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.

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.

Most reliable cars and trucks of 2022

Related: Least reliable cars and trucks of 2022   For years now, Consumer Reports has been one of the most prolific sources of vehicle reliability data around. The organization tests a number of vehicles each year and surveys its members on various automotive topics, including reliability. The results of its 2022 annual auto survey are in, and the list of most reliable vehicles has been revealed. Unsurprisingly, Toyota and Lexus dominated the list of most reliable vehicles, but BMW and Mini snuck into the top 10 as well. The list includes: Toyota Corolla Hybrid: 93 Lexus GX: 91 Mini Cooper: 89 Toyota Prius: 89 Mazda MX-5 Miata: 85 Lincoln Corsair: 82 Toyota Corolla: 81 Subaru Crosstrek: 80 BMW 3 Series: 80 Toyota Prius Prime: 77 In terms of the most reliable vehicle type, Consumer Reports says that sedans remain the best choice. Their average score is 58, which is notably better than SUVs’ average score of 51. Minivans and pickup trucks are lower, at 44 and 39, respectively. As Consumer Reports notes, many sedans are older models that have allowed their manufacturers to iron out the wrinkles, making them more reliable. Domestic automakers' SUVs and trucks performed better in the survey than their imported counterparts, with scores of 45 and 41, respectively. The study also showed that hybrids and plug-in hybrids are becoming more reliable, and have climbed the score ladder to the tops of their segments in many cases.  Consumer Reports says its study includes 17 trouble areas, including small stuff like creaks and rattles and much larger problems like drivetrain failures. The organization states that it weights each issue based on its severity to create its predicted reliability scores, with 100 being the best. A car must be in production for at least two model years to be considered for the list.

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.
