Next-gen Mazda MX-5 Miata mule spied 'Ring testing

Fans of simple, lightweight motoring, rejoice - we now have images of the next-generation Mazda MX-5 Miata undergoing testing at der Nürburgring Nordschleife. Now, to be fair, this isn't some lightly camouflaged example that will give us a great peak of what the next Miata, which will also become the next Alfa Romeo Spider, will look like. This is a mule, with the new bits hidden under a current Miata's body. That doesn't mean there aren't a few scraps of valuable information here, though.
According to our flock of camera-toting spies at the Nürburgring, the next Miata is likely to grow a bit, as new models are wont to do. In particular, it will be longer and wider, and the wheelbase is likely going to be stretched, based on the shape of the wheel wells and doors. Both of those factors will add more space in the cabin.
Those are the big indications provided by these photos, but while the MX-5 might be growing, it's a safe bet based on these images that it, and the (likely pricier) Alfa, will retain the classic, long-hood, short-deck styling that so typifies rear-drive roadsters.

So, just how different are the Fiat 124 Spider and Mazda MX-5 Miata?

"We leveraged a great platform." That's how Bob Broderdorf, Jr., Fiat's North American director, summarizes the creation of the 124 Spider. We all know Fiat's new roadster shares its underpinnings with the fourth-generation Mazda MX-5 Miata, but there are a lot of key differences to keep them separate in the eyes of consumers. Mazda may have engineered the platform, but Fiat added many of its own touches. Here, we'll take a closer look at the spec sheets of the two cars, and summarize the major differences between the Japanese and Italian roadsters. If you need a refresher, read our full First Drive of the 2016 MX-5 Miata, and glance at all the Fiat 124 Spider details in this post. Design Fiat Chrysler design lead Ralph Gilles is super excited about this car. "I think it's going to change lives," he told the assembled media at an event in Auburn Hills, MI, earlier this month. Yes, it's definitely exciting to add a small roadster to any lineup, especially one that uses such a proven platform. But we're not sure people are going to get all that jazzed about it from a design standpoint. You'll either love it or hate it, and we're kind of leaning toward the latter. Every single body panel is new, and the design is "100 percent Italian." There are a number of creases and angles throughout the exterior, with a squared-off rear end and rectangular taillamps. Fiat trusts you'll be able to spot the similarities between the new 124 Spider and the original, but we're not so sure. We can see a bit of the old car's grille on the new car's face, and the dual hood blisters are a nice throwback touch, but that's about it. Trust us when we say that this car looks way better in photos. In person, it really didn't wow us. Of course, beauty is in the eye of the beholder. One colleague told us his wife, a long-time Miata owner, hates the look of the new one but will absolutely adore the Fiat. Good for her, and good for Fiat. But based on design alone, we'll take the Mazda every single time. What about you? Dimensions When Broderdorf said Fiat leveraged the Miata's platform, that means the Italians took it as-is. The two cars ride on an identical, 90.9-inch wheelbase. The front and rear tracks lengths are the same, at 58.9 and 59.1 inches, respectively. But that's where the similarities end.

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.
