It's currently the ninth fastest production car to lap the N?rburgring, so not many people would argue that the Mercedes-AMG GT R needs more power. But that hasn't stopped the folks over at Edo Competition from extracting yet more grunt from the German supercar.
Edo Competition has increased the M178 twin-turbo 4,0-litre V8 engine's outputs to 492 kW and 780 N.m (from 430 kW and 700 N.m), chiefly by means of increasing the boost pressure.
As a result, the tuner says its fettled GT R can now reach a top speed of "well over 340 km/h". The new 0-100 km/h time has not been revealed, but it?s sure to be a touch quicker than the standard model?s claimed time of 3,6 seconds.
The Ahlen-based company furthermore revised the GT R?s chassis, lowering the front by 25 mm and the rear by 20 mm. To add some aural drama (and flexibility), the German monster has also been fitted with adjustable exhaust flaps.
