Abstract
An off-road utility vehicle includes a frame, an engine, a continuously variable transmission, a transaxle comprising a rear differential, an intermediate drive assembly comprising an intermediate differential, and a front drive assembly comprising a front differential. The intermediate drive assembly and transaxle are coupled via an intermediate driveshaft and the front drive assembly and the intermediate drive assembly are coupled via a front drive shaft. The front drive shaft and the intermediate drive shaft are counter rotating.

An off-road utility vehicle comprising:
- a frame;
- an engine;
- a continuously variable transmission;
- a transaxle comprising a rear differential;
- an intermediate drive assembly comprising an intermediate differential;
- and
- a front drive assembly comprising a front differential, wherein the intermediate drive assembly and transaxle are coupled via an intermediate driveshaft and the front drive assembly and the intermediate drive assembly are coupled via a front drive shaft, wherein the front drive shaft and the intermediate driveshaft are inline and counter rotating, wherein the intermediate drive assembly is selectively engaged to communicate motive force received from the intermediate driveshaft to intermediate axles coupled to the intermediate differential, wherein the front drive assembly is selectively engaged to communicate motive force received from the front drive shaft to front axles coupled to the front differential, wherein in a first mode motive force developed by the engine is provided only to the transaxle and the rear differential, wherein in a second mode motive force developed by the engine is provided to the transaxle and the rear differential and to the intermediate drive assembly and the intermediate differential, wherein in a third mode motive force developed by the engine is provided to the transaxle and corresponding rear differential, the intermediate drive assembly and corresponding intermediate differential, and the front drive assembly and corresponding front differential.
