50 engineers kept the rotary alive at Mazda for 8 years

The Mazda RX-Vision concept is one of the standouts at this year's Tokyo Motor Show thanks to a drop-dead gorgeous design and a revival of the Wankel engine. The fact that the rotary is still in development at Mazda is thanks to a dedicated group of 50 engineers. According to Automotive News, their dream for the last eight years has been to bring this storied engine design back to the street. It won't be easy. Because of its design, the rotary suffers from poor fuel economy and high emissions. Making the challenge even harder, Mazda reportedly only gives them a small budget, but they continue to chip away at the problem. "These 50 engineers want to develop the rotary engine, therefore they joined Mazda," company research and development boss Kiyoshi Fujiwara told AN. "If I stop the rotary engine, probably they want to leave." For the Skyactiv-R under the RX-Vision's svelte hood, the team reportedly started from the 16X rotary project. Dating back to 2007, that 1.6-liter engine was supposed to improve torque and fuel economy thanks in part to direct injection. After additional development, insiders even suggested that the engineers might have finally solved the powerplant's issues. However, Mazda never put the mill into production, and the RX-8 remains the company's last Wankel-powered model to be offered in showrooms. "We have a dream that one day, this design with a rotary engine will achieve a level that customers will accept," CEO Masamichi Kogai said to AN. Mazda is quite clear that the RX-Vision might never go on sale without a suitable rotary. Although if it does see production, the coupe would likely use a stiffened version of the Miata's chassis, AN reports. Before anyone can place an order, these 50 determined engineers still have a lot of work ahead of them. Related Video:

2016 Mazda CX-5 [w/video]

It's difficult for me to get excited about crossovers. I try hard not to be the stereotypical car guy: ignoring the fact that the rest of the world loves these tall hatchbacks, while yelling, "station wagons make more sense!" until I've voided my lungs of air. Deep down I am that guy, but I work around it. Historically the Mazda CX-5 is one crossover that has been quasi-immune to my knee-jerking. It doesn't weigh two tons, offers a manual transmission (in poverty spec, but still...), and looks faster than its competitors. Most importantly, the CX-5 can round a corner without wobbling like a Slinky at the top of the stairs. No item on that list of plaudits would likely crack the top ten "desirables" for average small CUV shoppers. So, for the 2016 update, Mazda instead upgraded the in-cabin experience along with the requisite nips and tucks to the exterior. I borrowed a 2016 model CX-5 to see whether or not those concessions to comfort affected the car-nerd stuff. And to see if the Mazda could still be my go-to CUV recommendation. Driving Notes The engine options are unchanged for 2016. You can still have the fine, 2.5-liter four-cylinder engine, with its 184 horsepower and 185 pound-feet of torque, or its wimpier 2.0-liter lil' brother. My fully spec'd Grand Touring came with the bigger engine, which feels adequately powerful for the class, but not quick. In an era where turbocharged engines are everywhere, revving the Skyactiv 2.5-liter up to its torque peak at 3,250 rpm takes some commitment. I'm annoyed that there's no manual offered with the 2.5L (a combo I can have in both the Mazda3 and Mazda6), but I don't hate the automatic transmission. The six-speed unit is unobtrusive 99 percent of the time; something I regretfully can't tell you about certain nine-speed autos. There are no paddles to play with, but you can tap the shift lever up and down if you're struck by a need for total control. With a new center console and dash, and the addition of the Mazda Connect infotainment system, the '16 CX-5 feels like a new vehicle from behind the wheel. An attractive, pliant, leatherish material swaths the neat console and surrounding real estate. And the perforated leather seats feel damn near upscale. I think that Mazda Connect's version of the central control knob (with handy adjacent volume knob) is almost luddite-proof in its simplicity. There's no latency between twisting and reaction on the screen.

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.
