Independent 1/4 mile acceleration numbers for the new R172 SLK55 AMG with the M152 5.5 liter V8 - 12.5@112
The new R172 SLK55 AMG is a pretty quick little car. Unfortunately, Mercedes-Benz would not give it the M157 Twin Turbo V8 (if they did this car would annihilate) everything else in the lineup) but the naturally aspirated M152 5.5 liter V8 is proving to be quite potent in the fairly lightweight Benz. Independent numbers from an SLK55 at the Dallas Raceway drag strip show a result of email@example.com in the 1/4 mile with density altitude of just about 0.
This puts the car on a level of acceleration close to the E92 M3 and non-P31 C63 AMG. Not bad at all and about where it should be considering its stock output 362 rear wheel horsepower. Also consider this time was run on street tires, 100% stock, with only ~700 miles on the clock. With some modifications these cars and motors will become fairly potent.
