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.

2014 Mazda3 2.0L Hatchback officially rated at 40 mpg highway

The Environmental Protection Agency has spoken, and these are the miles per gallon numbers it has officially bestowed on the 2014 five-door Mazda3 hatchback with the SkyActiv-G 2.0-liter engine: 29 city, 40 highway, 33 combined when fitted with the six-speed manual; 30 city, 40 highway and 33 combined when equipped with the six-speed automatic.
Those numbers exactly match the fuel economy targets that Mazda had set for the car when optioned with the 2.0-liter Skyactiv-G with 155 horsepower and 150 pound-feet of torque. For comparison to other cars in the segment, the EPA numbers for the 2013 Honda Civic sedan are 28 city, 39 highway, 32 combined when its 140-hp, 1.8-liter four-cylinder is paired with the five-speed automatic. The Hyundai Elantra GT gets 27 city, 37 highway and 30 combined according to the EPA when its 148-hp, 1.8-liter four-cylinder is paired with either a six-speed manual or six-speed automatic transmission. The numbers for the 2014 Ford Focus aren't out yet.

Mazda shows lightweight MX-5 Spyder and Speedster at SEMA

Ever since Mazda dropped the first teaser on us last week, we've been looking forward to seeing what it had in store for us at SEMA this year. Now we've seen it what Mazda has dubbed the MX-5 Spyder and MX-5 Speedster, and they were worth the wait. The Spyder goes vintage with a silver paintjob and a brown top stretched overhead. It also has an aero kit, grille, and tonneau cover done up in carbon fiber, rides on 17-inch wheels, and features a natural leather interior. The blue Speedster, meanwhile, goes for the stripped-down, wind-in-your-hair experience. It has no roof or windshield, just a tiny deflector at the front of the dashboard. It's dropped an inch closer to the ground on an adjustable coilover suspension with 16-inch alloys, and features a center-exit exhaust. Carbon fiber helps trim 250 pounds from the curb weight, along with a stripped out interior trimmed in Alcantara. Both look pretty slick, and disappoint only in so far as they (like so many of their predecessor concepts) won't be heading for production. If they were, we'd be hard pressed to choose between the two. Which would you go for? Mazda Reveals Extreme Lightweight Design Concepts at 2015 SEMA MX-5 Concepts Display Two Different Takes on Staying True to Pure, Lightweight Sports Car Philosophy LAS VEGAS (November 3, 2015) – Mazda revealed two design concepts today at the SEMA Show in Las Vegas, based on its all-new 2016 MX-5 Miata—MX-5 Spyder and MX-5 Speedster—demonstrating two vastly different takes on lightweight, open-air performance. Lightweight. Fun-to-drive. Roadster. Those three tenets have served as the foundation for the Mazda MX-5 Miata since its 1989 introduction and continue to serve the new fourth-generation model. Focused, lightweight engineering is a guiding principle of every Mazda vehicle made with SKYACTIV Technology, allowing for greater efficiency, improved performance and agile handling dynamics. But what if that sense of lightweight performance were taken to the extreme? What if Mazda's North American designers harkened back to vintage roadsters to create thoroughly modern, bespoke concepts for what a lightweight performance car should be The results would be the MX-5 Spyder and MX-5 Speedster concepts. "Both MX-5 Spyder and MX-5 Speedster are uncompromising designs that highlight the core strengths of MX-5," said Ken Saward, design manager, Mazda North American Operations.
