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's first-quarter profit slumps on weak sales in U.S. and China

TOKYO — Mazda reported a 79% drop in quarterly operating profit, falling significantly short of estimates, as it continues to struggle with declining U.S. and Chinese sales, while a strengthening yen also cut into its bottom line. Operating profit at JapanÂ’s No.5 automaker was 7.0 billion yen ($64 million) in the first quarter ended June, versus around 33 billion yen a year ago and less than half of an average forecast for 18.5 billion yen from analysts polled by Refinitiv. Mazda, however, reiterated its forecast for a 33% rise in operating profit to 110 billion yen in the year ending March. ThursdayÂ’s profit announcement marks MazdaÂ’s poorest first-quarter operating performance since the June 2012 quarter. The automaker has been struggling with falling demand for its cars over the past year or so, while it is also recovering from flood-related damage to its factories in Japan that led to a quarterly loss in the July quarter of 2018. The Nikkei business daily on Wednesday had reported that operating profit at the company would fall around 70% for the quarter due to lower sales in the United States. Mazda posted global sales of 353,000 units for the quarter, down 12% from a year ago. Its sales in the United States, its biggest market, fell 15% to 68,000 units, while in China, Mazda sold 54,000 vehicles, down 21% on the year. A trade war between the top two economies and slowing growth in China, the worldÂ’s biggest auto market, have prompted a broad-based sales downturn in the global auto sector. Automakers are grappling with easing demand for cars just as they must invest heavily in new technologies including electric cars, autonomous driving technologies and ride-sharing services to survive a major industry shift away from car ownership. Many of MazdaÂ’s rivals at home and abroad have been reporting disappointing quarterly results, with Nissan and Ford also announcing job cuts and possible plant closures earlier this month. The United States is a key source of revenue for Mazda, but it imports all its vehicles sold there, exposing it to a threatened hike in U.S. tariffs on imported cars from Japan. To limit its vulnerability to possible tariffs and currency fluctuations, Mazda is investing in a new plant in the U.S. state of Alabama, a joint project with Toyota.

Mazda RX-9 could be a 400-hp, 2,900-pound coupe due in 2019

Mazda poured fuel on the white-hot rumors of an RX-8 successor with the RX-Vision earlier this year. The long, low rotary-powered coupe was lovely, but as we reported, it wasn't going to happen. But now, there's another chapter in the RX rumormill, and like overnight parts, it's from Japan. Japanese site Holiday Auto claims that Mazda will debut the so-called RX-9 at the 2019 Tokyo Motor Show. But before that happens, the Zoom-Zoom company will preview the production model with a concept at next year's Tokyo Motor Show. 2017 is important, marking 50 years since Felix Wankel had the screwy idea for his eponymous engine and 40 years after the company's first rotary powered car, the Cosmo, hit the market. Exciting as Holiday Auto's report is, the stats on this long-rumored car are better – via Google Translate, the Japanese site claims the RX-9 will use a 1.6-liter, two-rotor Wankel with a single turbocharger. It's good for around 400 horsepower. Holiday Auto isn't exaggerating when it claims the car could have "bike-like acceleration." As with other Mazda products, a low curb weight is key, which is why engineers are targeting a meager 1,300 kilograms (2,866 pounds) for the production model – that weight should be pretty evenly split, too, thanks to a rear transaxle. So yes, the RX-9 will be stupid fast and extremely agile. But it will come at a cost. And by cost, we mean that the RX-9 will start just south of eight million yen. That's $79,641 at today's rates, or enough to purchase about 2.5 RX-8 R3s, the hardcore handling trim of Mazda's last-gen rotary car. And if Mazda follows Nissan's GT-R pricing model, we'll see a six-figure RX-9 by 2025. When it comes to Mazda rotary rumors, grains of salt are a must. That's doubly true when we're talking about a possible concept that won't debut for over a year. But with the RX-Vision, Mazda showed that it hasn't abandoned rotary power, and with 2017 marking a big anniversary for the technology, it seems unlikely that the company will let the date pass without some acknowledgement. A concept car seems like a solid bet. Related Video:
