rpm and tops at 5,000.Only when the road straightens out can a driver use all the throttle. When he does, the world goes all streaky and blurry 'round the edges as the tachometer slowly sweeps toward its rev limit just over 7,000 rpm. Speed seems to build exponentially because there are so few shifts occurring, and each gear feels like it lasts twice as long as one would expect from a seven-speed transmission. Most of that's due to the rather tall (2.65:1) final-drive ratio in the rear end, but the effect is one of limitless acceleration. Mercedes claims a 4.7-second 0-62-mph (100 km/h) time (in 2nd gear), and the shift from 3rd to 4th doesn't occur until you've surpassed 100 mph. That's some tall gearing.The car is electronically limited to a top speed of 155 mph, but doing the math reveals a real potential for just over 200 mph in 5th gear, assuming it could push that wall of air. The other byproduct is that fantastic soundtrack issuing from the tailpipes. When the conditions are right, you can actually hear spent gases rushing through the system like the great big air pump that it is.

Ecclestone wonders if F1's upcoming turbo V6s should get augmented sound [w/videos]
Mon, 08 Apr 2013While every team on the Formula One grid is worried about making a good showing in this year's championship at the same time as they develop a brand-new car for next year's championship, Bernie Ecclestone and F1 circuit promoters have a different concern: how next year's cars will sound. The current cars use 2.4-liter, naturally-aspirated V8s that can reach 18,000 revolutions per minute and employ dual exhaust, next year's engine formula calls for 1.4-liter turbocharged V6s that are capped at 15,000 rpm and are constrained to a single exhaust outlet. Ecclestone and promoters like Ron Walker believe the new engines sound like lawnmowers and that the less thrilling audio will keep people from coming to races. If Walker's Australian Grand Prix really is shelling out almost $57 million to hold the race, every ticket counts. As a fix, according to a report in Autoweek, Ecclestone "suggests that the only way to guarantee [a good sound] may be to artificially adjust the tone of the V6s."
However, neither the manufacturers nor the governing body of F1, the FIA, think there will be a problem. Ecclestone fears that if the manufacturers "don't get it right" they'll simply leave the sport, but the only three carmakers and engine builders left next year, Renault (its 2014 "power unit" is pictured), Mercedes-Benz and Ferrari are so embedded that it would stretch belief to think they'd leave the table over an audio hiccup - if said hiccup even occurs. And frankly, these issues always precede changes to engine formulas, as they did when the formula switched from V10 to V8; fans, though, are probably less focused on the engines and more on the mandated standardization of the sport and the spec-series overtones that have come with it.
No one knows yet what next year's engines will sound like, but we've assembled a few videos below to help us all start guessing. The first is an engine check on an Eighties-era John Player Special Renault with a 1.5-liter V6 turbo, after that is Ayrton Senna qualifying in 1986 in the Lotus 98T that also had a 1.5-liter V6 turbo, then you'll find a short with a manufactured range of potential V6 engine notes, and then the sound of turbocharged V6 Indycars testing last year at the Indianapolis Motor Speedway. Any, or none of them, could be Formula One's future.
First official shot of Mercedes S-Class Coupe leaks out
Mon, 10 Feb 2014With the official debut for the Mercedes-Benz S-Class Coupe expected tomorrow, it shouldn't be a surprise that some clicky fingers have already managed to uncover an official image of the car before the unveiling. Outside of this sole image, though, there's precious little detail on the new car.
First posted by Autofilou and then picked up by WorldCarFans, the production S-Class Coupe isn't far off from the concept car we saw a few months back in Frankfurt. Like the concept, the leggy production model appears related, albeit distantly, to the S-Class Sedan. The hood and front fascia are longer and lower, befitting of a two-door, while the character lines in the profile are more pronounced. Obviously, the beltline and slim, B-pillarless greenhouse are coupe-only items. We can't see any details on the back of the car, although it does appear that the long hood has a correspondingly short rear deck.
We'll have all the details on the official replacement for the CL-Class when it makes its full debut tomorrow. Until then, what do you think of this lone image? Does it appear that Mercedes has got it right? In terms of design, where would you rank this with the departing CL-Class? Have your say in Comments.
Clark Gable's 1955 Mercedes-Benz 300SL Gullwing doesn't sell, then does sell for $1.85 million [UPDATE: w/video]
Sat, 19 Jan 2013How much extra value does previous celebrity ownership add to of a car? Really, there's no way to know until the car in question hits the auction block and bidders start raising their hands. In the case of the 1955 Mercedes-Benz 300SL Gullwing you see above, the celebrity owner is none other than Clark Gable, who purchased it new. After Gable's death in 1960, the car changed hands a few times before settling with Charles Wood in 1975.
A high-dollar restoration was performed in 1989, and period accessories added by Gable himself were kept in place, including the Rudge knock-off wheels and Nardi steering wheel. Any Mercedes-Benz 300SL is worth a big chunk of money. In the case of Clark Gable's old Gullwing, the bidding stalled at $1.9 million here at the 2013 Barrett-Jackson auction in Scottsdale. As one of the 5000-series cars, this 300SL carried a reserve, and a bit of after-the-fact dealmaking saw the car change hands for $1.85 million.
You can see our high-res image gallery above, and the car's official auction description below.
