Modern turbodiesel powertrains already match gasoline-electric hybrids in fuel-economy and often outmatches them when it comes to driveability and performance, but a combination of the two separate technologies could provide a perfect blend of performance and economy.

The idea of a diesel-electric hybrid is nothing new. Several automakers, such as France’s PSA Peugeot-Citroen and Mercedes-Benz, have revealed plans for diesel-electric hybrids, and now General Motors has joined the fray.

The American auto giant is reportedly working on developing a range of diesel-electric hybrid powertrains that could be in production within the next five years.
