The motor features a twin scroll turbocharger. The intercooling system is an air/water setup and fairly compact. The direct injection system comes over from the other AMG direct injection motors which hopefully means it has fueling headroom as that usually is the area that becomes problematic when tuning direct injected motors.
Peak torque is achieved at about 2250 rpm so for a motor with this much power there is not quite as much lag as one would expect considering its size. The motor holds this torque to around 5000 rpm. Peak power is hit at 6000 rpm and the redline is 6700 rpm.
Interesting to not is that the compression ratio for a direct injected motor is a very low 8.6:1 which likely is what allows 26 psi on pump gas. Still, a very low compression ratio for a modern turbo motor and an interesting design choice by AMG.
The transmission can send up to 100% of the power to the front wheels and 50% to the rear wheels depending on traction. Impressive? You bet.
