What is the Difference Between Longitudinal and Transverse Engine Layouts in Cars?
1 Answers
Here are the differences between transverse and longitudinal engine layouts in cars: Engine and Transmission Placement Direction: A transverse engine is mounted horizontally, requiring the transmission to also be placed horizontally side by side; a longitudinal engine is mounted vertically, with the transmission positioned behind the engine. Power Output Direction: The power transmission direction of a transverse engine is typically perpendicular to the car's forward motion, transferring power horizontally into the transmission and then directly to the half-shafts; the power transmission direction of a longitudinal engine is parallel to the car's forward motion, transferring power rearward into the transmission, which then continues to transmit power longitudinally rearward, usually connecting to a central driveshaft for direct rearward power delivery. Car Drivetrain Configuration: Transverse engines are typically used in front-engine, front-wheel-drive (FF) layouts; longitudinal engines are typically used in front-engine, rear-wheel-drive (FR) layouts.
