    Abstract: A vehicle drive assembly includes an electric motor directly coupled to a rotatable member for driving a wheel, for example, without gear reduction assemblies between the motor output and the driven wheels. A multi-phase, high pulse current stepper motor is used as the motor in one example. A driven wheel is supported by a wheel mounting member in a conventional fashion. A rotatable member associated with the wheel mounting member is directly coupled to an output of the stepper motor. The stepper motor can selectively operate in several modes. A first mode provides driving torque to the vehicle wheels, a second mode provides a braking force and an optional third mode allows the stepper motor to serve as a parking brake.

    Abstract: An exhaust processor comprises a Helmholtz resonance chamber with a variable tuning throat. The tuning frequency of the exhaust processor changes as the outlet opening from the variable tuning throat into the Helmholtz resonance chamber changes.
