to continue on, was able to finish in 11th place overall. Due to a lack of time between Le Mans and the 3rd round of the World Sports Prototype Championship, Aston Martin decided to skip it, returning instead at Brands Hatch where AMR1/04 took home an exciting 4th-place finish in front of the British crowd, then following it up with an 8th-place finish at the Nürburgring. For the 6th round of the year, the World Sports Prototype Championship again returned to British soil. Aston Martin therefore decided to run two AMR1s at Donington Park, debuting newly built chassis #05. The two cars were able to finish 6th and 7th. Both cars raced again at Circuit de Spa-Francorchamps where Aston Martin suffered their only other failure to finish in the season, chassis #04 having suffered engine failure. However, chassis #05, which had now been upgraded with an even more powerful 720 hp, Version II 6.3 L V8, was able to finish a respectable 7th. For the final round in Mexico, Aston Martin decided to take only chassis #05, where they finished 8th. Ending the season, Aston Martin had finished 6th in the Teams Championship, behind the factory Mercedes-Benz, Porsche, Jaguar, and Nissan teams, although they were able to defeat the Toyota team. Cancellation AMR2 At the time of the end of the 1989 season, Protech was already beginning development of the AMR2 for 1990. With the intention for this car to race alongside another two AMR1's in the 1990 24 Hours of Le Mans. The AMR2 combined the chassis of the AMR1, a newer and more powerful 6.3L Version III V8, and an evolved, more aerodynamic body design. The AMR2 was promised to be faster in a straight line than the AMR1 (with a predicted top speed of 230+ mph), a problem which had greatly hindered AMR1 at Le Mans. However, with the announcement from the FIA that Group C engine regulations were to change to only allow 3.5 litre normally aspirated engines from 1991, There was not the budget available to develop a new engine and Protech was disbanded and closed in February 1990 before the chassis AMR2/06 could be completed. AMR2/06 was later built up from left over parts and fitted with an AMR1 body. Aesthetically AMR2/06 looks exactly the same as an AMR1 even with the same Mobil 1 livery.
