英菲尼迪将在今年北美车展发布QX50概念车，该车将成为最吸睛车型。虽然这是一辆概念车，但比先前在巴黎和北京车展亮相的QX Sport Inspiration概念车更接近量产版。这款QC50概念车外观设计抢眼，同时比目前在售的QC50系列更好的保留了车厂设计风格。车头最吸引人的是它的双拱形镀铬格栅，而车身侧面的每一块面板都带有曲线和折线。这种设计突出了时尚和动感，该车的车顶逐渐向后倾斜，尾窗设计很有曲线感。车厢前翼设计使这辆跨界车很有运动感，而车底金属护板进一步提升了车辆越野行驶能力。英菲尼迪暗示，量产版车型，也就是下一代QX50将搭载新的VC-Turbo引擎，这台2.0升涡轮直列四缸引擎可以调整活塞冲程以改变压缩比，同时进一步优化功率输出和效率。预计该引擎功率为200千瓦/268马力，扭矩390牛米。但车厂表示，该引擎在相同功率输出情况下燃油经济性比V6引擎提升27%。该车还将采用ProPilot，这是日产和英菲尼迪采用的半自动驾驶系统，可导航车辆通过路口而无需驾驶员干预。

 

Infiniti QX50 Concept is our best look yet at the brand’s next crossover

The Infiniti QX50 Concept that debuts at the 2017 Detroit Auto Show will be our best look yet at the design of the luxury marque’s next mid-size crossover. Though this is still a concept, it’s far closer to reality than the previous QX Sport Inspiration show cars we saw at the Paris and Beijing shows earlier this year.

 

This latest Infiniti QX50 Concept has striking, expressive styling that’s far more in keeping with the brand’s current design trends than the dated QX50 that is currently on sale. A giant interpretation of Infiniti’s double-arch mesh chrome grille dominates the nose, while almost every body panel is bisected by curves and creases. As is the modern trend for both styling and aerodynamics, the QX50 Concept’s roofline descends noticeably toward the rear, and the rear window is notably angled. A cabin-forward stance lends the crossover a sporty look, while metal skid plates at either end connote a modicum of off-roading ability.

 

Infiniti hints that the production version of this vehicle, the next QX50, could use the company’s new VC-Turbo engine. It’s a 2.0-liter turbocharged inline-four, but its computer can alter the piston stroke to change the compression ratio and thus optimize for efficiency of power. The engine is expected to produce 268 horsepower (200 kilowatts) and 288 pound-feet of torque (390 Newton-meters), but Infiniti says it’ll be 27 percent more fuel efficient than a V6 engine with equivalent power.

 

The QX50 Concept will also include some ProPilot technology. That’s the name Nissan and Infiniti use for semi-autonomous systems that will soon be able to navigate intersections without driver interaction.
