Fisker‘s next generation of hot hybrid cars are likely to have lighter, dedicated three- or four-cylinder engines, according to Autoblog. The company is seriously looking into the Lotus Engineering 1.2-liter three-cylinder range-extending engine for the purpose. A dedicated range-extending engine makes sense in the long run, because it significantly lowers the weight of the electric car, allowing it to add more range.
The current 360 pound, 255-horsepower four-cylinder turbocharged GM Ecotec engine, will be replaced by three cylinder engine that weighs about 200 to 250 pounds. The cars will only be released after the current line of Karma variants and Project Nina models have all been launched.
