The new Mazda RT24-P race car was unveiled yesterday at the Los Angeles Auto Show, ushering in a new era in the prominent history of Mazda Motorsports in North America. The new car will compete under Daytona Prototype international (DPi) rules in the Prototype class, the top level of the IMSA WeatherTech SportsCar Championship. After significant on-track testing, it will make its racing debut at the 2017 Rolex 24 at Daytona in late January.
The new DPi’s bodywork has been developed by Mazda engineerings using 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. “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.”
Managing the two-car Mazda Prototype factory race team meanwhile, is Florida-based SpeedSource Race Engineering. The Prototype is built using the new 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 will be powered by the Mazda MZ-2.0T engine which raced during the 2016 IMSA season. 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. We believe we have the right team, the right drivers and the right chassis to win races and championships.
“Mazda has good, long-standing relationships with Riley and Multimatic, and is happy to be the first to test their new chassis. We look forward to seeing it make its racing debut at Daytona with Mazda bodywork and the Mazda MZ-2.0T engine. The strategic vision of IMSA to give auto manufacturers this opportunity to integrate our branding to better engage our passionate fans is unique and we’re proud to be the first to unveil what is possible.”
The Mazda RT24-P name echoes the Mazda Road to 24, a driver development program that provides scholarships to help 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.
