Engine Mercedes M103 E30

Released in 1985, the inline six-cylinder M103 E30 engine was intended to replace the outdated M110 engine in all respects and was partially unified with the four-cylinder M102 2l. The next M103 series (which also included the 2.6-liter M103 E26) received a new lightweight cast iron cylinder block and a 12-valve block head with one camshaft and hydraulic lifters, instead of the previous 24-valve two-shaft, which was due to the desire to increase efficiency, reduce power plant weight and production costs.
