FrontantriebsTransaxles

FrontantriebsTransaxles are integrated power units used in front-wheel-drive vehicles that combine the transmission and the final drive (differential) into a single assembly located at the front of the drivetrain. In most applications, the engine is mounted transversely, and the transaxle sits directly ahead of the front wheels, providing rotational power through short output shafts to the wheel hubs.

Inside a FrontantriebsTransaxle is the gear set, differential, and clutch or hydraulic torque converter, with the gear selection mechanism depending on the transmission type (manual, automatic, CVT, or DCT). Some designs place the differential at the end of the gear train; others use integrated clutches or multiple gearpaths to provide smooth shifts within a compact case.

Advantages include compact packaging, reduced drivetrain length, lower weight, and potential cost savings from fewer components compared to separate engine, gearbox, and prop-shaft arrangements. The configuration supports efficient interior packaging and can improve front-end rigidity and steering feel. Limitations include greater manufacturing complexity, noise, vibration and harshness management, and torque-handling limits at high power; AWD variants add a transfer mechanism to enable power delivery to the rear axle when required.

Applications span most compact and midsize passenger cars designed for front-wheel drive, where the transaxle is the primary drive unit. In electrified platforms, the front transaxle may be an e-axle that integrates an electric motor with reduction gearing and the differential, enabling front-wheel drive with electric propulsion.
