The car is most famous for taking two LMGT1 class wins at Le Mans 24 Hours (2007 and 2008) by the Aston Martin Racing factory team.

For the 2007 24 Hours of Le Mans, Prodrive made modifications to the DBR9 design to not only improve performance, but also to increase driver comfort in the cockpit.

Due to new regulations put into place by Le Mans organizers, the DBR9 required the installation of an air conditioning unit, to prevent overstressing drivers.

Aston Martin capped their 2006 ALMS season by finishing second in the GT1 Manufacturer's Championship, earning the factory team an automatic entry to the 2007 24 Hours of Le Mans.

The DBR9 came into the 2006 FIA GT Championship being title contender favourites, but the season was somewhat lacklustre with only two victories at Mugello and Dubai.

BMS Scuderia Italia cited a problem with finding the right tyre compound with their Pirellis as the factor for their lack of success.

To celebrate that historic victory, Aston Martin built a very limited edition of the DB9 called the DB9 LM (Le Mans), which featured a unique colour, called the Sarthe Silver (named to the track where the Le Mans racing is held), also DBS clear taillights, specific wheels, Magnum silver meshes and crossbar, Sport Pack as standard, a specific interior with red stitching and tertre rouge facia trim.

Later in 2007, Aston Martin launched another limited production, the DBS road car which has many styling cues taken from the DBR9 in conjunction with the James Bond film Casino Royale.

Unlike the DB9 LM, which was an ultra-exclusive (only 60 built) cosmetic package, the DBS brought many technology from the racing world.

In 2008, while Larbre and Scuderia Italia moved on from Aston Martin, Prodrive continued to field a two-car factory team at the 24 Hours of Le Mans.

The #009 numbered car, with the new Gulf Oil sponsored paint scheme, driven by Darren Turner, Antonio Garcia and David Brabham, won its class.

A Le Mans-spec DBR9 participated in the 2009 Super GT season, marking Aston Martin's debut in the series.

It was meant to race at the 2009 24 Hours of Le Mans but Gigawave ditched the DBR9 to focus on the Nissan GT-R GT1 programme.

The car was used in Gigawave's first Le Man Series race of 2009, the final round at Silverstone, where it won the GT1 class.
