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:

2019 Mazda CX-9 Review and Buying Guide | Fun for the whole family

The 2019 Mazda CX-9 crossover is the biggest vehicle in the Japanese automaker's lineup, and the only one to offer a third row of seating. It has only one powertrain option, but offers a wide variety of other content across various trim levels. Many folks are drawn to Mazdas for their elegant design, affordability and driving dynamics that are sharper than most, and the CX-9 has all of that to a certain degree even if it's the biggest, most family-oriented one. Still, the CX-9 may be big for a Mazda, but it's one of the smallest in its segment in terms of third-row space and cargo capacity, so it may not be for every family. What's new with the Mazda CX-9 for 2019? Though largely unchanged from when this generation debuted for the 2016 model year, the Mazda CX-9 gets a few small changes for 2019, the biggest of which is the addition of Apple CarPlay and Android Auto compatibility, which is optional on its lowest Sport trim and standard on the Touring, Grand Touring, and Signature. The transmission has been retuned for a smoother, quieter driving experience. Thicker floor mats and headliner further help to make the car quieter. Each trim gets a little something new, too. Sport now offers an optional Sport Package, costing $1,290, with heated front seats, a power driver's seat, heated mirrors, lane-keep assist, adaptive cruise control and automatic emergency braking. Moving up to the Touring trim, the only other change is a frameless rear-view mirror. The Grand Touring trim gets a new 7-inch info screen in the instrument panel, along with new power-folding side mirrors and a 360-degree camera system. The top-level Signature trim gets new badges, rosewood interior trim, and accent lighting in the grille and around the shifter. Along with the new features, the CX-9 increases in price. The Sport trim costs a mere $150 more, the Touring and Grand Touring trims go up by $370, While the Signature jumps $1,050 compared to the 2018 model. What are the CX-9's interior and in-car technology like? The interior varies by trim level, but with Mazda making moves to grab customers from some of the luxury brands on its "path to premium," the higher grades do look and feel like a high-quality, comfortable place to spend time. It's a spacious interior with room enough for a third row. There are some rally nice materials in use, depending on the trim level, including Nappa leather and something called Santos Rosewood.

Honda, Mazda, Mitsubishi, Mercedes also under diesel emissions scrutiny

The controversy over Volkswagen's diesel emissions scandal isn't limited to the US. In Europe, where diesel engines are far more popular, the issue is shining a harsh light on the NEDC emissions test. As already known, the evaluation does a poor job of reflecting real-world production of NOx, and it appears a significant number of automakers are affected. The Guardian in the UK has been reporting on real-world test results from a company called Emissions Analytics. After the latest round of checks, vehicles from Mercedes-Benz, Honda, Mazda and Mitsubishi were found to generate far more NOx than they should. The newspaper also published similar results for Renault, Nissan, Hyundai, Fiat, Volvo, Jeep, Citroen, VW, and Audi. On average, the figures are about four times over the limit of producing the pollutant. Unlike VW and its defeat device, these automakers aren't actually breaking the rules. The vehicles perform up to the NEDC lab test for emissions, but those results simply aren't translated to the street. "The VW issue in the US was purely the trigger which threw light on a slightly different problem in the EU - widespread legal over-emissions," Nick Molden from Emissions Analytics said to The Guardian. A big fight to decide the future of this issue appears to be on the horizon. Automakers claim that they can't meet the next round of tightening emissions regulations and are asking for compromises. Although, spokespeople for Mercedes and Honda told The Guardian that the brands would be in favor of the stricter rules. Meanwhile, some European governments began backtracking their support of diesels well before this scandal came to light. The added scrutiny certain hasn't helped the future of the oil-burner.
