straight engine

Non-V motor configuration

A straight engine, also called an inline engine, arranges its cylinders in a single row along the crankshaft rather than in a V-shape or opposing configuration.

This layout offers mechanical simplicity and smooth operation, particularly in four-cylinder and six-cylinder designs.

Straight engines are common in everyday passenger vehicles, while the straight-six configuration is prized in performance and luxury cars for its inherent balance.

The old BMW had a silky-smooth straight-six under the hood.
