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. Aston Martin donated the DB9 to Bosch for the hybrid project, and Bosh has fitted the DB9 with three electric motors – one at each front wheel and one next to the Aston’s V12 – which gives the DB9 something in the region of an extra 250bhp to play with.
