Mercedes-Benz M116 engine

The Mercedes-Benz M116 is a V8 petrol engine made in several versions by Mercedes-Benz between 1969 and 1991. Every version used a single overhead camshaft with two valves per cylinder and Bosch Jetronic fuel injection. The first, the 3.5 litre M116.980, appeared in August 1969 in the 300 SEL 3.5, where 200 PS was enough for a top speed of 205 km/h, and it was followed by a 3.8 litre version in 1979 and a 4.2 litre version for the revised S-Class in 1986. Early 3.8 litre engines with a single-row timing chain suffered chain failures, which the company repaired free of charge before moving to a double-row chain. The M119 replaced the 4.2 litre engine in 1991, and the two share no parts.
