Geoff Crammonds Stunt Car Racer was released in 1989 and was a stunning game. Taking place on an elevated track (imagine Hard Drivin crossed with a rollercoaster) and you drove in a dragster type car against two other drivers. There were four divisions with increasingly difficult race tracks in each division. The car you drove had crash damage and to speed things up a turbo that could be used for a short period in each race. Stunt Car Racer was the best game on the Spectrum IMHO.
