Engine details (4.0L V8)

The baby brother of the V10, this clean sheet design was introduced for the 2008 season and immediately proved itself as the best LeMans privateer engine, finishing 3rd at the LeMans 24 hours on its debut. The dominance continued in 2009 with pole position and victory at Barcelona, 2nd place at LeMans and victory at Silverstone. The Speedy-Sebah team dominated the Michelin Green X challenge, winning by a huge margin.

In 2010 the Oak Racing team also finished 2nd at LeMans and won the Michelin Green X challenge.

The DB engines are currently used in hillclimb, recently powering Reto Meisel to the Swiss Hillclimb championship, and single seater applications such as the Dallara GP 2 chassis, campaigned by a Boss GP customer.
