Aston Martin will enter its factory LMP1 team in this year's Le Mans 24 Hours and next month's Sebring 12 Hours.
The British constructor had been expected to sit out the 2010 season while developing a new car for 2011, but will now take two LMP1 cars to Le Mans and one car to the American Le Mans Series opener at Sebring, the next round at Long Beach and the LMS season opener at Paul Ricard in April.
AUTOSPORT reported last week that Mexican driver Adrian Fernandez was working on a deal to race an Aston in the ALMS, and the former Champ Car racer and reigning ALMS LMP2 champion will join the team's lineup for the program.
Stefan Mucke, Darren Turner, Harold Primat and Chris Buncombe have all been retained, and Aston Martin Racing is due to announce a sixth driver in the next few weeks. The team is also set to enter selected races this season after Le Mans, but the details are still to be confirmed.
"We are looking forward to a great season of racing and we hope to have another strong showing at Le Mans," said team boss George Howard-Chappell. "I'd like to welcome Adrian to the team, I'm sure with his experience he will be a great addition to our driver lineup."
Aston Martin will also have an increased GT program in 2010, supporting two teams in the GT1 World Championship and one in the FIA GT2 series. Works drivers Mucke, Turner and Tomas Enge are racing in the new GT1 series.
