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 Though that car was withdrawn with turbocharger failure 71 laps in, its diesel powerplant left an indelible impression on the racing community, and that's something Mazda hopes to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.

2021 Mazda CX-30 2.5 S gets new name, adds tech, keeps same power

For its second model year, Mazda's in-betweener compact crossover is getting a new-ish name: the 2021 Mazda CX-30 2.5 S. No, those extra digits at the end aren't a trim level. The 2.5 S is apparently part of the name. They also don't indicate a boost in output, as the CX-30 won't be following the example of the recently announced Mazda3 2.5 Turbo. They're all for show. Instead, Mazda adds some new connectivity and safety features to the package. Apple CarPlay and Android Auto are now standard across the lineup. They join Mazda Connected Services with a three-year trial and in-car WiFi hotspot with a six-month or 2GB trial, and they pair with the carryover 8.8-inch center infotainment screen that is controlled by a rotary dial mounted behind the gear shifter. The CX-30 2.5 S keeps as standard the 7-inch reconfigurable digital gauge display, Bluetooth phone and audio, two front USB ports and electronic parking brake. There are also some new safety options to go with the standard i-Activsense package, which includes Mazda’s version of adaptive cruise control with stop and go function, smart braking support, a driver attention alert, lane departure warning with lane-keep assist and high-beam control. Upgrade to the CX-30 2.5 S with Select Package, the second of four trim levels, and you get blind-spot monitoring with rear cross-traffic alert, side mirror turn signals and Mazda Advanced Keyless Entry, plus a leather-wrapped steering wheel and shift knob, leatherette seating and upgraded, 18-inch wheels, among other perks. Step up to the Preferred Package and you get features like a power moonroof, heated front seats and black gloss front grille. The top-tier Premium Package, meanwhile, brings a Bose 12-speaker sound system, a three-month SiriusXM trial subscription, navigation, windshield-projected Active Driving Display, power liftgate, paddle shifters and LED head- and taillights, among other features. As before, power comes from the Skyactiv-G 2.5-liter inline-four that it shares with the Mazda3. It makes 186 horsepower and 186 pound-feet of torque and is mated with a six-speed automatic transmission. The standard setup is front-wheel drive and G-Vectoring Control Plus, but predictive i-Activ all-wheel drive with off-road traction assist is an option across the range for an extra $1,400. Base price creeps up by $55 from 2020 to an even $23,000, including the $1,100 destination fee. Related Video: This content is hosted by a third party.

Mazda returns to rotary with RX-Vision Concept, crowd goes wild

Rotary! Forget everything for a second. Ignore the sleek styling, formed-by-wind sheetmetal, outrageously rear-drive proportions, and general ridiculousness of the sideview mirrors. And please be so kind as to ignore the poorly lit photos here – Mazda has a thing for drama. Concentrate instead on one fantastic phrase from the concept car press release: "next-generation Skyactiv-R rotary engine." The crowd here in Tokyo was downright frothing to get a look at the new concept car – hoping to catch a glimpse of the first evolutionary stage for a RX-9 sports car. The critical factor in that effort is of course the rotary engine. Mazda says that, while production of the powerplant is "on hold," the company has "never stopped research and development towards the rotary engine." The fact that the company has named the new engine gives us great hope that it exists in reality, and will be available for sale at some future date. The devil is in the details though, and there are precious few available at the Mazda stand. Other than a brief history lesson about Mazda's racing heritage, and fuzzy-vision talk about the future, we only have expectations to feed on. Oh, there's also a tiny press release, below. Related Video: HIROSHIMA, Japan—Mazda Motor Corporation unveiled the rotary-powered Mazda RX-VISION sports car concept at the Tokyo Motor Show*1 today. The rotary engine is a symbol of the company's "never-stop-challenging" spirit. RX-VISION represents a vision of the future that Mazda hopes to one day make into reality; a front-engine, rear-wheel drive sports car with exquisite, KODO design-based proportions only Mazda could envision, and powered by the next-generation SKYACTIV-R rotary engine. Rotary engines feature a unique construction, generating power through the rotational motion of a triangular rotor. Overcoming numerous technical difficulties, Mazda succeeded in commercializing the rotary engine, fitting it in the Cosmo Sport (known as Mazda 110S overseas) in 1967. As the only automaker to mass-produce the rotary engine, Mazda continued efforts to improve power output, fuel economy and durability, and in 1991 took overall victory at 24 Hours of Le Mans with a rotary engine-powered race car. Over the years, the rotary engine has come to symbolize Mazda's creativity and tireless endeavor in the face of difficult challenges. While mass production is currently on hold, Mazda has never stopped research and development efforts towards the rotary engine.
