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.
Mazda applied every aspect of its human-centred philosophy to the all-new CX-5, enhancing the already acclaimed design of the current model. The result is cabin comfort that makes every trip a delight for all occupants. The cockpit zone is designed around the ideal driving position, with all controls and switches laid out where the driver can operate them with natural hand or foot movements. To improve usability, the floor console was raised and the shift knob positioned 60mm (automatic) or 40mm (manual) higher than on the current model.
Short for "Intelligent Energy Loop", Mazda fuel-saving i-ELOOP brake energy regeneration system was the world first such passenger car technology to utilise a capacitor to store electricity recovered during braking. Mazda focused on the recurring deceleration and acceleration cycle of everyday driving conditions. Determining that a typical deceleration phase lasts only about 10 seconds, the company adopted an electric double-layer capacitor (EDLC) to quickly capture and temporarily store the recovered electricity rather than a dedicated lead-acid starter battery or lithium-ion unit.
