RENNtech SHATTERS ANOTHER WORLD RECORD | Supercar in Sedan’s Clothing RENNtech E63 S AMG

RENNtech’s first shot at improving the spectacular Mercedes AMG E-Class took the impressive Sports-Sedan to the next level with ONLY  ECU (Engine Control Unit) software tuning.

Delivered from the factory in Affalterbach with over 600 HP the AMG E63 goes from 0-60 in 3.3 seconds.    

With the upgraded software, RENNtech was able to gain more than 80 HP and 80 LB-FT over stock to bring the power of the 4.0L V8 Twin-Scroll BiTurbocharged engine up to 773 HP and 778 LB-FT.

With ECU alone RENNtech was able to break the record for the world’s fastest street legal E63 AMG in the 1/4mile in 10.685 seconds @ 130 mph. The RENNtech E63 is now able to go from 0-60 mph in 2.79 seconds and from 0-100 mph in 6.61 seconds, while doing the sprint from 60-130 mph in 8.27 seconds. All this without physically modifying engine or exhaust parts.

RENNtech set this world-record on their brand-new forged performance wheel, the RENNtech Performance Series. Developed in collaboration with Vossen Wheels, the RPS is 100% designed, engineered and manufactured in Florida, USA. Every wheel is developed specifically for one vehicle application; the wheels of the RPS are wider than stock to improve traction and still are able to reduce weight. All wheels are forged out of the highest-graded aerospace T6-6061 Aluminium.


Stay tuned for RENNtech’s future gains with the Exhaust and Turbocharger upgrades!

RENNtech has been at the forefront of ECU tuning since electronic engine management started to show up in vehicles during the mid 1980s! Our experience, countless hours of in-house research, development and exhaustive testing ensure that our proprietary ECU upgrade offers incredible performance gains and rock solid daily driver reliability.

RENNtech tuning software for Mercedes offers significant gains in horsepower and torque across the vehicle's entire power band. By modifying ignition timing and throttle mapping, optimizing air-to-fuel ratios, increasing the engine's rev limiter and modifying boost mapping for turbo-charged vehicles, RENNtech performance software unleashes the true potential of your Mercedes.
With the proprietary RENNtech ECU Tuning the W213 - E63 AMG S 4MATIC+ gains up to +82 HP and +81LB-FT, based on power numbers measured by RENNtech. Please note that the Mercedes M177 engine performance when measured, obtains higher numbers than rated from factory. The maximum power number reached with the RENNtech ECU Upgrade for the E63 AMG S 4MATIC+ is 773 HP and 778 LB-FT.

*Note: Mercedes M177 engine performance when measured on the dyno obtains higher power numbers than rated from factory. Performance numbers published by MBUSA are a calculated average within a specific rpm range, which obviously result in lower power numbers than at the peak. HP and TQ gains calculated by RENNtech are always based on peak stock results measured by RENNtech and upgraded peak results measured by RENNtech.
