Earlier this year, Fostla presented their take on the Mercedes-AMG GT S, which came with a neck-snapping 613 PS (604 hp / 451 kW) and 768 Nm (566 lb-ft) of torque.

Now, they have an even more impressive power upgrade available for Affalterbach’s sports car. It’s aptly called Level 2 and includes some more ECU tuning, in addition to the upgraded downpipes by PP-Performance and BMC sports air filter, which result in an output of 650 PS (641 hp / 478 kW) and 800 Nm (590 lb-ft) of torque.

Unfortunately, the Hannover-based tuning company doesn’t say how fast their Mercedes-AMG GT S is in this form, but it’s probably very close to 3 seconds for the 0-62 mph (0-100 km/h) sprint, given that the stock model, whose twin-turbo V8 makes 510 PS (503 HP), takes 3.8 seconds.

Adorning the exterior of the car is an aerodynamic body kit, made together with Prior Design. And for a deeper effect, Fostla has applied a vinyl wrap in a shade called Malachite Green and added a KW coilover suspension and 20-inch ADV.1 alloys. A total of 50 units will be produced in this specification, and all of them are destined for Europe.
