Designed for fast intercontinental cruising, the Mercedes-AMG GT 63 S is a true surface-to-surface long-range missile. It boasts more power than some of the most coveted supercars of the previous generation, and can easily put most of them in the corner.
But you already knew that, as the four-door beast has been subjected to countless reviews and all sorts of tests ever since it came out one and a half years ago (my, how time flies!). As for the video that you’re about to see, it also highlights the speed factor, albeit with a twist, because this is not a stock example.
German tuner PerformMaster has updated the 4.0-liter, twin-turbo V8, giving it an extra 101 PS (100 hp / 74 kW) and 130 Nm (96 lb-ft) of torque. That’s a whopping 740 PS (730 HP / 544 kW) and 1,030 Nm (760 lb-ft) of torque, which has shaved the 0-100 km/h (0-62 mph) by 0.3 seconds, to 2.9 seconds, while also lifting the top speed from 315 to 340 km/h (196-211 mph). A discreet visual makeover, with TUV approval, has further enhanced its character.
In theory, the tuned GT 63 S is as quick as the Lamborghini Aventador S to 100 km/h (62 mph), while coming just 10 km/h (6 mph) shy of its top speed. But what about in practice? The answer comes in the following video that shows the German four-door supercar doing several runs on the Autobahn and having the times recorded by a third-party device.
