DENSO’s close relationship with World Endurance Championship racing goes back to Group C in the 1980s. In 1983, DENSO’s Research and Development Department 10 creating a racing business in order to supply parts for Group C cars and constructed a full-fledged support system. We'd add something about the TS040 being one of the most advanced racing machined ever created, competing in the LMP1 class which is known to be one of the pinnacles of innovation in motorsport. Since then, DENSO has given broad support to racing activities through parts and sponsorship. DENSO also participated in the 24 Hours Le Mans race in 1987 with the DENSO Toyota 87C under contract with Toyota Team TOM’S, as well as at Le Mans in 1993 by providing full sponsorship for three DENSO Toyota TS-010 cars, and in 1994 with the DENSO Toyota 94C-V under contract for Toyota Team SARD, achieving a rank of second overall.
