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:

Confirmed: Mazda Miata gets more power, higher redline, telescoping wheel

Our friend over at Road & Track, Bozi Tatarevic, has a keen nose for stuff just like today's Miata news, and he spotted an article by the Japanese car magazine Car Watch that details Mazda's upcoming updates. Car Watch actually got to drive the car, too. There's a lot to go through, but the highlight has to be confirmation of what we told you earlier this year about a significant power bump: The Miata will indeed get an increase of 26 horsepower, from 155 to 181. But the power's not the whole story. Mazda has increased the redline from 6,800 RPM to 7,500. It's not clear at this point where torque and power peaks are in the rev range, or how these changes affect low-speed drivability, but more revs are almost always a good thing and aren't likely to detract from the roadster's fundamental goodness. Car Watch reports that lighter pistons and connecting rods are fitted to help reduce rotational mass in the 2.0-liter inline-four. Some valvetrain changes were needed to support the higher redline, mainly stiffer valvesprings to prevent valve float. Mazda also changed the shape of the valves and optimized the intake ports to breathe better at higher RPM. The inner diameter of the exhaust ports were increased to flow better through a new muffler better tuned to the engine's new operating range. This confirms and gives a little more detail to what we reported earlier based on a leaked document from Mazda Canada. Car Watch also confirms that the revised Miata will get a low-inertia dual-mass flywheel, which should help absorb some vibration, noise and harshness from the higher-revving engine without losing too much of the directness that a single-mass flywheel provides. Mazda usually gets stuff like this right, so while we won't know until we get a chance to drive it whether the DMF feels "right," we're not too worried about it. There's also a telescopic steering wheel, a first in any Miata, which has a range of about 1.1 inches. That doesn't sound like much, but it should help folks with longer legs reach the wheel without having to crank the seat forward. Interestingly, Car Watch reports that the telescoping wheel was opposed by some in the company seeking to save every fraction of an ounce of weight, and to get it through, the company apparently had to change some of the material in the upper steering column from steel to aluminum to satisfy the weight-conscious. Little details like these are fantastic.

Mazda to relocate its US offices into Irvine's tallest building

Mazda is the latest foreign automaker to be moving its North American headquarters. Only this time, it's not moving further south. Instead, the Japanese automaker is simply relocating to another facility in Irvine, CA. In a little over a year from now, Mazda North American Operations will move to 200 Spectrum Center Drive (pictured in the rendering at right), taking up five of the 21 floors in Orange County's tallest building for a total of over 100,000 square feet of office space. It'll also take up half the lobby with vehicles on display and the exclusive naming rights on the top of the building. The facility, designed by Pei Cobb Freed & Partners, boasts full glass walls from floor to ten-foot ceiling for uninterrupted 360-degree views. Mazda has been in its current US headquarters at 7755 Irvine Center Drive (pictured above) since 1987. The five-story building was specifically constructed for the purpose and was the tallest in Irvine at the time. Prior to that it was based in Compton from 1970. The move to the new facility is scheduled to take place in February, 2017. Mazda's announcement marks only the most recent of foreign automakers to relocate their North American headquarters. Toyota is moving to Texas, Subaru to Camden, Lotus to Ann Arbor, Daimler to Farmington Hills, and Mercedes-Benz to Atlanta (where Porsche recently relocated, as well). Cadillac also recently moved from GM's Renaissance Center in downtown Detroit to its new headquarters in New York. Hyundai and Kia also quarter their North American operations in Irvine, as does Aston Martin. Meanwhile Honda and Toyota (for the time being) are based less than an hour away in Torrance, and Mitsubishi halfway in between in Cypress. Though they no longer sell passenger cars in North America, Isuzu and Suzuki still operate their US bases in SoCal as well, in Anaheim and Brea, respectively – all municipalities located just south of Los Angeles. Nissan and Subaru also base their US operations outside of California, with head offices in Tennessee and New Jersey, respectively.
