Like with all NASCAR models, the Supra bears only a slight resemblance to the upcoming production car. It's really just a spec race car dressed up in a Supra suit, sharing far more parts with the Ford Mustangs and Chevy Camaros than with any road-going Toyota. All Xfinity Series cars use carbureted 5.8-liter V8s and tube-frame chassis.
The Supra will replace the Camry in the Xfinity Series, though the Camry will carry on in the flagship Monster Energy Series. Since the Camry entered the Xfinity Series in 2007, Toyota has won four manufacturer championships, two driver championships and 147 wins.
The original Supra was a serious competitor in various racing series in the 1980s and '90s, including Super GT in Japan and the IMSA Camel GT series in the U.S. The Supra also raced at the 24 Hours of Le Mans in 1995 and '96. Expect to see the new Supra to compete in similar series in the next couple of years.
