Mercedes W123 Engines and Transmissions

A Mercedes W123 engine can be gasoline or diesel, and the transmission and drivetrain shape how you drive. The 2.3 MT4 and 2.3 MT5 Coupes use petrol with a manual and rear-wheel drive; the 2.2 AT Sedan is a diesel automatic. These powertrains are examples, not every version.
