The 700 HP RennTech CLS63 AMG – /TUNED

Hartmut Feyhl left AMG after 15 years to start his own tuning company, RennTech, which is now one of the most respected AMG tuners in the world. His products range from simple software upgrades to full racing builds based on AMG street cars. We take his new, 700 horsepower CLS63 for a spin and establish a new benchmark for luxury sedans: must be able to do burnouts while moving at highway speeds.

Mike G says:

U don’t want merc to go back and make manual again it will be a problem it will destroy any car

K. B says:

what is the point of having 700 HP when you only have 600 at the wheels?

Jah Cousteauu says:

+Rock, i agree that it is not worth it.I’m thinking of either going with tthe e350 coupe because it comes with an awd. In 2012 and then doing an engine swap with an e63 amg engine to get the V8 power plant as a starting point and base to modify or……… just switch to an Infiniti ,G37s with the awd in the coupe of course and add some Bigg Twin Turbos going for an output of at least 520 hp to the ground. Im just not sure if I’m going to modify both coupes yet. I test drove the G37s this past week and didn’t love it but im use to driving the e550 …. so the V6 G37s wasn’t good enough for me…but with the 300+ hp increase. Plus torque and an air suspension upgrade -complete with rims, tires, and brakes…. it should be awesome.

Anybody know the song name?

Punisher says:

Nice Car, not $120k nice..

Nick Dodenc says:

That’s serious power, a car that heavy spinning tires at 40mph it really is something special imagine what the finish product would be?

Surprising BMW always was more sporty then Mercedes Benz although they have clearly peeled off with that crown wtg Benz

CHIPZ711500 says:

4:12 THAT SOUND…..excuse me i must go change

Steve Back says:

Awesome car. The only down side will be that this car will be the death of those who under estimate the power of this car. When the driver wrecks the body will be unidentifiable without a doubt. All buyers please respect your life and the lives of other drivers!

Christian Rasmus says:

Lus Amarii says:

Who knows how to set the lights to be switched on in the headlights and daylight ?
I do not want daylight and beam.
I want to be on daylight at the bottom and those LEDs in the headlights.
Thank you.

OPHeckler says:

Oh god you can hear his saxonian dialect even in english

Zach T says:

Who the hell wants a car that gets to 10mph in 10 seconds because the tires spin for days. That is way too much power it’s insanely impractical. Gonna swap those tires every 2k miles if you use all of the horses. Stupid.

Kayne's World says:

I love the sound of AMG’s even stock they sound like they just want to go.

Jah Cousteauu says:

i want RennTECH to tune my E550, they don’t make a AMG in the e-class, and i wanted one in my coupe…. i need 550hp “To the GROUND”…YESSSS!!!
