Mazda still has a team working on rotary engines

The flame still burns within Mazda to stage a rotary engine revival. Before you start getting excited, it's way too soon to start saving money for the fabled, next-gen RX-7 or RX-8. Still, company boss Masamichi Kogai confirmed to Autocar that the Japanese automaker has an engineering team dedicated to improving the Wankel. This development group has the hard task of trying to make the rotary stack up to modern internal combustion engines in terms of emissions and fuel-economy standards. Neither factor were ever exactly Wankel's strong suits. Kogai described them as working "very enthusiastically" to Autocar. The boss didn't discuss any future RX-vehicles or the size of the team, however, a report from last year indicated that there were 30 engineers in partnership with universities to update the engine's design. After problems keeping up with emissions and fuel economy, Mazda built it's last rotary for an RX-8 in June 2012. Since then, there have been intermittent rumors of a return. One possible solution was a design called the 16X that was supposed to offer more torque and better fuel economy. Another possibility was a small-displacement unit as a range-extender in an electric Mazda2. Rumors of a new RX-7 have been heard for years. In 2013, Kogai clearly said that it wasn't happening. When asked again last year, he reiterated the same point.

2017 Mazda CX-9 packs turbo power, fresh style

After nearly a decade of sales, Mazda finally introduces the second-generation CX-9 crossover. It delivers a comprehensive interior and exterior overhaul, blessing the CX-9 with a powerful, efficient Skyactiv powertrain, and instilling even more of the sporting character that makes Mazdas so darn charming. Like every other vehicle in Mazda's catalog, the CX-9 now wears the handsome, suave stylings of the company's Kodo design language. We think it looks great, but feel free to disagree in Comments. The second-generation CX-9 is the perfect example of Mazda's growing interior design prowess. As is so often the case, it's not so much the style but the choice of materials that stands out. Nappa leather can be paired with real Japanese rosewood and aluminum accents to craft a cabin that feels far more expensive than what you might expect from Mazda. The quality is impressive, even on the pre-pre-production prototypes we tested (drive impressions coming soon). The other headline, aside from the gorgeous interior, is the powertrain. The heart and soul of the operation is a new 2.5-liter, turbocharged Skyactiv engine. Although it only produces a modest 250 horsepower, that figure is complemented by a whopping 310 pound-feet of torque. Importantly, torque is easy to access in the lower part of the rev range, with peak twist coming in at just 2,000 rpm. It drops off rather suddenly north of 4,000 rpm, but as Mazda tells it, most consumers rarely venture above that figure. Mazda expects the CX-9's core market to be perfectly happy with the robust low-end output. A six-speed automatic is responsible for doling out that grunt, and is meant to play nicely with the same i-Activ predictive all-wheel-drive system found in the CX-5 (although the two cars don't share any AWD components). Using 22 different sensors, the system measures road conditions 200 times every second and will even send up to half the engine's power to the rear axle. The entire car, meanwhile, rides on the same Skyactiv architecture as the CX-5 and Mazda6, meaning a multi-link rear suspension has been paired with MacPherson struts up front. Eighteen-inch wheels will be standard, although 20s will also be on offer. You can expect to hear much more on just what the new CX-9 is like to drive next week. Until then, enjoy the official images from Mazda, and keep an eye open for live shots from the LA debut, headed your way soon.

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.
