2012 Mercedes CLS 63 AMG by Renntech

The recently launched Mercedes CLS 63 AMG is powered by a 5.5-liter biturbo V8 engine that delivers a total of 518 HP and 516 lb.-ft. of torque - a very impressive output for a luxury sedan, no doubt. That being said, American tuner, Renntech, has found a way to further improve the final output of the car to an impressive 669 HP and 734 lb-ft of torque.

According to the first details offered by the tuner, this is just the Stage 1 upgrade for the CLS63 AMG. In this stage, the extra output is provided by the addition of ECU tuning software and a new exhaust system. This allows the Mercedes to sprint from 0-60 mph in 3.4 seconds at a speed of 125.01 mph. Better yet, it recently took on a Nissan GT-R at the Palm Beach International Raceway where it achieved a quarter mile in 11.21 seconds at 126 mph.

The total price for this package is $3,495.

Hit the jump to watch the Renntech CLS 63 AMG in action next to the Nissan GT-R.


It looks great on the video. An impressive output of 669HP makes me drool on that car.

@Lala_Roux It definitely looks classy and elegant. What car do you have in your garage?

This car is already good per se, but Renntech’s tuning obviously made it better. I personally like the modification of its exterior.

Renntech has effectively applied their automotive knowledge on this; there was no aspect left untouched.

Renntech has strengthened the sporty aspect of this car, although it didn’t lose its elegance.

It’s not the only model that Mercedes has produced, which is either luxurious and sporty. The thing is, I think this one’s the most popular among them all because of Renntech’s tuning.

I’m totally amazed by how this luxurious car can run with a boosting speed. It’s like classically designed, but its engine is athletically challenged. You know what I find attractive the most? Its tail lights and exhaust pipes.

Its biturbo V8 engine is really impressive for this luxury sedan! Well, I will surely wait for this one, and I would truly hope that it also has a stunning and interesting interior.

I hope that they already include its interior. Anyway, I will surely wait for an updated news about this vehicle. Moreover, just like them, I’m so impressed either with its powerful and efficient engine.

I’m truly impressed with the powerful engine of this vehicle, which gives me an idea that it is so fun to drive with on that output. Moreover, I must say that the exterior appearance of this vehicle is really very irresistible.

It looks classy and elegant on its exterior detailing especially on its sleek body paint. It’s also great with its very impressive engine, which gives me an idea that this vehicle is so fun to drive with!

CLS 63 AMG looks very perfect on every angle of it. Its sleek body paint only adds more appeal on this one. Good thing as well that it has an impressive engine output of 669 hp!
