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.

More head-up displays are coming to a dashboard near you

With the exception of Apple products — $1,000 for a freakin' smartphone? — one great thing about tech is you typically get more for your money with each passing year. This is particularly true with automotive tech: Features like driver assists and surround-view cameras that were once exclusively available in luxury vehicles now come standard even on some economy cars. The same thing is slowly happening with head-up displays (HUD). For example, the 10-inch HUD in the 2018 Toyota Camry is one of the largest and best HUDs I've seen in any car. And a big improvement on the much smaller HUD in the latest Toyota Prius. Mazda is another mainstream brand that offers HUDs in several of its vehicles. But instead of embedding expensive components in the dash and using a special windshield, the HUDs in the Mazda3 and Mazda6 use a thin plastic lens that folds down when not in use. MINI has a similar solution, but this low-cost approach has limits in terms of size and position of the images compared to traditional HUDs that use the windshield as a screen. We're also starting to see similar lens-based aftermarket options that can be added to any car. Last year I tested a portable HUD called Navdy that taps into a car's OBD-II port to provide info on speed and RPM and uses built-in GPS and Google Maps to show the surrounding area, display speed limits and route you to your destination. Navdy also connects to an Android or iOS smartphone via Bluetooth to display data from phone calls, texts and music playing on a connected device, and it's simple to use and easily visible in almost any lighting condition. While Navdy is still available online, late last year the company ran into financial difficulties, and product support has been halted. I recently tested a new portable HUD called Hudly that's not quite fully baked and falls short of Navdy because it doesn't tap into an OBD-II port. Since a companion smartphone app for Hudly isn't scheduled to launch until next month, for now it only mirrors what's on a smartphone. So it can be used for nav and other apps, and its features are very limited. Between automakers adding HUDs in more reasonably priced cars and the aftermarket filling in the gaps for existing vehicle owners with add-ons, the technology is becoming more prevalent and affordable. And it's also getting better.

2016 Mazda CX-9 starts at $32,420 with standard turbo engine

The 2016 Mazda CX-9 will start at $32,420 (including $900 for destination) when it arrives at dealers later this spring. The base price is just slightly higher than competitors in the three-row CUV segment like the 2016 Ford Explorer for $31,995 and 2016 Honda Pilot for $31,045. The new model is also more expensive than the 2015 CX-9, which had a $30,865 starting price. All versions of the 2016 CX-9 use Mazda's new 2.5-liter turbocharged engine with 250 horsepower (on 93-octane fuel) and 310 pound-feet of torque, which routes through a six-speed automatic. The combo returns an EPA-estimated 22 miles per gallon city, 28 mpg highway, and 25 mpg combined in front-wheel-drive form. All-wheel drive adds $1,800 to the price of most trims. We found the powertrain to be fantastic during when driving the CX-9 prototype. Even the base CX-9 Sport trim has amenities like LED headlights and taillights, a backup camera, trailer stability assist, and a seven-inch infotainment system. An optional Sport Package for $950 adds a power driver's seat, heated front seats, and heated side mirrors. Customers can really load the CX-9 with tech, though. The Touring model for $36,870 has Blind Spot Monitoring with Rear Cross-Traffic Alert, keyless entry, a power hatch, and an eight-inch infotainment system. The optional Touring Premium Package for $1,745 also adds automatic headlights, LED fog lights, navigation, and Smart City Brake Support. If that's not enough, the Grand Touring for $41,070 features a head-up display, lane-departure warning, lane-keep assist, and radar cruise control. The top spec CX-9 Signature for $44,915 includes all of these features and comes standard with all-wheel drive. It also has Nappa leather upholstery, rosewood trim, LED lighting around the gearshift, and LED accents on the grille.
