Thus in late 1987, a partnership between Peter Livanos, Victor Gauntlett, Richard Williams and Ray Mallock - through his shareholding in Scottish racing firm Ecurie Ecosse would be formed, creating a new company known as Proteus Technology Ltd. (Protech).

Although not part of the World Sports Prototype Championship in 1989, Aston Martin next turned to the 24 Hours of Le Mans.

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 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.

But Aston Martin were forced to drop out of motor racing due to the economic instability of the company at the time.
