The drive assembly includes one or more motors driving at least a pair of continuously variable ratio transmission devices which each drive a driving wheel or driving axle of the vehicle. The methods enhances driver’s convenience and safety in the event of back-in perpendicular parking. The gas generator includes a housing with a plurality anode and cathode electrode plates. Railing members each slide through adjacent pairs of insert members to form a wall of spaced apart railing members. The inventive design allows for a simple maintenance and production of the dosing device. At least one compressor exit stator shroud is welded to the intermediate case.
