Leave it to Subaru to do the first horizontally opposed diesel
In a world dominated by plain-vanilla inline engines, Subaru's horizontally opposed boxer-four forges a lone path of automotive diversity. Now there's a further advance from Subaru: the world's first horizontally opposed diesel car engine. Subaru champions the boxer because of engineering fundamentals: low center of gravity for sharper handling and a lower hoodline for reduced drag. The inner workings also feature a perfect balance of the crank, connecting rods and pistons, which rotate in opposed harmony to cancel out unwanted vibrations.
