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.

Honda’s electric SUV is coming soon. Here’s what we know about the 2024 Prologue
2024 Honda Prologue Front

Slowly, but surely, every large car company is getting on board with electric cars. While most of them have released at least one electric model so far, some are still readying their first.

Did you know, however, that Honda is not one of those latter companies? The Honda Clarity was taken off the market a few years ago, and finally, it now looks like Honda is preparing to launch its first of a new generation of electric cars -- the 2024 Honda Prologue SUV.

Chrysler Halcyon concept is a return to glory for the minivan brand
Profile view of the Chrysler Halcyon concept with its doors open.

Chrysler plans to launch its first EV in 2025, but the foundational brand of automotive conglomerate Stellantis may be taking a detour on the road toward that goal. In 2022, Chrysler showed the Airflow, a concept car reportedly previewing that first production EV. But now the brand has a new EV concept dubbed the Halcyon.

Where the Airflow was a handsome but sensible crossover SUV, the Halcyon is a bit more fanciful. The low-slung four-door looks like Chrysler's attempt to clone the Porsche Taycan. It's even got front-fender air outlets like the Porsche, part of an aerodynamic package that includes a sliding rear diffuser and a rear spoiler. It's all meant to minimize aerodynamic drag and improve range. An air suspension system can also adjust to further enhance efficiency, or improve driving dynamics, according to Chrysler.
