Mazda has no plans for an RX-9, despite ongoing rotary development

We know Mazda is capable of making wonderful cars in any form or bodystyle. It also likes to tease enthusiasts with promising concepts like the stunning RX-Vision. In news that's sure to raise the ire of enthusiasts around the world, it seems the automaker has no plans to follow through with a production version of that beautiful, Soul Red coupe. In fact, it doesn't look like Mazda is interested in building any sports car that would slot above the Miata. In an interview with Automotive News, Mazda CEO Masamichi Kogai responded with a simple "No" when asked if Mazda has plans for a larger sports car entry. Kogai was asked if Mazda has any plans for a production rotary. He said that the 1.5- and 2.0-liter engines in the Miata are more exhilarating. That's a debatable and subjective argument that thousands of rotary owners both past and present would likely disagree with. It's more likely that despite ongoing development of the Wankel, Mazda is still struggling to meet emissions standards. Despite the advantages of a rotary (high power-to-weight ratio, compact size, rev-happy nature), it's not very fuel efficient and struggles with emissions testing. Also, despite the prestige and attention a halo sports coupe could potentially bring, Mazda is a small, independent automaker that needs to focus on mass appeal. Creating an all-new design with a unique engine isn't cheap. Badging a non-rotary car as an RX would be sacrilege, so don't expect an RX anything anytime in the near future. Current RX owners should take a moment to lament. Their car probably needs another quart of oil anyway. Related Video:

Mazda G-Vectoring Control makes driving better without you knowing

Mazda has just spent eight years developing a new technology that will make its new cars a lot more fun to drive, even if you have absolutely no idea that it's working. And subtlety's the point, Mazda engineers told us at a press event at Mazda Raceway Laguna Seca. In fact, the effects of what they've dubbed G-Vectoring Control are so fine that the marketing and PR teams are at a loss for how to do their jobs with it. "The engineers have done their work," said Mazda Director of Communications Jeremy Barnes, "But how do we get the message across?" The basic premise is this: G-Vectoring activates only when the car's on-board computer reads simultaneous steering and throttle input. The data — including throttle position, steering angle, and, crucially, how quickly you're adjusting the steering angle — are then funneled through an algorithm to reduce engine torque, which transfers vehicle weight, adding more grip to the wheels that need it. The system will appear first on 2017 Mazda6 sedans arriving in showrooms later this year, followed by the 2017 Mazda3. Actually, "subtle" does not even begin to describe the effect. G-Vectoring Control can detect as much as one tenth of one degree of steering angle, and changes the cornering forces only 0.1 to 0.5 g as a result. "That's less than the human body can feel," explained Vehicle Development Engineer Dave Coleman. In practice, G-Vectoring reduces the steering angle at turn-in, as well as the rate at which one turns the wheel. To demonstrate, Director of R&D Kelvin Hiraishi rode shotgun with us in a specially equipped Mazda6 that allowed him to turn G-Vectoring on or off at the push of a button (production cars will always have it on). Hiraishi had us drive a number of courses, including Mazda Raceway Laguna Seca itself, while an engineer measured our steering inputs with a laptop Matrix'd into the car's electronic brain. I drove the same course several times with the same car in the same conditions, with cruise control locked and the system turned on or off. Lo and behold, with G-Vectoring activated, the engineer's output graph showed that my steering inputs were indeed reduced ever so slightly. There were two times that G-Vectoring was markedly noticeable. The first on a turn with a minor banking toward the outside, and the second was during cornering over an artificially wet section of the course — in other words, when the car was at the limits of adhesion.

Mazda, Suzuki, Yamaha — more vehicle data fabrication found in Japan

TOKYO — Mazda, Suzuki and Yamaha improperly tested vehicles for fuel economy and emissions, the Japanese government said on Thursday, revealing fresh cases of compliance failures by manufacturers. The results came to light after the Japanese government had ordered the automakers to check their operations after revelations of improper testing at Subaru and Nissan last year. The conduct of automakers globally has come under intense scrutiny after Germany's Volkswagen AG admitted in 2015 to installing secret software in hundreds of thousands of U.S. diesel cars to cheat exhaust emissions tests, and that as many as 11 million vehicles could have similar software installed worldwide. In the Japanese cases, the carmakers have not broken any laws or prompted massive recalls. But a growing list of improprieties has tarnished the image of the country's manufacturing industry for high-quality products and efficiency. Suzuki, Mazda and Yamaha cleared vehicles for emissions or fuel efficiency even in cases where they were tested under invalid conditions, the ministry said in a statement. The errors related to slight deviations in the speed of the vehicles during testing that should have invalidated the test results. The automakers examined tests they had conducted over different periods of time, and in Suzuki's case they stretched back to 2012. None of the automakers found significant problems with actual emissions and fuel economy performance of the vehicles, which were destined for sale in Japan, and do not plan any recalls. Suzuki, Japan's fourth-largest automaker, said that of 12,819 sample vehicles tested for fuel economy and emissions since June 2012, around 50 percent of them had been inspected improperly. "I deeply apologize and will lead efforts to prevent recurrence," Suzuki Chief Executive Toshihiro Suzuki told a news conference. Mazda said there were irregularities in 4 percent of similar inspections on its cars, or just over 70 vehicles. In Yamaha's case, irregularities were found in 2 percent of inspections, or just a handful of vehicles. Both Mazda and Yamaha apologized. Suzuki and Yamaha shares fell 6 and 5 percent, respectively, and Mazda shares were down 1 percent, underperforming a steady benchmark Nikkei average. In July this year, Nissan admitted it had improperly measured exhaust emissions and fuel economy for 19 vehicle models sold in Japan.
