Aston Martin DB9 4WD Plug-in Hybrid revealed by Bosch (video)

Bosch has built a plug-in hybrid Aston Martin DB9 We’ve always believed one of the best uses for hybrid powertrains is to provide extra performance on high-end cars, something Bosh has demonstrated by fitting the Aston Martin DB9 with a hybrid setup. The hybrid DB9 hasn’t been built to preview a production hybrid DB9 (although it probably should) but to demonstrate what Bosch can do with an existing car.
