Mercedes-Benz S63 AMG G-POWER-02

The Mercedes-Benz S 63 AMG stands out prominently as the pinnacle of the AMG range, so much so that German company G-Power – a tuning house more accustomed to tuning BMWs – couldn’t resist not having a go at it.

Inside the bay of the W222 Mercedes-Benz S 63 AMG sits an 5.5 litre V8 twin-turbo engine that produces 585 hp and an already-massive 900 Nm of torque. G-Power has managed to up that figure without the need for any modifications to the power plant.

G-Power’s invention is an external plug-and-play module called the Bi-Tronik 5 V1 ECU. It can be easily installed or removed without too much hassle and even lesser worry. Once installed, the module will give the S 63 AMG a healthy 695 hp and a total of 1,000 Nm of torque.

In its original state-of-tune, the S 63 AMG sprints from 0-100 km/h in 4.4 seconds. Installing the G-Power ECU unit allows the big limo to shave off as much as 0.6 seconds – all-in-all, it completes the century sprint in just 3.8 seconds as a result.

To top that off, the sedan’s factory-limited top speed of 250 km/h is removed, which means it can now hit a top-speed of 330 km/h. Note that all that power is only delivered to the 4Matic all-wheel drive when the driver accelerates fully – the original engine mapping will still be in effect for normal driving.

Refreshingly, no exterior work has been done to the AMG sedan save for a custom wheel option. G-Power offers ultra-lightweight Hurricane RR forged alloys made from “aerospace aluminium”. The 21-inch Jet Black wheels have a diamond cut finish. The company claims the wheels improve handling, grip and braking.

G-Power’s Bi-Tronik 5 V1 ECU module is tagged at 5,797 euros (RM27,973) while the Hurricane RR wheels will set you back 7,643 euros (RM36,902).
