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.

MotorWeek checks out two sides of the '90s Japanese car scene

MotorWeek's Retro Reviews let you feel nostalgic about a huge range of classic cars, and the latest two releases offer a look at two very different sides of the Japanese car market in the 1990s. The video above shows off tuned examples of the Mazda RX-7 and Nissan 300ZX. Check out the clip below to remember the 1997 Honda CR-V, if you want to reminisce about something a little more utilitarian. The RX-7 and 300ZX were among the era's best Japanese sports cars, and these examples' suspension and engine overhauls gave them an extra boost. Peter Farrel Supercars tunes the Mazda, and the vibrant yellow paint and body kit make it look ready for an episode of Initial D. The updated powertrain stands up to the mean styling and gets the RX-7 to 60 miles per hour in 4.5 seconds. The Stillen 300ZX GTZ sports a giant wing, and new turbos take the output to 465 hp. It sprints to 60 in 4.9 seconds. The CR-V sits on the opposite end of the automotive spectrum as the tuned RX-7 and 300ZX, but it's even more important in a historical sense. The Honda (along with the Toyota RAV4 and others) was among the progenitors of today's mega-popular compact crossovers. These early examples set the foundation for offering buyers a utilitarian vehicle in a comfortable package with good fuel economy at an affordable price. The CR-V had some quirky charm, too, like the removable picnic table hidden in the cargo floor. This content is hosted by a third party. To view it, please update your privacy preferences.

Mazda Raceway gets first new MX-5 Cup as pace car

Mazda's motorsports department officially finished the first example of its new MX-5 Cup racer. But while the rest of the fleet will be used in the Global MX-5 Cup championship, this initial unit has been designated for another purpose. It's been dedicated to serve as the new pace car for Mazda Raceway Laguna Seca. Based on the latest ND-generation MX-5, the Cup racer was previewed in racing spec this past November ahead of its debut at the SEMA show. Though we've still yet to see the final spec sheet, it clearly benefits from key upgrades to the rolling stock, not to mention the added roll cage, racing buckets, and more. The pace car also features emergency lighting and a livery designed by Mazda and applied by Sticky Fingers Design out of Huntington Beach, CA. The beefed-up little roadster will join a cadre of pace cars used at the legendary Northern California circuit. Other pace cars in the fleet include a Mazda6, RX-8, CX-5, and the previous Miata. The season is winding to a close at Laguna Seca, with the Pirelli World Challenge finale and Mazda Road to Indy still set to take to the track next month.

(August 13, 2015) – Mazda Motorsports used the annual car-fest known as the Rolex Monterey Motorsports Reunion to roll out the first production 2016 Mazda MX-5 Cup race car. This particular vehicle is guaranteed to lead races as it will be the newest pace car in the Mazda Raceway Laguna Seca fleet of Mazda safety vehicles. The 2016 Mazda MX-5 Cup race car follows a 26-year history of the MX-5 Miata in motorsports. The first race cars to be sold to customers will be used in the 2016 Global MX-5 Cup, known in the U.S. as the Battery Tender Mazda MX-5 Cup. With the 2016 racing season still many months away, placing the first production race car into pace car duty allows Mazda to gather additional durability data while showcasing it in front of one of the most influential motorsports crowds of the year. "For Mazda, this weekend is the perfect blend of past, present, and future," noted John Doonan, director of motorsports for Mazda North American Operations. "We are celebrating our motorsports heritage on the track with our vintage race cars.
