The next is the Natural Sound Smoother. Recently introduced on the SKYACTIV-D 1.5 in the Mazda 3, it has now been adapted for Mazda larger diesel. The technology uses a damper placed in the hollow part of each piston pin to stifle diesel knock in the 3.5kHz range. This is the engine noise most conspicuous in the cabin and typically experienced when starting from a standstill or accelerating gradually. Natural Sound Frequency Control, meanwhile, complements the Natural Sound Smoother by supressing the other three critical frequency bands (1.3kHz, 1.7kHz and 2.5kHz) where diesel powerplant components typically vibrate loudest. It does so by deviating the engine timing ever so slightly (in 100 microsecond units), thereby causing the pressure waves produced before, during and after combustion to cancel each other out. This reduces combustion-induced vibration and the resulting cabin resonance.
The Mazda Kai Concept compact hatchback heralds a new generation of Mazda cars. Featuring the next-generation SKYACTIV-X gasoline engine, SKYACTIV-Vehicle Architecture and a more mature expression of the KODO design language, the model embodies the technology, engineering and design concepts that will define the next generation of Mazda cars. Refinements in all areas of dynamic performance have produced a dramatically quieter, more comfortable ride and an enhanced performance feel. The Mazda Kai Concept features muscular, solid proportions and its form is brought to life by a delicate flow of reflections over the body sides. Developers of the all-new Mazda CX-5 aimed to take the emotional appeal and powerful vitality the carmaker has pursued with its KODO - Soul of Motion designs to a yet higher level by creating a fresh expression of beauty that appeals to mature sensibilities. Aiming for a unique design only Mazda could produce, the development team started with a simple yet honed form free of non-essential elements, as is common in traditional Japanese crafts, choosing "refined toughness" as the design keyword.
The benefits are numerous. By optimising the vertical load on the tires to the given conditions, it keeps the vehicle on its intended path while significantly reducing the need for steering correction. The communication between driver and car is simply more efficient, which instils confidence and reduces driver fatigue. And safety, since a relaxed driver is also more alert. It also enhances comfort, since the smoother, "natural" transition of g-forces supresses occupants head and body movement. Developers looked closely at human perceptions to come up with a system that reacts so quickly as to be indiscernible. GVC therefore not only enables better control of the car than is possible for a person on their own, it also extremely subtle about it. The aforementioned deceleration force normally amounts to a g-force on the 2017 Mazda 6 that is scarcely distinguishable to occupants.
