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 RT24-P brings KODO style to the Rolex 24 at Daytona

In addition to its new CX-5 crossover, Mazda revealed its new racecar, the RT24-P, at the Los Angeles Auto Show. The car has been designed for the Daytona Prototype international (DPi) class in IMSA's WeatherTech SportsCar Championship and will make its racing debut at the Rolex 24 at Daytona. It was designed using Mazda's KODO design language, which the brand has so successfully applied to its road-going cars. The racer's relation to Mazda's production cars is made obvious by the small five-point grille at the tip of the RT24-P's nose. While plenty of credit needs to go to the stylists and aerodynamicists at Mazda and Multimatic, one of the companies Mazda partnered with on the car, some of the credit needs to go to IMSA's new DPi rules for 2017. The new DPi class is very similar to the LMP2 class that it competes with in the WeatherTech series, with some noteworthy differences. The DPi class allows manufacturers to create unique bodies and engine packages for one of the four chassis available. The LMP2 class requires competitors to use the chassis companies' bodies, and are restricted to one engine package. View 14 Photos As for the powertrain, the Mazda RT24-P uses a turbocharged 2.0-liter four-cylinder that puts out roughly 600 horsepower. Mazda used the same engine in its P2-class race car last season. Mazda's body and engine will ride atop a chassis developed by Riley Technologies and Multimatic. You may remember that latter company as the one that developed the awesome spool valve shocks on the Chevrolet Colorado ZR2. The RT24-P will be campaigned by Speedsource, a company that has been racing Mazdas in American endurance racing for years, including last year's P2 cars. Considering Mazda's success in making such a cool race car, we're excited to see what other manufacturers do with the extra design freedom of the DPi class. Both Chevrolet and Ford competed last year in the WeatherTech prototype class with Daytona Prototype-style cars, and Honda competed with an LMP-style racer. Depending on what other makes decide, this year's WeatherTech line-up could have some nifty designs.

Honda sees sales up but profit sliding 16 percent in 2017-18

TOKYO - Honda forecasts a 16 percent fall in operating profit for the current financial year as the Japanese automaker sees higher auto sales being offset by a stronger yen and research-and-development costs. Japan's No. 3 automaker said it expects an operating profit of 705 billion yen ($6.34 billion) in the current FY2018, down from 840.7 billion yen posted in the fiscal year just ended, and lower than an average estimate of 850.8 billion yen from 23 analysts polled by Thomson Reuters I/B/E/S. It sees a 14 percent slide in net profit to 530.0 billion yen this year, down from 616.5. Honda's projections are based on a forecast that the yen will average 105 yen to the U.S. dollar through next March, stronger than the 108 yen rate in the year just ended.BUT CAR SALES ARE UP At the same time, there's good news as Honda expects its global vehicle sales to edge up 1 percent to 5.08 million this year, bolstered by growth in Asian sales to 2.06 million units, beating out North America to become Honda's top market as more Chinese drivers flock to its cars. The company expects to sell 1.92 million vehicles in North America, 2.5 percent less than the year just ended as it struggles to sell sedans including the Accord, which have fallen out of fashion in the past few years. Honda has been ramping up production of SUVs to keep up with strong demand for larger models in the United States, although overall vehicle sales show signs of slowing following a boom cycle after the global financial crisis. Mazda is taking a similar strategy, announcing on Friday it would expand production of SUV crossover models at home, while equipping overseas plants to enable more flexible production of models according to market needs. Japan's No. 5 automaker forecast a 19 percent jump in operating profit for the current financial year as it expects higher sales volumes, particularly in North America, to help it recover from last year's profit slump.A CONSERVATIVE OUTLOOK Executive Vice President Seiji Kuraishi acknowledged that Honda's expected currency hit of 95 billion yen was based on a "conservative" yen forecast, adding that growing costs to create next-generation cars would also impact earnings. "Our costs are rising to develop new technologies which will be needed in the future, like automated driving functions and electric cars," he told reporters at a results briefing.
