Mazda6 diesel engine delayed over low performance, still coming

Oh Mazda... we had many hopes for the promised diesel four-cylinder in the Mazda6, but those have remained largely unfulfilled, as the oil-burning powerplant has failed to appear on dealer lots following its 2012 LA Auto Show announcement. Despite engineering issues that forced the company to announce that the program was delayed back in September 2013, Mazda remains adamant that the 2.2-liter Skyactiv-D is still coming to our shores. "We're still very much committed to diesel," Mazda's North American CEO, Jim O'Sullivan, told Automotive News. "We are still working on getting the performance aspects up to where we want them, and we do have a plan – an engineering road map – to get it done." According to AN, Mazda's initial plan with the 2.2-liter diesel was to build an engine so clean it could get by without an aftertreatment system, which generally accounts for the price premium of diesel engines versus their gas counterparts. The new system has come with performance issues, though, necessitating the delays. "If [we were] a commodity brand and didn't care about that, it would be on the market right now," O'Sullivan told AN. "But I know the people were expecting something from us, expecting certain drive characteristics and performance, and I didn't want to disappoint them." While O'Sullivan's defense of the diesel Mazda is admirable, the exec stops short of giving us an indication of when the new engine will finally arrive.

Recharge Wrap-up: Mazda, Toyota earn environmental awards

Electric mobility nonprofit Drive Oregon has launched a campaign to invite the electric car industry to perform testing in the state. The campaign tells companies to, "Test Drive the Future in the Living Lab," citing Oregon's density of EV owners and charging infrastructure, varied terrain and climate, funding opportunities, and the state's technological reputation as the "Silicon Forest." Plus, as Drive Oregon Executive Director Jeff Allen, points out, "if you really screw things up here, it doesn't make as much noise as it would in California." Already, Jaguar Land Rover has announced plans for an Innovation Incubator in Oregon. Read more at Green Car Reports. Mazda's new paint system has won the Prime Minister's Award in the category of Manufacturing and Production Process at the 6th Monodzukuri Nippon Grand Award ceremony. Mazda's Aqua-tech paint system significantly reduces emissions of volatile organic compounds (VOCs) and CO2. The Aqua-tech system uses a water-based color basecoat and a urethane clear coat to reduce VOC emissions by 57 percent. It consolidates the painting process and reduces energy in paint-booth air-conditioning and flash-off processes to reduce energy consumption. It also allows Mazda to create such colors as Soul Red, which looks quite nice on the MX-5 Miata. Read more at Green Car Congress, and learn all about the Aqua-tech paint process from Mazda. The Toyota Mirai has received a 2015 Environmental Award from Austrian automobile club ARBO. The hydrogen fuel cell car took the prize in the category of Current Innovative Environmental Technologies. "At Toyota, we believe that various technologies will co-exist, ranging from EVs to hybrids to the most innovative of all, the fuel cell car," says Gerald Killmann, Vice President R&D of Toyota Motor Europe, in a comment thanking ARBO. "Mirai is a core component of Toyota's vision for a sustainable mobility society, one that allows us all to move freely in comfort and safety in an environmentally friendly, sustainable manner." Read more in the press release below. Vienna, Austria- November 5th - The Austrian automobile club ARBO* (Auto-Motor und Radfahrerverbund Osterreiche) has awarded the Toyota Mirai with the "2015 Environmental Award". This Award was received during a gala ceremony held yesterday in Vienna, where the Toyota Mirai was awarded in the category of "Current Innovative Environmental Technologies" . The jury consisted of ARBO automotive experts.

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.
