Mazda’s RT24-P race car pulls 600hp from a tiny four-cylinder engine

Mazda used the 2016 Los Angeles Auto Show to unveil its 2017 CX-5 SUV, but it also brought something a little more exciting.

The Japanese automaker debuted its latest race car for the IMSA WeatherTech SportsCar Championship, which will race under the new Daytona Prototype international (DPi) rules for that series. It’s called the RT24-P, and will make its racing debut at the 2017 Rolex 24 at Daytona 24-hour race in January.

Racing is a valuable marketing tool for automakers, which is why the Mazda has such an ungainly name. The “RT24” represents the Mazda Road to 24, a driver development program that provides a path for aspiring racers to enter the professional ranks. It’s something Mazda likes to promote to show its commitment to motor sports, which in turn backs up the “Zoom-Zoom” marketing of its road cars.

The “P” stands for “Prototype,” meaning the car is purpose built for racing rather than based off a production model. Mazda says the “24” also signifies the engine, which is a 2.0-liter turbocharged four-cylinder. Mounted behind the driver, that tiny engine produces an astonishing 600 horsepower.

Small engines have been Mazda’s calling card since it started racing in the Prototype class back in 2014. Its cars were initially powered by a 2.2-liter diesel four-cylinder, which was supposed to tie in with plans to offer the same engine in a U.S.-market production model. Those plans were eventually put on the back burner, and Mazda switched to the current 2.0-liter gasoline engine for the 2016 season.

While the engine carries over, the body is completely different. The new car is based on a Riley Mk. 30 design, but Mazda tried to incorporate some of its own “Kodo” design language. That’s especially apparent up front, where a grille similar to ones on Mazda’s road cars creates a distinctive look, although it probably serves no real function. Even if doesn’t take the checkered flag, Mazda is clearly aiming to win the race-car beauty contest at Daytona in January.

Only a short month and half ago, Tesla CEO Elon Musk told investors that outside of the just-released driverless robotaxi, a regular Tesla model priced at $25,000 would be “pointless” and “silly”.

"It would be completely at odds with what we believe,” Musk said.

It looks like the end of the road for Cruise robotaxis
A Cruise autonomous car.

Autonomous-driving operations at Cruise look certain to end after its main backer, General Motors (GM), said it will stop funding the initiative.

GM, which has owned about 90% of Cruise since 2016, announced the decision in a statement shared on Tuesday. It follows a challenging period for Cruise after one of its autonomous cars ran over a woman after she was knocked into its path by a human-driven car in San Francisco in October 2023. The incident led to California regulators suspending Cruise's license to test its driverless cars on the state's streets, a decision that prompted Cruise to pause operations in other locations where it operated. It restarted low-level testing in Arizona in May 2024.

The long-awaited Hyundai Ioniq 9 is finally on its way. Hyundai has taken the wraps off a production-ready version of the electric SUV, showing a modern vehicle that could well be the electric SUV to beat when it finally rolls out to the public. But it will have to contend with Hyundai’s sister company in order to truly gain the title of best electric SUV in its price range. The Kia EV9 has been a go-to option for a few years now.

But is one of these SUVs actually better, or are they just different? We put the Hyundai Ioniq 9 and the Kia EV9 head to head to find out.
Design
There are some similarities in the designs of the Hyundai Ioniq 9 and the Kia EV9, but they also look a little different. First, the similarities. Both vehicles are clearly SUVs, with larger blocky shapes. But, while the Kia EV9 has straight lines and sharper angles, the Ioniq 9 is a little curvier, with a rounded roofline and sculpted curves in the side panels.
