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 Though that car was withdrawn with turbocharger failure 71 laps in, its diesel powerplant left an indelible impression on the racing community, and that's something Mazda hopes to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

2018 Mazda CX-5 Buying Guide | Specs, safety, expert reviews, and more

Crossovers are all the rage these days, and spunky Mazda devotes half of its six-vehicle portfolio to the segment. The compact CX-5 slots right in the middle of its crossover lineup, size-wise, and outsells all other Mazda vehicles by a country mile, with sales continuing to climb so far in 2018. The CX-5 was the first car to feature Mazda's KODO design language, which has given its vehicles a more premium appearance and made the CX-5 longer-looking and more taut. Now in its second generation, Mazda offers the CX-5 in Sport, Touring and Grand Touring trims, with the option of front- or all-wheel drive configurations. This Autoblog buyer's guide is aimed at helping you to make an educated decision about whether to buy the 2018 Mazda CX-5. We'll summarize safety and reliability ratings, engine specs and horsepower, fuel economy ratings and pricing. We'll also touch on what Autoblog's professional reviewer thinks of the crossover. Is the 2018 Mazda CX-5 safe? Based on its crash tests, the National Highway Traffic Safety Administration gives the 2018 CX-5 a four-star overall rating. It awards five stars for frontal- and side-crash protection, and four of five stars for rollover crashes. The Insurance Institute for Highway Safety further vouches for the 2018 Mazda CX-5, giving the crossover its coveted Top Safety Pick + award — at the time of this writing, the only compact crossover to get this rating, thanks to available adaptive headlights. It also has good ratings for all of its crash-test metrics and headlights, a superior rating for front-crash avoidance, with optional equipment, and an acceptable rating for the ease of use of the child-seat LATCH anchors. We encourage you to visit the NHTSA and IIHS websites to review ratings on the specific vehicle you're researching. Is the 2018 Mazda CX-5 reliable? J.D.

2018 Mazda CX-5 spied testing in Southern California

It appears the replacement for the Mazda CX-5 is on its way. The current model, though a few years old at this point, is still one of our favorite crossovers on the market. Its combination of handsome styling, practicality, and a genuine fun-to-drive nature make it a winner in our hearts. Hopefully this new model doesn't stray too far from that winning recipe. At least on the outside, that seems to be the case. The spy photos reveal Mazda's Kodo design language in full bloom. The general shape is the same as the current model, but the curves are a little tighter and appear similar to the new CX-9 and Chinese-only CX-4. The grille loses the horizontal bars for a deep-set mesh pattern, while the whole fascia appears to be more upright. The headlights and taillights look to be slimmer and slightly re-sculpted versions of the current shape. Other details for the upcoming CX-5 are scarce. The crossover is expected to debut next year as a 2018 model. It's unknown what engines or transmissions will be available, though the current powertrains are likely to carry over. There's also the rumor of a Mazda diesel making its way over, but, as always, it seems like a long shot. Related Video:
