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 W213 – E63 S AMG 4MATIC+ 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!
