The five-cylinder in- line engine with a bore of 82.5 mm and a stroke of 92.5 mm has a compression ratio of 10: 1. The valve is controlled via a control chain .
EA855 evo (since 2015)
One of the main differences between the EA855 and the EA855 evo is the weight. While a gray cast iron engine block was used in the EA855, an aluminum alloy is used in the EA855 evo . The weight of the stainless steel crankshaft has also been optimized by reducing the diameter from 58 mm to 52 mm. Further changes were made to the pistons , connecting rods and the oil pan to save weight. This reduces the weight by 26 kg.
