2003 began to see a decline in results for the B2K/40. The Grand American Road Racing Association was beginning a shift towards their Daytona Prototype class, and rule restrictions left the SR2 class uncompetitive. This meant a handful of teams participated in only a select number of races. Team Essex would win class at the 24 Hours of Daytona while G&W Motorsports would win at Virginia International Raceway, earning them the championship due to points earned running a Picchio chassis in the class earlier that season. Essex Racing would be the only competitor in the American Le Mans Series, finishing third in the LMP675 championship yet not earning a single win. SportsRacing Team Sweden's B2K/40 would also not return to the FIA Sportscar Championship.
