Two 757s entered the 1986 24 Hours of Le Mans, but both failed to finish the race due to gearbox problems, marking the first time Mazdaspeed had failed to finish at Le Mans. In the All Japan Sports Prototype Championship season, Mazda was able to come home 3rd in the manufacturer's championship. For 1987, two 757s were again entered, with one finishing 7th overall while the other suffered engine failure. Along with a good result at the joint World Sportscar Championship and All Japan Sports Prototype Championship event at Fuji, Mazdaspeed was able to achieve 10th in the teams championship for WSC and 3rd in the manufacturer's championship for JSPC. A lone 757 was brought out again for 1988 alongside two newer 767s and was able to beat both 767s to place 15th overall.
