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.

Weekly Recap: Tesla loses money, still dominates the news

Some people get an inordinate amount of attention. In politics, it's Donald Trump. In football, it's Jim Harbaugh. And in the auto world, it's Elon Musk and his always-fascinating electric car company, Tesla Motors. General Motors is spending $877 million to upgrade a factory. So what! US auto sales are up. Who cares? Tesla has a metal snake that will recharge your car! So was the week in Tesla – er, the industry. Snarkiness aside, Tesla did dominate the news cycle, led by the announcement the company lost $184 million in the second quarter. Tesla also said it expects to deliver between 50,000 and 55,000 vehicles this year, and is preparing for a full launch of the Model X crossover in September. Musk also made news during the earnings call by simply not answering a question about ride sharing, leading to speculation Tesla could be considering its own operation. While the financials were the arguably the most important company news, reports of a Model S cyber hacking were more compelling fodder for Tesla followers. Researchers were able to attack the sedan and bring it to a stop, though they required access to the car first. Tesla says it already has deployed a remedy for the situation. On a lighter note, Tesla published a video of its metal charger prototype that autonomously uncoils like a snake to power up the company's vehicles, provoking plenty of humorous comments and comparisons. Watch it and decide for yourself. While some of this might seem trivial, much of Tesla's recent attention has been warranted. It's the first startup US automaker in decades to launch from nothing and actually gain traction in the market. Sure, Musk is a lightning rod and Tesla always seems to be in the spotlight. But amid all of the publicity, it easy to lose sight of the new reality: Tesla is a force. OTHER NEWS & NOTES 2016 Chevy Volt lights up 106 MPGe The Chevy Volt's vitals are looking healthier for 2016. The second-generation plug-in hybrid racks up a gaudy 106 miles per gallon equivalent, which is an increase of eight MPGe from the 2015 model. The new Volt can travel 53 miles on electricity, a significant jump from the 2015 Volt's 38-mile range. The new car also has a 420-mile total range when factoring in the capability of the gasoline engine, which is 40 miles greater than the current car offers.

Junkyard Gem: 1991 Ford Festiva with 317K miles

Most cars that make it to astoundingly high mileage figures tend to fall into one of two categories: engineering masterpieces that ended up being hard to kill (and got a lifetime of at least the most important maintenance items) or machines that inspired unquestioning love from owners willing to keep opening their wallets for decades to keep them on the road. Today's Junkyard Gem falls into neither of those groups; it's a penny-pinching Ford Festiva, one of the cheapest cars available in its time … and yet it cracked the magical 300,000-mile mark before getting discarded. So, a total of 317,207.3 miles over its nearly 30 years on the road. We just saw a discarded 1989 Honda Civic with a mere 308,895 miles on the clock, and this Festiva comes close to topping this 1993 Honda Civic DX. The highest-mileage junkyard car I've ever found (keep in mind that most cars before the middle 1980s had 5-digit odometers, and most cars this century have unreadable-in-the-boneyard electronic odometers) is this 1987 Mercedes-Benz 190E with an amazing 601,173 miles. This Mercedes-Benz 300D came close, with 535,971 miles. Detroit went to six-digit odometers late in the game, but this 1986 Olds Calais reached 363,033 miles, and this Ford Crown Victoria Police Interceptor reached the 412,013-mile figure thanks to a second career as a taxi. A Festiva surpassing the 300k mark, though, is not something I ever expected to see. These cars were sold as cheap, no-frills transportation, period. The MSRP on a base-level Festiva started at $6,620 in 1991, or about $12,610 in 2020 bucks. Not many cars could squeeze under that price at that time; the Subaru Justy could be purchased for $5,995, the Hyundai Excel 3-door hatch cost $6,275, and the Yugo GV (yes, it could still be obtained new as late as 1991) had a hilarious $4,435 price tag. Even the lowly Geo Metro, Pontiac LeMans, and Toyota Tercel EZ cost more than this Festiva. Still, this car came with snazzy pinstripes, now faded to near-invisibility by the Colorado sun. You can see the cover plate in the spot where the air-conditioning button would have gone, had the original buyer of this car been willing to squander precious dollars on such frivolity. Five-speed manual transmission, naturally. You could get an automatic in the Festiva, but anyone willing to spend that kind of money on extras would have been able to afford a much nicer Tercel EZ.
