Fast Facts – Formula Mazda

Formula Mazda was founded back in 1984 with the first race taking place at the 1984 Long Beach Grand Prix as a support event.
The cars have a welded steel tube frame chassis, fiberglass body panels, a 180 hp carbureted Mazda 13B rotary engine, and a 5-speed Hewland Mk 9 transaxle.
The engines are sealed and most modifications to the cars are banned, in order to keep the playing field as level as possible and to ensure that driver skill is showcased.
Many drivers who competed in Formula Mazda went on to compete in the highest levels of open-wheeled American racing, including both Scott Speed and Michael McDowell.

Formula Mazda

Formula Mazda began almost by accident. Mazda had agreed to develop five cars for the Jim Russell Racing Drivers School in California, these cars would all be identical open-wheeled racers powered by Mazda’s famous rotary engine.

Above Video: This footage from 2019 shows the car from this article being cold started, it shows you the procedure for turning it on and you can hear the unusual rotary engine note.

25 additional cars were then developed and build by Marc Bahner of Bahner Engineering, and it would be these cars that formed the grid for the first Formula Mazda race, which was held as a support event for the 1984 Long Beach Grand Prix.

These cars were built to be identical, with a welded steel tube frame chassis, lightweight fiberglass body panels, in-board front shock absorbers with double A-arms, and rear suspension consisting of twin trailing links, an upper link, and a lower A-arm.

Power was provided by a mildly-tuned Mazda 13B Wankel rotary engine producing 180 bhp, these engines were then sealed before the season began to ensure a level playing field. Power was sent back to the rear wheels via a 5-speed Hewland transaxle.

Formula Mazda quickly became known for its close racing, helped along by the fact that the cars were almost identical. It became an excellent showcase for up and coming driver talent, and a springboard up to the higher open-wheel formulas for many drivers.

In 2004 a new Formula Mazda car was introduced, it was a ground-up redesign that used the more advanced 13B-MSP Renesis Mazda rotary engine capable of 250 bhp. These cars were about three seconds a lap faster than their forbears, however both were permitted to race alongside one another.

This is the tuned 180 bhp Mazda 13B Wankel rotary engine that powers the car, it’s a four-plug engine fitted with a Weber Tipo 8D carburetor.

In 2020 Formula Mazda was cancelled by the SCCA governing body and Formula X was introduced. Formula X was developed to open the field up to many kinds of open-wheeled racing cars of a similar speed, including Formula 4, Formula Mazda, and F2000 cars.
