    Exactly 50 years ago, in , Mazda commenced development of the rotary engine. After the 24 Hours of Le Mans the B would compete once more at the last race of the season, the km of Autopolis finishing 9th and 10th. It partially improved sales for Mazda's road cars, however. On July 30, , the B No. Today the car is considered by Mazda and Wankel enthusiasts as one of the most iconic race cars to come out of Japan.

    Although the and B lacked the single lap pace of World Championship competitors such as Mercedes-Benz , Jaguar , and Porsche , as well as Japanese Championship competitors Nissan and Toyota , the s had reliability that allowed them to contend for their respective championships. As of , this remains the only victory by a car not using a reciprocating engine design, a record likely to never be repeated due to regulation changes, and the first victory by a Japanese marque.

    Toyota would go on to win the 24 Hours of Le Mans. A total of two s were constructed in , while three newer specification Bs were built in At its heart, the initial design of the was an evolution of the and B designs that had been used by Mazda in and Many mechanical elements of the were carried over by Nigel Stroud when he designed the , [2] but with some notable exceptions.

    Foremost was the replacement of the 's 13J Wankel rotary engine. In its place, the brand new R26B was installed. The custom-built R26B featured a nearly identical layout and displacement , but included new design elements such as continuously variable intakes and three spark plugs per rotor instead of the 20B's two. Porsche 's five-speed gearbox was retained. Other modifications made to the 's design included a relocation of the radiators. Initially placed beside the cockpit on the , a new single radiator was integrated into the nose of the Air moved from the blunt nose of the car underneath the bodywork and through the radiator before exiting in front of the windshield.

    A Gurney flap was located at the radiator exit to increase front-end downforce. This new radiator location also meant a redesign of the doors of the car, where the old radiator design had been located.

    The intake in front of the door and exit behind were no longer necessary and were thus not included, giving the a smoother bodywork design on top. To aid in rear engine and brake cooling, intakes were placed on the side bodywork, immediately above the exhaust cooling vents. As before, Stroud's monocoque design was built from carbon and kevlar by Advanced Composite Technology in the United Kingdom.

    Carbon fiber body panels were affixed to the two initial chassis that were built in Following the season, Mazda continued development of the chassis in order to make improvements on its pace and reliability. One major development was the intake system for the rotary engine. In the past, Mazda had developed variable-length telescopic intake runners to optimize engine power and torque for varying RPM levels.

    For , the system became continuously variable, rather than previous versions that had steps for different engine ranges. The B's onboard ECU controlled the action of the telescopic intake. Three new Bs were built for , while the two existing s were also upgraded with the new intakes. After Fuji, the second chassis was completed, and the team departed for Europe to prepare for Le Mans.

    Former Le Mans-winner Jacky Ickx was hired by Mazdaspeed in order to prepare the two s, as well as an older B, for the race. In qualifying the new s set the 22nd and 23rd fastest lap times, ahead of the B's 34th fastest time.

    The two s ran reliably for much of the race, lasting through the night until problems were encountered in the early hours of Sunday morning. While leading their GTP class, an oil leak on the No. Two hours later, the number two hundred two was also retired after an electrical failure and fire.
