Frankfurt Auto Show Preview: Lotus Range-Extender Engine
There is a line being drawn in the sand between two-different types of hybrid cars. There are those that follow the model of the Toyota Prius and Ford Escape hybrid, which alternately use electric and gas power. Then there are those like the Volt which uses electric motors to drive the wheels while getting electricity from a small gas motor.
Lotus has developed a “range-extender engine” that falls into the latter catagory. It implements numerous money and weight saving features that could make extended-range hybrids even more appealing in the future.
