It ran in a narrow rpm range, about 50 to 300, and therefore had limited use.

With this type of system, you would get maximum engine performance at every rpm range.

This, from a motor with a "base speed" in the 1,100 rpm range.

These engines were designed to be smooth and hold a high torque across the rpm range.

It had some problems in holding revs steady at the bottom end of the rpm range.

This allows models without the limited rpm range to remain within the car's power band throughout the gears.

The 2nd unit was on standby until the upper half of the rpm range during full throttle acceleration.

These changes cause peak torque to occur at a lower engine speed and provide better throttle response in the 3,000 to 6,000 rpm range.

It is similar to the high-performance LS6, but with improved torque throughout the rpm range.

If the prime mover is unable to produce enough power to fully drive the generator, speed will remain somewhere between 1800 and 1860 rpm range.
