马自达近日在日本发布了2017款马自达3改款车。2017款马自达3外观轻度改款，仅限于车头部分采用了重新设计的散热器格栅和新的前大灯，车尾采用了新的后保险杠。车厢内配备新的方向盘，仪表板装饰和车门内饰板，高规格版本提供电子驻车制动。另外新车增加了亮点进一步提升的全彩色抬头显示器。新车最大变化是动力传动系统的升级。新车首次提供了G-Vectoring Control（扭矩矢量控制系统），并且为应用于马自达全车系中的首款车型。这套系统通过调整发动机的扭矩输出，从而控制车辆的重心位移，使驾驶员无需进行转向矫正。采用该系统后，车辆在通过崎岖路面时的位移幅度将减少，能够提升车辆的舒适性和稳定性。新车还提供了i-ACTIV全驱系统，可预估前方路况，并可根据天气和驾驶员驾驶习惯提供进一步优化的前后轮扭矩分配。不过，该系统仅限于搭载2.2升柴油引擎的车型。除了这台引擎外观，该车还可搭载1.5升汽油和1.5升柴油引擎，而这两台引擎已经提供给2016款欧版马自达3车型。
Mazda3 facelift revealed for Japan
Mazda has taken the wraps off the refreshed Mazda3 family in Japan, where it is sold under the Axela name. Already available to order in the Land of the Rising Sun, the car comes with minor visual changes, limited to revised front end with redesigned radiator grille and new headlights. At the back we discovered only a new bumper.
Inside the cabin the Japanese manufacturer has put a new steering wheel, new decorations for the dashboard and the door cards, and an electric parking brake for the higher-spec models. A brighter, full-color head-up display with improved functionality has also been added.
Thankfully, more important changes have occurred under the skin of the Mazda3. The vehicle is the first from the company’s portfolio to get the G-Vectoring Control system that varies engine torque in response to steering inputs in order to provide integrated control of lateral and longitudinal acceleration forces. Or, in other words, Mazda used some code, a couple sensors, and a bit of ignition timing to make you feel ever-so-slightly more heroic going through a corner, as we discovered during our exclusive test of the system.
Back to the revised Mazda3, it also gets an i-ACTIV all-wheel-drive system, anticipating road conditions, weather, and the driver's intentions to provides “optimal distribution of torque to front and rear wheels.” This system is available only for the 2.2-liter diesel engine, which now benefits from reduced diesel knock.
Mazda will also offer a 1.5-liter petrol unit and a 1.5-liter diesel motor, already available in Europe from 2016MY.
