Vehicles with these systems are becoming known as "minihybrids" or "mild hybrids."

In mild hybrids, the electric motor plays a more limited role.

The first vehicle was built in a series hybrid configuration, while the next two were considered mild hybrids.

With an EPA fuel-economy range of 41 city/36 highway, this is no "mild hybrid."

This engine is due to return for 2012, but in "mild hybrid" form--which should be even more fuel efficient.

The Hondas are "mild hybrids," because they use their gas engines, to some extent, at all times.

The system works like a "mild" hybrid in that it can shut off the gasoline engine at a stop.

There is no standard terminology for such vehicles, although they may be termed mild hybrids.

And that is where even a mild hybrid makes a difference.

These mild hybrids did not use electrical energy for propulsion, like GM's later designs.
