Have you ever looked at your 577 hp/900 Nm Mercedes-AMG S 63 Coupé and thought, “I wish it made more power?” Well, Renntech has come to the rescue with tuned version of the brutish super coupé, which promises a considerable hike in output.
How much? Try 708 hp and an astonishing 1,138 Nm of torque from the 5.5 litre twin-turbocharged V8. The increase in power and torque comes courtesy of a tweaked ECU that takes it up to 669 hp and 995 Nm, as well as exhaust downpipes with freer-flowing 200-cell catalytic converters that add another 10 hp and 20 Nm. Sport mufflers with electronic valves complete the package.
Even on the dynamometer, the Renntech makes 588 hp and 945 Nm at the wheels, compared to 445 hp and 663 Nm coaxed from the regular S 63. There are no documented changes to the drivetrain, so the Renntech should channel all its power and torque through the standard seven-speed AMG Speedshift MCT automatic transmission.
Despite the significantly more powerful engine, the Renntech S 63 doesn’t shout its performance credentials through its styling – instead of a massive bodykit, the firm’s visual alterations are limited to a prototype bootlid spoiler. The car seen here is also dressed up in matte grey paint, blacked-out badging and black wheels for a more sinister appearance.
Pricing for the Renntech kit is US$3,495 (RM14,200) for the tuned ECU, as well as US$4,940 (RM20,100) for the downpipes and catalytic converter. Those seem like pricey additions, but they’re dwarfed by the cost of the actual car – a staggering RM1,493,888.

When will the day Rentech, Carlson, Brabus, Alpina, AMG will offer to tune our Proton? Our Ministers already said our Protons are BETTER than Volvo and BMW, so, its about time, the Proton also gets tuned.
I hope Putrajaya or MITI will write to Alpina to tune our Protons up. Protons are Better than BMW
