SARD Corporation (株式会社サード Kabushiki gaisha Sādo, abbreviated as Sigma Advanced Racing Development) is a Japanese tuning company and racing team from Toyota, Aichi, mainly competing in the Super GT series and specialising in Toyota tuning parts. SARD is also taking part of the 2015 FIA World Endurance Championship season, with a prototype in the LMP2 category, with plans for a future LMP1 entry.
The company was formed in 1972 as Sigma Automotive Co., Ltd by Shin Kato to develop and produce motorsport related parts and accessories as well as operating their own racing team. Sigma began its racing career in the Fuji Grand Champion Series and for the following year participated for the first time in the 24 hours of Le Mans with their Sigma MC73, powered by a Mazda Wankel engine, becoming the first Japanese car to qualify for Le Mans, before retiring early in the race with electrical problems. The team returned for the following year with a Mazda backed MC74, finishing but not making enough laps to be classified. In 1975 the team switched to a Toyota powerplant in the MC75, only to suffer from another early retirement.
Sigma Automotive would continue to compete in numerous domestic series. In 1985, the racing division of Sigma Automotive became an independent company, Kato established a company called Sigma Advanced Racing Development (SARD) specialising in motorsport as well as producing aftermarket parts for Toyota automobiles.
SARD returned to international motorsports in 1989, debuting as a Toyota backed team named Toyota Team SARD in the first round of World Sports Prototype Championship held in Suzuka, using a Toyota 89C-V, also competing in the All Japan Sports Prototype Championship. With the demise of Group C in 1993, SARD switched to the newly formed JGTC series and also return to Le Mans with a V8 powered MR2 known as the MC8-R, having the same spell of misfortune as they had during the 1970s, competing in 1995 and 1996, only to fail to pre-qualify in the face of the newer generations of GT1 cars in the following year. SARD continued to compete in the JGTC with a works Supra. The team now races with a Lexus SC430, with Sato's son Shinji working as a Chief Engineer. In 2006, SARD has also competed at the 24 Hours of Tokachi, a Super Taikyu race, with a hybrid powered Lexus GS450h finishing 4th in class and 17th overall.
For the following year, SARD took their Super GT specification Supra out of retirement, installed a hybrid version of its Super GT 3UZ-FE engine, giving out 480 bhp (358 kW) and 376 lb·ft (510 N·m) of torque. The Supra, rechristened as Denso SARD Supra HV-R and driven by series regulars André Couto, Akira Iida, Katsuyuki Hiranaka and Tatsuya Kataoka started on pole and dominated the race effortlessly throughout to the end which it finished 19 more laps over the runner up, completing 616 laps. It became the first hybrid-powered car to win a race.
In addition, SARD develop and manufacture tuning parts mainly for Toyota cars, namely turbochargers, redesigned fuel systems and cooling systems, suspension parts and aerodynamic kits. The company is not restricted to Toyotas as they are well known within the aftermarket tuning market for their fuelling components used by numerous tuning companies.
