Now Mazda has gone a step further with its human-centered philosophy. To gain a systematic understanding of what exactly gives people a satisfying and exhilarating experience behind the wheel, the company began testing and assessing how they respond. It determined, for example, that a relaxed posture makes a person more responsive and less prone to fatigue. Debuting in Europe as standard equipment on the 2017 Mazda 6 and 2017 Mazda 3, the first system in the new SKYACTIV-VEHICLE DYNAMICS line-up is G-Vectoring Control (GVC). GVC is a product of Mazda pursuit of smooth transitions between the g-forces produced when accelerating, braking and turning. It the only system of its kind that adjusts engine torque in response to steering wheel action to achieve smoother and more efficient vehicle behaviour, providing unified control over lateral and longitudinal forces to optimise the load on each wheel.
Both SKYACTIV-D 2.2 versions feature a sequential twin turbocharger, delivering outstanding toque without turbo lag, as well as the fuel-economy advantages of optimum combustion timing, specially shaped pistons, multi-hole piezo injectors and more. These unconventional diesels are now more responsive and quieter than ever, too, with three new systems for the SKYACTIV-D 2.2 making their debut on the 2017 Mazda 6. The first, High-Precision DE Boost Control, enhances boost pressure control and enables finer fuel injection adjustments to sharpen the response to the accelerator, particularly under light load urban conditions or when merging onto a busy motorway. It thus achieves accurate and swift torque generation at the slightest touch of the accelerator pedal for smooth, linear acceleration with minimal shock and vibration - more like a naturally aspirated petrol engine. The car accelerates as intended, refining the Jinba-Ittai communication and feedback between the driver and car. It a well-oiled relationship.
i-stop is Mazda innovative, intelligent idle-stop system. Standard equipment on the all new Mazdas including the 2017 Mazda 6, it uses combustion energy for the restart. In addition to saving fuel, this enables some of the fastest restarts in the industry: 0.35 seconds for SKYACTIV-G petrol engines and only 0.40 seconds on SKYACTIV-D diesels. i-stop uses a refined control module to switch off the engine in the ignition/expansion stroke (petrol) or compression stroke (diesel), the optimum cycles for restarting. In fact, i-stop actually waits for the moment the cylinders are in the ideal restart position. And it only takes a spilt second.
Smart Brake Support (SBS) also widens its speed range for automatic braking, in this case from 15-145km/h to 15-160km/h, thanks to the forward sensing camera, which supplements the existing 77GHz microwave radar. SBS monitors preceding vehicles, first sounding an audible warning should it detect a hazardously closing gap and pre-filling the brakes, applying them should the driver fail to respond. Traffic Sign Recognition (TSR) also utilises the new camera to identify speed limit and "no entry" signs, immediately notifying the driver via the Active Driving Display. It warns drivers with visual and audible alerts should they exceed the limit.
