Mazda Skyactiv-D racer first diesel to run at Indy in 60 years

While it may not be touting the old "Win on Sunday, sell on Monday" axiom we all know and love, Mazda recognizes that racing can only improve its cars. And so it's no surprise that the Japanese automaker is testing and refining its Skyactiv-D diesel engine by sending it out on various race tracks around the country - notably being the first diesel ever to compete at Daytona and the first to notch a Grand Am win at Road Atlanta.
Next up? Indy. It has been over 60 years since a diesel-powered machine ran at the Indianapolis Motor Speedway, and the Cummins-powered racer that competed in the 1952 Indy 500 with a 6.6-liter inline-six-cylinder oil-burner was a fast and brutal machine that set a new lap record in qualifying leading up to the race. Though that car was withdrawn with turbocharger failure 71 laps in, its diesel powerplant left an indelible impression on the racing community, and that's something Mazda hopes to accomplish once again.
Mazda says that the diesel engine in its race car is pretty darn close to stock - 51 percent stock by parts count, and 63 percent stock by weight - which means the way it performs in competition is at least a somewhat meaningful way to the stock engine's durability in the real world. Check out the image of the Mazda6 Skyactiv-D racer posing alongside the 1952 Cummins above (click to enlarge) and feel free to peruse the press release below for the rest of the details.

Mazda RT24-P brings KODO style to the Rolex 24 at Daytona

In addition to its new CX-5 crossover, Mazda revealed its new racecar, the RT24-P, at the Los Angeles Auto Show. The car has been designed for the Daytona Prototype international (DPi) class in IMSA's WeatherTech SportsCar Championship and will make its racing debut at the Rolex 24 at Daytona. It was designed using Mazda's KODO design language, which the brand has so successfully applied to its road-going cars. The racer's relation to Mazda's production cars is made obvious by the small five-point grille at the tip of the RT24-P's nose. While plenty of credit needs to go to the stylists and aerodynamicists at Mazda and Multimatic, one of the companies Mazda partnered with on the car, some of the credit needs to go to IMSA's new DPi rules for 2017. The new DPi class is very similar to the LMP2 class that it competes with in the WeatherTech series, with some noteworthy differences. The DPi class allows manufacturers to create unique bodies and engine packages for one of the four chassis available. The LMP2 class requires competitors to use the chassis companies' bodies, and are restricted to one engine package. View 14 Photos As for the powertrain, the Mazda RT24-P uses a turbocharged 2.0-liter four-cylinder that puts out roughly 600 horsepower. Mazda used the same engine in its P2-class race car last season. Mazda's body and engine will ride atop a chassis developed by Riley Technologies and Multimatic. You may remember that latter company as the one that developed the awesome spool valve shocks on the Chevrolet Colorado ZR2. The RT24-P will be campaigned by Speedsource, a company that has been racing Mazdas in American endurance racing for years, including last year's P2 cars. Considering Mazda's success in making such a cool race car, we're excited to see what other manufacturers do with the extra design freedom of the DPi class. Both Chevrolet and Ford competed last year in the WeatherTech prototype class with Daytona Prototype-style cars, and Honda competed with an LMP-style racer. Depending on what other makes decide, this year's WeatherTech line-up could have some nifty designs.

Mazda3 to showcase CNG, Hybrid versions in Tokyo

Mazda has made huge gains in its competitive set with the introduction of its Skyactiv technologies, and the Japanese automaker appears to have no plans on slowing down. While we're still waiting for the Mazda6 Skyactiv-D diesel to go on sale in the US, Mazda announced that it will debut new Skyactiv-Hybrid and Skyactiv-CNG versions of the Mazda3 (standard US-spec model shown above) at next month's Tokyo Motor Show.
Matching up with what we heard earlier in the summer, the Mazda3 Skyactiv-Hybrid is intended for Japan only, but there are no details about this system regarding fuel economy, electric components or specs. Likewise, there are no details for the Mazda3 Skyactiv-CNG Concept, which is a bi-fuel version of the car running on both gasoline and compressed natural gas. As this car's name suggests, the CNG model is a concept vehicle, and there is no indication that Mazda plans offering such a model here in the US.
In addition to these two vehicles, Mazda will also have an Atenza (Mazda6) on display showing off some vehicle-to-vehicle (V2V) safety systems, called the ASV-5 (Advanced Safety Vehicle). Scroll down for Mazda's official press release.
