Fiat 124 spied with top down

With fall officially here, the days are rapidly running out for much of the country to put the top down and enjoy a convertible. Fiat apparently wants to take advantage of the good weather while it lasts, given these fresh spy shots of the 124 Spider testing with the roof down. In terms of styling, these photos show the droptop with an extremely similar look to the ones from July. The roadster still appears to have rounded headlights and a wide grille up front, which the kidney-shaped cladding does nothing to hide. The hood bulge continues to be there, too, and so is the spiderweb-pattern camouflage. However, these new shots let us check out the roll hoops that are visible with the top out of the way, and we even get to see the manual roof in operation. Also, note there are now dual exhausts at the rear, rather than the quad tips from before. Underneath all this camo and cladding, we know that the 124 Spider shares underpinnings with the new Mazda MX-5 Miata. The engine remains a mystery, but competing rumors suggest the 1.4-liter turbocharged four-cylinder from the current 500 Abarth or the 1.7-liter turbo four from the Alfa Romeo 4C. Thankfully, an answer might not be too far away because the roadster is mooted to debut this year, possibly at the Los Angeles Auto Show in November. With the latest Miata receiving high praise from critics, the motoring world soon gets to find out whether Fiat can find any room for improvement. Related Video:

2016 Mazda MX-5 Miata a knight in white satin

We're not going to lie to you. The reason you're seeing the fourth-generation Mazda MX-5 Miata on these pages again is solely because this is the first time we're seeing the roadster displayed in a color other than the ruby shade it was first shown in. Okay, okay, so this is the first time the Miata is being displayed at a North American auto show other than SEMA, and we'd say that this is the first time Mazda is showing a US-spec model, but clearly this is a right-hand-drive car. Either way, there's still not much to it yet, especially since Mazda is still withholding power and performance figures.
As expected, the ND Miata, as it is already known among the cognoscenti, will receive a 2.0-liter Skyactiv four-cylinder and the buyer's choice of a six-speed manual or a six-speed automatic here in the US. The 1.5-liter model engine that had been linked to the car back in the rumormill stage will not make it to our showrooms.
Preliminary specifications still show the Miata measuring just 154.1 inches in length overall, with an increased track width to 68.1 inches and a low, low overall height of 49.0 inches. Despite the larger-displacement engine and its presumably heavier weight, Mazda is still claiming ideal 50:50 weight distribution and a weight loss of over 220 pounds versus today's NC generation. All of which sounds like the Miata has the right ingredients to make good on its promised Jinba Ittai ("rider and horse as one") driving experience.

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.
