Producing a combined system output of 600 kW and a tyre-shredding 1 420 N.m of torque – 450 kW/850 N.m and 150 kW/320 N.m from the internal combustion engine and electric motor, respectively – the AMG GT 63 S E Performance blasted to 100 km/h from standstill in a whip-crack 2.79 seconds – a new record for cars tested by CAR Magazine.
Indeed, although only by a small margin, the figure our test equipment recorded with this Mercedes-AMG bested what we achieved with the car – the 992-generation Porsche 911 Turbo S (2.82 seconds), which we evaluated for a road test in 2021 – that held the record as the fastest accelerating car we’ve ever tested.
In addition, the GT 63 S E Performance completed the 0-200 km/h sprint in just 8.67 seconds, before covering the quarter mile in 10.49 seconds.
The in-gear acceleration times were equally impressive, with this AMG recording 0.7, 0.93 and 1.06 seconds between the 80-100, 100-120 and 120-140 km/h increments, respectively

Touted as the fastest accelerating AMG series-production car ever created, we’ve strapped our test equipment to the Mercedes-AMG GT 63 S E Performance to see just how quick it is on our test strip.
Spearheading Mercedes-AMG’s GT lineup, the German marque unleashed the GT 63 S E Performance in April 2024, and in June 2025, this model, which the Affalterbach brand bills as the fastest accelerating production car it’s ever created, arrived in South Africa.
With a claimed 0-100 km/h sprint time of 2.8 seconds, we expected the pinnacle AMG GT to be quick. But could we manage to match – or even, best – the automaker’s claim? To find out, we strapped our RaceLogic Vbox to the (2 195 kg, tested) Hyper Blue Magno press unit and headed to our test strip.
