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 Subaru Forester vs compact SUV rivals: How they compare on paper

We've seen what the 2019 Subaru Forester looks like (pretty much the same). We've found out how much it's going to cost (just a bit more). And also how much bigger and more powerful it'll be (appreciably on both counts). Now it's time to see how all of that compares to its top compact SUV rivals. While you can see the same engine and dimension specs for every compact SUV here, for this comparison featuring the latest 2019 Forester info, we've decided to define "top rivals" as those that the 2018 model was most frequently cross-shopped with. That means the 2018 Honda CR-V, 2018 Toyota RAV4, 2018 Mazda CX-5 and 2018 Nissan Rogue. At the time of this writing, none of their respective manufacturers had released data for 2019 models. We also included info for the 2018 Forester as well. So, without further blather, cue the Spreadsheet-o-Matic 3000. How big are they? The 2019 Forester may look nearly identical to the compact crossover it replaces, but it's nevertheless bigger and heavier. In particular, its wheelbase has increased from being the smallest in the segment to one that's pretty much average. It's a good bet that this gain is the reason rear seat legroom has also increased. Width is also up, but the Forester actually remains the narrowest compact SUV. As for other noteworthy dimensions, the new Forester now has the most maximum cargo capacity of any compact SUV with 76.1 cubic feet. Now, it should be noted, that's without the panoramic sunroof that comes on all but the base model. With it, max capacity shrinks to 70.9 cu-ft. Two points about that. First, Subaru is the only company that calls out this difference, and all the others almost certainly are not measuring with a sunroof. Second, this gives you an idea about how much of "maximum cargo capacity" includes space up high where you're probably not storing much cargo. As such, we included the Forester's biggest number and think it fairly indicates Subaru should carry the "biggest in segment" crown. How do their engines and fuel economy compare? Here's the most important takeaway here: The new Forester is tied for the best fuel economy in the segment, but that's with standard all-wheel drive. Everything else listed above is with front-wheel drive. The 2019 model also gets a welcome injection of power, resulting in the fourth-most base horsepower in the segment (or fifth, if you consider the CR-V technically holds spots 1 and 3).

2016 Mazda CX-5 recalled to address failing DRLs

Mazda announced Tuesday that it will recall more than 35,000 examples of the 2016 CX-5 crossover to address an issue that may lead to deterioration or failure of its LED daytime running lights.  In affected models, the gasket used to seal the wiring harness to the LED module was not manufactured to Mazda's specification. As it degrades over time, it can release sulfur, which in turn can potentially corrode the LED control circuit, causing the LEDs themselves to flicker, illuminate poorly or even fail outright.  Per Mazda, there is no alert for this condition, so drivers can potentially lose daytime running light function without realizing it, leaving them tougher to spot in poor light.  The campaign will cover 36,761 CX-5s sold in the U.S. and U.S. territories. Mazda says no accidents or injuries related to the issue have so far been reported.  This new campaign has not yet been published in the National Highway Transportation Safety Administration (NHTSA) recall database, and Mazda's statement did not include details of the proper remedy for the issue or when customers can expect to be contacted to arrange for service.  We expect that all 2016 CX-5s with LED DRLs will receive new harness gaskets and that those showing signs of LED module corrosion will have those replaced as well.  The 2016 CX-5 has been the subject of four other recall campaigns — including one for an improperly torqued steering knuckle bolt and another for a defective fuel filler pipe — but this is the first  new campaign for that model year since 2016.  Related Video: This content is hosted by a third party.
