SLS Vs. 458 Matchup Raises A Few Questions  阅读原文»

If you've still got any doubt that the Mercedes SLS AMG is a supercar, if not an exotic, then take a look at this video of Mercedes-AMG's hellion matched up against a Ferrari 458. On paper, the engines of the two cars are pretty much even, both being highly-tuned V8s, and being a couple of horsepower shy of 565 stallions. However, the stats will show that the Ferrari is about 250 pounds lighter than the SLS AMG. That's the equivalent of one or two passengers.

Which makes it a bit of a surprise why the Ferrari doesn't get a big jump on the SLS on the acceleration runs. Torque and gearing would play a part. As would the supposedly better drivetrain efficiency of the SLS, which enables it to put out more rear-wheel horsepower to the driven wheels. So is Ferrari overstating the 458′s output? Or is AMG being coy about what its engine really makes?

Tuner CK63 RS Coaxes 640 Hp From Twin Turbo V8  阅读原文»

Slowing its rise only when it reaches 260 kilometers per hour, this Carlsson-tuned CLS 63 AMG shows the potential of Mercedes’ a tuned twin turbo V8. Known as the type M157, this engine is a refinement by AMG of what was originally the M278 engine developed for the S-Class. After extensive modification by AMG, this engine got the M157 designation.

When an outside tuner like Carlsson is able to extract 640 horsepower from an engine already tuned by AMG to 560 hp, one wonders about the degree of conservatism that the factory tuners built into their work.

Seeing the into to the video of how the CK63 RS absolutely lays waste to its tires gives you an indication of how much power is on tap. Inside the car, there is almost no sense of the drama taking place outside and in the engine room, but the way the speedometer walks up the speedometer gives a pretty clear indication of the forces that occupants will undergo.
