The story

Mercedes-AMG A 45 S

Mercedes-AMG revealed the A 45 S in July 2019. Its M139 engine is mounted rotated 180 degrees, with the turbo and exhaust at the back to improve airflow and shorten the front end.

AMG Torque Control uses two multi-disc clutches on the rear axle, so the car can split torque between the rear wheels as well as between the axles.
