The B2K/40 shared some mechanical elements with the larger B2K/10, but was simplified for ease of use. Unlike the B2K/10’s raised footbox and large nose caused by this footbox, the B2K/40 featured a simplified footbox and a flattened nose, though it retained a raised element to help air flow between the cockpit and fenders. The fenders were also simpler, using a narrow wedge shape instead of the B2K/10’s sweeping curves, with radiator intakes placed inside them. A single air intake underneath the rollbar fed the engine, utilizing a cylindrical nacelle instead of a larger scoop that was sometimes used on the B2K/10. Later chassis with turbocharged engines required an additional intake for the turbocharger.
For an engine, the B2K/40 was stipulated by SR2 class rules to use a small, production-based V6. Advanced Engine Research had an agreement with Nissan to modify their production VQ 3.0 Litre V6 for use in the SR2 class, but other engines were also used, including a Mazda turbocharged 2-rotor, a Judd V8, a Porsche Flat-6, and a Ford turbocharged Inline-4 developed by Millington.
The first B2K/40s debuted mid-season in 2000, competing in the Grand American Road Racing Championship, American Le Mans Series, and Sports Racing World Cup. Snow/Schumacher Racing, Archangel Motorsports and TRP Racing ran in the USRRC, while KnightHawk Racing and Phillips Motorsports competed in the ALMS, with Snow/Schumacher Racing making two ALMS appearances. SportsRacing Team Sweden was the only B2K/40 runner in the Sports Racing World Cup. The B2K/40s were successful in the USRRC, earning five class wins – four for Archangel and one for Snow/Schumacher – and securing Archangel the SR2 class championship. In the ALMS, Snow/Schumacher achieved a best result of 11th at Petit Le Mans. At the 24 Hours of Le Mans, Multimatic Motorsports won the LMP675 class, finishing 25th overall and being one of only two finishers in the class.
In 2001, the number of B2K/40s in competition nearly doubled. The USRRC saw the return of Snow/Schumacher, Archangel, and TRP, joined by Northstar Racing, Porschehaus Racing, Multimatic Motorsports, and Rand Racing. The ALMS featured only Roock-KnightHawk Racing in the new LMP675 class, while SportsRacing Team Sweden ran alone in the FIA Sportscar Championship (formerly the Sports Racing World Cup). Archangel again dominated the USRRC, winning six races to claim the championship, with Porschehaus and Rand Racing adding two and one wins respectively. SportsRacing Team Sweden took four class victories and the SR2 championship in Europe. KnightHawk was unable to win in the ALMS, but finished second in the LMP675 championship. They entered the 24 Hours of Le Mans but failed to finish.
2002 saw continued success for the B2K/40. Rand Racing-Risi Competizione was the primary competitor in the USRRC, winning nine races and the championship, with occasional appearances from Porschehaus and Archangel Motorsports. The ALMS saw Archangel Motorsports join Spencer Motorsports, Essex Racing, and Kyser Racing. Archangel took two class victories and finished third in the LMP675 championship. SportsRacing Team Sweden continued in Europe, finishing third in the championship without a win.
Results began to decline in 2003 as the Grand American Road Racing Association shifted focus to their Daytona Prototype class, leaving the SR2 class uncompetitive. Team Essex won the class at the 24 Hours of Daytona, while G&W Motorsports won at Virginia International Raceway, earning the championship due to points earned running a Picchio chassis earlier in the season. Essex Racing was the only ALMS competitor, finishing third in the LMP675 championship without a win. SportsRacing Team Sweden did not return to the FIA Sportscar Championship.
2004 marked the end of the SR2 class in the USRRC and the cancellation of the FIA Sportscar Championship, leaving the American Le Mans Series and the new Le Mans Endurance Series as the B2K/40’s primary areas of competition. Miracle Motorsports, Intersport Racing, Marshall Cooke Race Car Company, and Van der Steur Racing regularly competed in the ALMS, joined by Rand Racing for the 12 Hours of Sebring. B2K/40s won eight races in the LMP2 class, with six for Intersport and three for Miracle, with Miracle Motorsports winning the championship aided by their second car, a Courage C65. Tracsport was the only competitor in the Le Mans Endurance Series, achieving a best finish of third in class and taking third in the championship. Intersport Racing also competed at the 24 Hours of Le Mans, winning their class, again as one of only two LMP2 finishers.
In 2005, regulation changes for the 24 Hours of Le Mans and Le Mans Endurance Series rendered the B2K/40 obsolete, coinciding with the launch of the B05/40 as its replacement. The B2K/40 remained eligible in the American Le Mans Series, where Van der Steur Racing was the consistent competitor, with BAT Competition appearing in select races and Intersport running their car one last time at the 12 Hours of Sebring before upgrading. Van der Steur finished fourth in the LMP2 championship. Van der Steur continued with their B2K/40 into 2006 at select races before upgrading to a Radical SR9.
