Patent application suggests Mazda rotary return

A recent patent application by Mazda reveals that the Japanese automaker is still working on the rotary engine. This could in fact be the Skyactiv-R engine found in the RX-Vision concept from the 2015 Tokyo Motor Show. As with anything Wankel-related, nothing is certain until Mazda makes a production commitment. But this filing suggests that serious development is happening in Hiroshima. The 2011 Mazda RX-8 was the last rotary-powered car you could buy in America. Slow sales, poor fuel economy, and tighter emissions standards prevented Mazda from committing to a follow-up. But the fundamental principles of the rotary - compact size and light weight - perfectly fit Mazda's Skyactiv ethos. (For an explanation of how rotaries work, click here.) In this new engine the intake port sits at the bottom of the engine with the exhaust port on top instead of the other way around. That allows for lower mounting, which improves a car's center of gravity. This rotary is also turbocharged. Putting the turbo up high helps ensure it doesn't get in the way of any body or chassis crossmembers. The implication of those claims is that somebody is thinking about how to put this engine in a car. There are other benefits as well. The short path from the exhaust port to the turbo ensures minimal turbo lag. It also allows for a close-mounted catalyst on top of the enigne, which will help emissions. Another innovation in this new engine is a triangle-shaped rotor that covers part of the exhaust port. This allows for different exhaust flow characteristics. The filing claims that that two of the four orientations allow for less airflow resistance in the exhaust port. As in previous Mazda rotaries, there are two spark plugs to manage ignition timing and combustion. But unlike in the 16X concept, Mazda's last public display of such an engine, the new rotary uses port fuel injection. Keep in mind this is only a patent application. A Mazda spokesperson refused to comment on future product, but commented "As we stated at the Tokyo motor show, Mazda is doing all that it can to bring a rotary to the market." In the meantime, keep your RX-7 prayer candles lit and hope for the return of the rotary before the end of the decade. You can bide your time by reading the entire application here.

2021 Mazda CX-30 Review | Even more power to impress

The 2021 Mazda CX-30 is one of those cars that can be considered an alternative to a variety of segments. It provides a higher seating position than compact hatchbacks like the Mazda3, with which it's nearly identical under the skin. It's smaller than bigger, pricier compact SUVs like Mazda's CX-5 or the Honda CR-V, yet it's also more spacious and refined than subcompact models like the Hyundai Kona. Meanwhile, its ritzy interior, sleek styling and budget-Porsche driving dynamics mean you can legitimately cross-shop it with luxury models like the Audi Q3, BMW X2 and Mercedes GLA. Actually, not only can you cross-shop it with those, we think it's a much smarter purchase. The CX-30 was one of the most compelling new cars introduced last year, and it gets even better for 2021 thanks to the introduction of the new 2.5 Turbo model. It's still not vice free, though: The tech interface isn't ideal for Apple CarPlay and Android Auto, and we aren't alone in thinking that the huge plastic wheel arches look cheap rather than evoking some sort of Subaru-like off-road cred. Yet taken as a whole, this in-betweener alternative should make sense for a lot of buyers, no matter which type of car or SUV they initially started looking for. What's new for 2021? Apple CarPlay and Android Auto are now standard even on the base trim level, while reverse automatic emergency braking and stop-and-go-capable adaptive control are now available. However, the big news is the new CX-30 2.5 Turbo model that produces 227 horsepower and 310 pound-feet of torque on regular gas – a robust amount that blows away its nearest competitors and further justifies its near-luxury aspirations. The base engine is now indicated with the name CX-30 2.5 S. What's the CX-30 interior and in-car technology like? Like the Mazda3 with which it shares so much, the CX-30's cabin makes you go "wow" considering its price and the vehicles with which it competes. Whatever trim level you're considering, the key to this wow factor is how Mazda's new dash design scheme removes visual clutter by reducing switchgear and effectively hiding air vents and door handles. It's then augmented by standard two- or three-tone color schemes – cars with cloth or leatherette vinyl upholstery are accented with black and blue dash/door trim, while those with leather get black and brown. For a car in the $20,000-$30,000 range, it looks and feels special. It's also of a high quality and quite functional.

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.
