What’s one simple way to extend range on the next-gen Fisker gasoline-electric powered car? Cut pork from the gasoline-engine side of the equation by using a lighter-weight, three- or four-cylinder engine.
According to information leaked by very knowledgeable sources, Fisker is weighing the feasibility of a dedicated range-extended engine after the current crop of Karma models has been launched.
The idea would be to slash anywhere from 110-160 pounds or so from next-gen models’ curb weight by replacing the 255-horsepower, 2.0-liter GM Ecotec engine, which was originally designed for a gas-only car.
The GM four-cylinder “LNF” turbocharged engine weighs about 360 pounds. Fisker is reportedly looking for a 200- to 250-pound turbo to feed the lithium-ion battery in its future cars.
The 1.2-liter Lotus Engineering three-cylinder is one likely candidate. It is produced with Fagor Ederlan Group in Spain, and is said to be the front-runner in consideration for the next iterations.
Fisker’s present generation cars are being built in Finland, according to a Fisker spokesperson. After Q4 of next year, they will be built in a former GM plant in Delaware.
