Petrol 8-cylinder V-engines E420, E430, E50AMG, E55AMG (Mercedes-Benz E-Class W210)

The injection system of the 4.2-litre V8 engine has been adapted to the HFM control system. The injection and ignition functions are now combined in the Motronic 1.0 engine control unit. The electronic control system of the new automatic transmission, which has been fitted to the E 420 since launch, is integrated with the engine management system.

The E 430 model replaced the E 420. The new 4.3-liter unit belongs to the M 113 engine series. It was developed together with the V-shaped 6-cylinder engines of the M 112 series. The E 420 and E 430 engines have the same innovative solutions: 3 valves per cylinder, two spark plugs per cylinder, cylinder block liners with a low friction coefficient. The units are manufactured at the engine plant in Bad Cannstatt.

In January 1996, the E-Class model range was expanded with the sports version E 50 AMG. This is an 8-cylinder V-shaped engine with a displacement of 5 liters and a power of 347 hp, built by the AMG studio on the basis of the 4.2 liter engine. Subsequently, the E 50 AMG model was replaced by the E 55 AMG engine with a displacement of 5.5 liters and a power of 354 hp, belonging to the M 113 series.
