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.

Mazda and Isuzu to collaborate on a new pickup truck

After decades, Mazda has finally untangled itself from its relationship with Ford. The last vestige of that partnership is the BT-50, a rebadged version of the global Ford Ranger pickup truck. Once the BT-50 ends production, Mazda has announced that it will collaborate with Isuzu to develop its next generation of pickup trucks. The BT-50 was co-developed with Ford's Australian division. In their current iteration, the BT-50 and its Ranger twin were never on sale in the United States. Mazda's last pickup in the US was the B-Series, itself also a rebadged version of the old Ford Ranger. Isuzu pulled out of the US passenger vehicle market in 2009, although it still sells commercial vehicles here. Isuzu, continuing a long and complicated relationship with General Motors, co-developed the diesel engine that currently powers the Chevrolet Colorado and GMC Canyon. In select markets, Isuzu sells a rebadged version of the Colorado as the D-Max. Details on the Mazda/Isuzu tie-up are scarce. A single press release simply says "Isuzu will produce next-generation pickup trucks for Mazda, based on Isuzu's pick-up truck model." This isn't the first truck collaboration between the two companies. Since 2004, Mazda has sold the Titan, a rebadged version of the Isuzu Elf commercial truck. The Elf is sold in the US as the Isuzu N-Series. Those in the US hoping for a new competitor in the midsize-truck segment shouldn't get their hopes up for the new truck. There are currently no plans to bring them here. There is hope, though, that Ford will bring the Ranger replacement stateside sometime in the next few years.

Next Mazdaspeed3 could go naturally aspirated?

The new Mazda3 is a stunner, both aesthetically and from a driving perspective. As with all good things, though, there's always room for improvement. That's where the wizards from Mazdaspeed come in. Mazda's in-house tuner has been tweaking and turbocharging the five-door Mazda3 since 2007, with impressive results.
We've shown you renderings of what the third-generation Mazdaspeed3 could look like, and for the most part your response was quite positive. Now, AutoExpress has come out with details of just what might be under that long hood. According to our friends across the pond, the new Mazda3 MPS (that's what the Speed3 is called in Her Majesty's auto industry) will be arriving with a new, high-revving, naturally aspirated engine. Wait, what?
Yes, if the rumors are to be believed, the next Mazdaspeed3 will ditch its turbocharger. According to an anonymous engineer, the new MS3 will arrive in December (this is for the UK market, mind you) with a 200-horsepower, naturally aspirated engine. The 2.0-liter mill is based on the Skyactiv engine in the new 3, and should be capable of a sub-seven-second run to 62 miles per hour.
