Nimrod Racing Automobiles (sometimes referred to as Aston Martin Nimrod) was a partnership founded in 1981 between racing driver and car dealer Robin Hamilton and chairman of Aston Martin Lagonda, Victor Gauntlett. The project was intended to build sports prototypes for the World Endurance Championship and IMSA GT Championship using Aston Martin V8 engines. Although Aston Martin did not own the project, they offered their support for the chance to see success for their name in motorsports without the heavy cost of running their own team.
Nimrod built three NRA/C2s for competition in 1982, with two being run by the works team while the third was sold to Dawnay Racing, a team owned by the then AMOC president Viscount Downe. The cars were capable of running both in the World Endurance Championship's Group C specification and IMSA GT's GTP specification.
Combining a production-based V8 engine from the V8 and V8 Vantage models, the engine was refined by Aston Martin Tickford to handle the increased output. Eric Broadley designed the chassis while his employer Lola Cars International built the tubs. Ray Mallock would later evolve the NRA/C2's design into a B-spec model for the 1983 season.
Debuting at the 1000 km of Silverstone, Nimrod entered one of their own cars alongside the Dawnay Racing privateer entry. Nimrod faced mechanical troubles and did not finish, although Viscount Downe had a sixth-place finish. Problems continued for Nimrod Racing at the 24 Hours of Le Mans where their race was ended early with an accident. Nimrod's only success for the season came at the 1000km Spa, where one of their two cars finished, taking eleventh place. The combined results of Nimrod and Viscount Downe earned Aston Martin third in the constructors championship that year.
