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 Though that car was withdrawn with turbocharger failure 71 laps in, its diesel powerplant left an indelible impression on the racing community, and that's something Mazda hopes to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

2019 Mazda CX-5 fuel economy takes a hit with new turbocharged engine

We learned all about the 2019 Mazda CX-5 last week, and now we've discovered fuel economy for its new 2.5-liter turbocharged engine. Unsurprisingly, it gets slightly worse fuel economy than its naturally aspirated counterpart. The 2019 turbo crossover, which only comes in all-wheel drive form, gets 22 mpg city and 27 mpg on the highway. Front-wheel drive CX-5s with the naturally aspirated 2.5 liter net you 25 mpg city and 31 mpg highway — all-wheel drive drops 1 mpg in both categories. For a little comparison, the turbocharged engine makes 250 horsepower and 310 pound-feet of torque on 93 octane gasoline, while the non-boosted engine makes 187 horsepower and 186 pound-feet of torque. You're definitely taking a hit in fuel economy, but the gain in power might be worth it, since the decrease isn't that terrible. Cars in its price and power range with all-wheel drive have comparable fuel economy. The Ford Escape with the 2.0-liter turbo is rated at 20/27; Chevrolet's Equinox with the 2.0-liter turbo is 22/28 and the VW Tiguan gets 21/29. There isn't really a clear winner in fuel economy for this much power when you look around the segment, but Mazda's engine is half a liter larger than everyone else. This translates to better torque than most of its competitors, but Mazda manages similar fuel economy. Also similar to many of these decked-out compact crossovers is the new high price of the Mazda we wrote about before. You won't be getting in to the turbocharged CX-5 for any less than $35,865. If you wanted a bigger Mazda like the CX-9, its fuel economy figures aren't significantly worse than the CX-5. Front-wheel drive versions are rated 22/28, and it drops 2 mpg in each category for all-wheel drive. The updated 2019 CX-5 should be coming to dealers soon.

Mazda teases CX-4 for the Beijing Motor Show

Mazda will unveil the CX-4 crossover at the Beijing Motor Show in late April, and the company's single teaser image (above) suggests the CUV might borrow styling cues from the larger Koeru concept. Mazda kept details about the CX-4 light for now but says in the announcement, "this is a new type of crossover SUV designed to help customers live more creative lives." The teaser photo offers some hints about the design. For example, the rear pillar comes to a point and features chrome accents, which are elements from the Koeru and production CX-9. The arching roof rail suggests a coupe-like shape because it arcs downward to the hatchback. The name also hints that this model slots between the CX-3 and CX-5 in the lineup, but the CX-4 appears to prioritize style over utility. We can't wait to get a better look because this picture doesn't offer much detail. The company will also show versions of the Mazda3 and Mazda6 for the China Touring Car Championship at the Beijing show.
