It was either
Zeewolf or
Roadkill in 1994.
Roadkill was ok, but it was no Supercars 2, and the track layouts were just not interesting enough after a while.
Zeewolf was really impressive and a lot of fun, but there was quite a difficulty spike later on in the game that I didn't get over. The Amiga was in regular use until 1997, but no new games...
