Sit back and enjoy this 1991 Mazda RX-7 IMSA GTO onboard lap at the Mazda Raceway Laguna Seca. Technically, the full name of the car was the Mazda RX-792P, and was one of just two cars built and raced in 1992 before the project was ended.
The cars combined the rotary 13J engine with a chassis built from carbon fibre by Crawford Composites and bodywork designed by Lee Dykstra. The first two races of the season saw the Mazda Motorsports team of Price Cobb and Pete Halsmer turn up with just one chassis, which unfortunately managed to catch fire before both the Grand Prix of Miami and the 12 Hours of Sebring. Sadly once the car started to run and record top ten finishes, IMSA announced a new open-cockpit prototype category to replace the GTP class, meaning that the RX792P wasn’t able to evolve despite testing showing a 4-rotor engine capable of producing 700+ hp and a reduced weight.
So Mazda North America PR gentleman and amateur racer Jeremy Barnes is one of the few people ever to drive this example of Mazda rotary technology. Despite only producing 640hp, the 9,000 rpm redline isn’t as much af as advantage as the light weight and cornering ability.
