Mercedes-AMG makes some of the best engines in the world. Each is hand built under the one man one engine philosophy, but which is best? The 2.0-litre Turbo in the A45 AMG, the 4.0-litre bi-turbo V8 in the C63 AMG and AMG GT, the 5.5-litre bi-turbo V8 in the GLE 63 or the 6.0-litre bi-turbo V12 in the S65 AMG Coupe? Or maybe the 3.0-litre V6 turbo in the SLC 43? In this video I compare each engine’s tyre-sheering torque, the noise they make and their outright horsepower in a standing quarter mille drag race. Sit back and enjoy the ride – the result may shock you.
