PAPENBURG, Germany, Oct. 21, 2004 -- Earlier this month, Mazda set a host of international speed and distance records as a group of journalists drove two Mazda RX-8s for 24 hours at full throttle at the automotive proving grounds in Papenburg, Germany.
In all, the Mazda set a total of 40 Fédération Internationale de l'Automobile (FIA) records with two Mazda RX-8s in the categories A (Special Vehicles) and B (Mass Production Vehicles).
The RX-8s were piloted by 15 automotive journalists from 11 countries. All were licensed by the FIA to participate in the event. Other than occasional pauses for necessary pit stops and to change drivers, it was full throttle around the track.
Before the endurance record attempt began, the German Motor Sports Organisation DMSB e.V. had selected three production Mazda RX-8s in Antwerp, Belgium and sealed their engines and transmissions. All remaining stages of the record attempt were accompanied by commissioners of the DMSB e.V. to make sure that all FIA rules and regulations were followed.
The only difference between the two Mazda RX-8s that took part in the endurance trials and RX-8 production models was added safety equipment -- both had special body-contour seats, five-point seat belts and a roll cage.
The record setting began on Saturday, October 2 when Mazda Motor Europe engineer Shoji Tokuda waved the green flag and started the 24-hour drive. The driver accelerated, shifted through the gears and held the line at full throttle.
During the record attempt, journalists drive the two Mazda RX-8s at consistently high speeds without incident, even though everything did not go according to plan. An hour after midnight, it began to rain. To make the cars less prone to hydroplane, JĂĽrgen Herschel from the tire supplier Kumho lowered the tire pressure.
On Sunday, October 3, Shoji Tokuda dropped the checkered flag and waved the two Mazda RX-8s into the pit. When it was over, Mazda set a total of 40 international FIA records. Mazda RX-8’s RENESIS engine, the world’s only production rotary engine, had been driven for 24 hours without a mechanical problem. With average speeds of 133 mph (212.835 km/hr) and 134.9 mph (215,934 km/h), the two RX-8s drove more than 3,106 miles (5,000 km).
Record-setting performances of this kind are nothing new to Mazda, which boasts a long tradition of 24-hour endurance races. In this latest 24-hour attempt, both Mazda RX-8s shattered a Mazda record set in 1991 by Bertrand Gachot, Johnny Herbert and Volker Weidler at the 24 Hours of Le Mans, one of the most prestigious automobile races in the world. That year, the team drove a Mazda 787B race car with a 690 horsepower rotary engine 3059 miles (4,923 km) during the 24 hours of the race, with an average speed of 128 mph (205.133 km/h).
"The RX-8 and the RENESIS engine are the ultimate and most advanced examples of a rotary-powered production car in history," said Tokuda. "Our effort at Papenburg, with the cooperation of Fédération Internationale de l'Automobile (FIA), was a chance for Mazda to once and for all to establish its rightful ownership of these awards."
