Abstract: A vehicle has two axially opposed driven wheels which are driven by two drive shafts of equal length, each flexibly drivingly coupled at its outer end to one of the wheels. A differential, which has a preferred power output line, is located closer to a first one of the wheels and further from the other wheel. A short power output shaft extends from the differential towards the first wheel and is flexibly drivingly coupled at its outer end to the inner end of the drive shaft which drives that first wheel. A long power output shaft extends from the differential towards the other wheel and is flexibly coupled at its outer end to the inner end of the other one of the drive shafts, whose outer end is drivingly coupled to that other wheel. The inner race of a bearing supports an outer part of the long power output shaft, remote from the differential, and an outer race rotatably supports the inner race.
