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.

2019 Mazda3 pricing starts at over $20,000, 2.5-liter engine standard

Pricing for the 2019 Mazda3 hatchback and sedan has been announced, and the base price has gone up by about $3,000. The new cheapest model is a front-drive, automatic Mazda3 sedan, and it starts at $21,895. The base Mazda3 now has the 186-horsepower 2.5-liter 4-cylinder as the standard engine, whereas the old model came with a 155-horsepower 2.0-liter engine and manual transmission as standard. Compared like-to-like, a 2018 Mazda3 in a similar spec would be slightly more expensive ($22,035) than the 2019 model. Opting for the hatchback on the base trim adds an additional level of equipment, with 18-inch wheels instead of 16-inch ones, Apple CarPlay and Android Auto, dual automatic climate control, leather wrapped steering wheel and shift knob. It also gets more safety equipment including blind-spot monitoring, automatic emergency braking, radar cruise control, automatic high-beams, automatic wipers and lane-departure warning with lane-keep assist. That all adds up to a $2,600 price increase over a base sedan. These features are available on the sedan for an extra $1,600 in the form of the Select package. For all other trims, opting for the hatchback adds $1,000. Higher trim levels add features such as better sound systems, real leather, a sunroof, heads-up display and power heated seats. In addition to pricing, Mazda revealed drivetrain options for the Mazda3, and they're not great for fans of manual transmissions. The Mazda3 hatchback with front-wheel drive and Premium trim is the only manual offering, and it starts at $28,395. On the upside, at least Mazda isn't relegating manual transmissions to the stripped out versions, but on the downside, there isn't a cheap manual option for those on a budget. And of course, if you want the sedan or all-wheel drive, the six-speed automatic is your only choice. Mazda has told us that it could match a manual with all-wheel drive, but clearly it doesn't see a market for that in the U.S. But like with the addition of the turbocharged Mazda6 and CX-5, if there's demand, such a combination could become available, but keep in mind the odds will still be slim. You can see the full breakdown of trims and prices below. The 2019 Mazda3 will be available in March.

A Mazda Miata with a Hellcat V8 exists, and it can be yours

Mazda Miatas with V8 swaps aren't unusual. Kits are available to drop in LS V8s from GM, and some even let you drop in an old Ford 5.0-liter V8. But a Miata with a Hellcat V8 is something special, and this one can be yours. As Automobile spotted, it will go across the block at the Barrett-Jackson Las Vegas auction. This particular 1999 Miata has a build history you can check out for yourself, too. It was all chronicled on YouTube channel KARR. Obviously the Hellcat engine does fit between the wheels, but the hood had to be cut open for the intake manifold and supercharger to fit. The front bumper and lights have been changed to the 2001+ NB Miata design. According to the listing, it has suspension components from V8 Roadsters, a company that specializes in Miatas with twice the normal number of cylinders. In the middle of the car is a manual transmission, which connects to a Ford 8.8-inch differential that's been welded up. With that much power and an essentially locked rear diff, it should make for an excellent drift car. Fortunately it also has 10-inch wide wheels for more grip, and upgraded Wilwood brakes to stop it. It will go for auction at Barrett-Jackson's Las Vegas event, which runs Oct. 3-5. There is no estimated price for the car, which is understandable since nothing like it has crossed the block before. It will go to a new owner, whatever the price, as it is being listed as "no reserve." So if you want to win burnout contests or get loads of stares at next year's Woodward Dream Cruise, you could do a lot worse than picking up this tiny monster.
