ABSTRACT:
An automotive vehicle having improved fuel economy is equipped with a drive system having a primary internal combustion engine and an auxiliary internal combustion engine of smaller size and better fuel economy than the primary engine. The primary engine is adapted to take the vehicle to its cruising speed, at which point the auxiliary engine is activated and interacts by way of an automatic clutch system to power the vehicle while the primary engine is disconnected from the drive system and throttled down.
