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.

Recharge Wrap-up: Renault-Nissan hits 250,000 EVs, will the next Toyota Prius be an SUV?

Will the next Toyota Prius be an SUV? Mazda and Toyota recently reached an agreement to share powertrain technologies, which will help Mazda comply with California's tightening ZEV restrictions with a plug-in vehicle. On the flip side, Toyota will have access Mazda's Skyactiv diesel powertrain, which a source tells Motoring will be used in an SUV based on the Toyota Prius (and, as Hybrid Cars suggests, on the Toyota C-HR concept). Interestingly, the collaboration will also give Mazda access to Toyota's fuel cell technology, which could mean more hydrogen powered cars on the road and the subsequent expansion of hydrogen fueling infrastructure. Could it also make way for a long-awaited hydrogen powered rotary-engine sports car from Mazda? Read more at Motoring. Samsung SDI unveiled two new lithium-ion stationary batteries at Intersolar Europe. In doing so, Samsung throws its hat in the ring with the likes of automakers Tesla and Mercedes-Benz, using knowledge from electric vehicle batteries in the arena of home solar energy storage. In addition to its 3.6-kWh battery, its new 5.5-kWh and 8.0-kWh batteries offer storage solutions at a larger, more practical scale for solar customers. Called the All-in-One, the battery system, borrowed from electric vehicles, is made up of a photovoltaic inverter, battery PCS and lithium-ion battery, and promises efficiency, compactness, fast installation and an affordable price.

The quarter-millionth EV was a white Renault Zoe sold to a French computer engineer from Bordeaux named Yves Nivelle. While he credits a government program offering a ˆ10,000 rebate for EV buyers trading in an older diesel vehicle for helping him make the decision to pull the trigger on the new Zoe, "I have to say, I was convinced the first time I drove the car. It's a real pleasure to drive and it feels good to do my part for the environment," says Nivelle. The Alliance had sold around 31,600 EVs from January to May this year, up 15 percent from the first five months of 2014. See the video above, and read more in the press release below. Renault-Nissan Alliance sells its 250,000th electric vehicle • Historic EV milestone reached in early June • Alliance sells half of all EVs globally • EV sales up nearly 15 percent through May vs.

Mazda starts production of new MX-5 Miata in Japan

We often regard a new model as having arrived when its manufacturer reveals it for the first time. But you might argue that nothing is official until actual production gets underway. And that's just what's happened now with the new Mazda MX-5. The fourth-generation Miata was unveiled a few months ago, and now the first examples have begun to roll off the assembly line at Mazda's Ujina plant in Hiroshima. The first ones are set to stay in Japan, where the new roadster is being introduced initially. Deliveries are set to launch in June. After that, we can expect the new MX-5 to proliferate to markets around the world, including our own. To date Mazda has sold more than 950,000 of its little roadsters, making it the best-selling two-seat sports car in the world. It shouldn't be long, then, before the new model tips it past the million-unit mark. 2015/03/05 Mazda Starts Production of All-new Mazda MX-5 HIROSHIMA, Japan-Mazda Motor Corporation today began production of the all-new Mazda MX-5 two-seater lightweight sports car (known as Mazda Roadster in Japan) at Ujina Plant No.1 in Hiroshima. The first models produced are destined for the Japanese market. Sales of the all-new MX-5 will begin in Japan around June this year and interested buyers can make an appointment for pre-sale discussions through a dedicated website from noon on Friday, March 20. Following sales start in Japan, the MX-5 will be progressively rolled out to overseas markets. The MX-5 is an iconic model representing Mazda's vehicle engineering philosophy: the pursuit of driving pleasure. With production exceeding 950,000 units as of the end of January 2015, the MX-5 continues to hold the Guinness World Record for the world's best-selling two-seater sports car. In order to respond to ever increasing demands for safety features and environmental performance while maintaining the element of fun that has always defined the model, development of the fourth generation MX-5 was carried out under the motto "innovate in order to preserve". In addition to incorporating SKYACTIV TECHNOLOGY and KODO-Soul of Motion design, development focused on enhancing the senses and sensations through which people enjoy cars. Moving forward, Mazda will continue to enrich the lives of its customers through a variety of touch points including the production of high-quality vehicles, and become a brand that maintains a special bond with its customers.
