The BTC-T Proton Impian is a BTC-Touring class racing car that was built for the 2002 British Touring Car Championship season by Team PSP, who ran Proton's official works program.

[2] Based in Norfolk, the team were forced to purchase the cars from local dealerships, due to the difficulties of importing bodyshells from Malaysia.

[4] Both drivers were retained for 2003,[5] but the fully revamped car [6] proved uncompetitive, and it finished no higher than a 5th place in the hands of Leslie, gained in the first race of the season at Mondello Park, gained mostly due to the attrition of the Touring-class cars.

[7] Leslie slipped to 11th in the championship, whilst Bennett once more finished in 16th, as Proton remained 4th in the Manufacturer's standings.

2004 would prove even less successful - Watson-Smith achieved a fine 14th in his debut season, but Hairuman could do no better than 23rd in the championship, with Proton once again finishing 4th, and last, in the Manufacturer's championship - on 325 points[11] behind the 3rd-placed Seat Sport UK, who were competing in their first season with the Super 2000-spec Seat Toledo.
