One of the first hybrids was based on a 42 series B&S Opposed engine

This Crazy Six-Wheel Hatchback by Briggs & Stratton Was One of America's Fist Hybrids

Introduced in 1980, it could run 40 to 60 miles (64-96 km) on electric power and when its twin-cylinder kicked in, this six-wheeler could reach 68 mph (109 kph)

To do that, the company's engineers equipped it with an air-cooled and carburated flat-twin engine rated at only 18 hp.

Recharge from a the grid, unless you’re driving long distance, at which point the turbine fires up to charge the batteries. Regenerative braking on the electric motor. The turbine offers fuel flexibility. It will run on about anything. Simple engine. Way too much power!

1975. Nearly 50 years later, sadly, the world has only produced cars with elements of this great idea.

The Persistent Contender: PopSci Covers the Hybrids

Hybrid gasoline-electric vehicles began appearing late in the 19th century from manufacturers such as the Compagnie Parisienne des Voitures Electriques in France. In this country, an engineer named H. Piper applied for a patent on a gasoline-electric motor combination on Nov. 23, 1905. By the...
