An otherwise bone stock, tune only 2012 Mercedes E 63 ran an incredible 11.15 @ 126.7 mph quarter mile this past weekend at Palm Beach International Raceway. The E63 dynoyed an impressive 578.33 horsepower and 621.93 ft/lbs of torque at the wheels (680 horsepower and 732 ft-lbs of torque at the crank) with the RENNtech tune installed. That is a 100 horsepower gain over stock!

The run was made with the stock exhaust, stock wheels and OEM street tires in 80 degree temps with damp track conditions. Needless to say, we expect quite a bit more out of the new biturbo E63 and will certainly be breaking into the 10's very shortly.

Stay tuned as we continue to push the performance of Mercedes latest powerhouse.

Here is video of the run:

 

Wow that's really impressive for just a tune! What does the renntech sl65 black series does with the 805hp package?

 

Nice numbers!

How much boost is this car running vs stock?

 

Impressive!

 

the trap speed is insane for such car!

 

That's crazy, fantastic move by MB to ditch the NA V8 and go to the bi-turbo.

 

Very nice runs.

 

That is awesome! Great work guys! Just think about the c63 with this new engine? Def 10sec material!
