The Mazda RT24-P race car was unveiled at the Los Angeles Auto Show in November 2016, ushering a new era in the prominent history of Mazda Motorsports’ flagship endeavors in North America. The new car competes under Daytona Prototype international (DPi) rules in the Prototype class, the top level of the IMSA WeatherTech SportsCar Championship. It made its racing debut at the 2017 Rolex 24 at Daytona in late January. In 2018, Mazda Team Joest will make its debut as a team at the 2018 edition of the 24-hour endurance classic in Florida and the team will continue to use the Mazda RT24-P.
Mazda is known globally for the engineering and design excellence of its vehicles, and the new Prototype is no exception. The bodywork of the race car was developed by Mazda designers utilizing the KODO – Soul of Motion design philosophy. KODO represents the instant that energy becomes motion, such as the muscular beauty as an animal pounces or a human leaps into action. The KODO design cues on the Mazda RT24-P include the sleek body contours and the five-point Mazda grille.
“KODO design is at the heart of any vehicle that carries a Mazda badge, and that is very evident in the design of the 2017 Prototype,” said Ken Saward, senior manager of Design at Mazda Design Americas, which falls under the Mazda North American Operations umbrella. “We considered the two main parameters of designing a successful race car for this series: aerodynamic performance and the new-for-2017 technical regulations. Working with Multimatic’s aerodynamicist and engineers, we discovered that applying the KODO design philosophy to the surfaces and the silhouette of the car enabled us to create a dynamic, purposeful-looking design and a very aerodynamically efficient one.”
The Mazda RT24-P uses the Riley Mk. 30 chassis, developed by Riley Technologies in relationship with Multimatic. Riley Technologies is a prominent chassis design and development company with 99 race wins and nine Prototype season championships in North American endurance racing since 2004. Canadian-based Multimatic has worked with Mazda since 2014 in the Prototype category, and has developed and built some of the world’s premier on-road supercars and successful sports cars for the race track.
The Mazda RT24-P is powered by the Mazda MZ-2.0T engine. The approximately 600-horsepower engine, developed and raced with Advanced Engine Research (AER), is a 2.0-liter, inline four-cylinder turbocharged engine.
“This is a huge moment for Mazda Motorsports and the entire Mazda family,” said John Doonan, director of Mazda Motorsports North America. “To have a car which features Mazda design language at the top level of our motorsports program is meaningful for us as a brand.”
“Mazda has good, long-standing relationships with Riley and Multimatic, and was happy to have been the first to test their new chassis.”
What’s in a Name?
The Mazda RT24-P name echoes the Mazda Road to 24, a driver development program that provides scholarships to help championship-winning drivers progress from grassroots into the upper categories of professional sports car racing. The “24” also represents the two-liter, four-cylinder race engine. The “P” signifies Prototype.
