英菲尼迪将在几周后的洛杉矶车展发布2019款QX50，近日该车图片和细节提前曝光。这款车将搭载世界首台量产版可变压缩比引擎。按照车厂的说法，这台VC-Turbo引擎“在内燃机引擎设计上是一个突破”。这台2.0升涡轮引擎可以通过调整压缩比进一步优化动力和燃油经济性，使这台汽油引擎能达到四缸柴油引擎的扭矩输出。该引擎功率200千万/268马力，扭矩380牛米，使其功率达到同级引擎最佳水平。在全驱情况下车辆0-96公里/小时加速时间仅需6.3秒，最高时速230公里。而前轮驱动车型的综合油耗为27英里/加仑（百公里油耗约合8.71升），全轮驱动车型为26英里/加仑（百公里综合油耗为9.04升）。相对于搭载V6引擎的老款车型，新车燃油经济性提升了35%。这款车还可提供CVT变速器。2019款QX50采用全新平台，车身刚性比老款车提升23%。同时，它的内部空间更宽敞，车身长度为4693毫米，高度1679毫米。行李箱容积从老款车的31.6立方英尺（约合894.8立升）提升至37立升（约合1047.7立升），如果将后排椅背放平可提升至60立方英尺（约合1699立升）。这款车配备了日产新的ProPilot辅助驾驶系统，只需按一下按键就可以在单车道高速路上让车辆自动完成加速、制动和转向这些动作。目前还不知道新车价格，但该车预计将于明年初上市。
2019 Infiniti QX50 Debuts With A Sculpted Design, VC-Turbo Engine
In just a few weeks, doors will officially open to the 2017 L.A. Auto Show. And when they do, amongst the many vehicles that will undoubtedly be on display, Infiniti will be debuting its "most advanced," "most compelling" vehicle to date – and no, we’re not talking about the flagship sedan concept.
This is the new Infiniti QX50. Under the hood is the world’s first production-ready variable compression ratio engine. The VC-Turbo unit, which was previewed initially in 2016, is what the company calls "a breakthrough in combustion engine design." The 2.0-liter turbocharged unit is able to adjust its compression ratio to optimize both power and efficiency, giving it similar torque to a four-cylinder diesel engine.
Output is rated at 268 horsepower (200 kilowatts) and 280 pound-feet (380 Newton-meters) of torque, which makes the VC-Turbo engine best in class in terms of power. Sprinting to 60 miles per hour in dealt with in just 6.3 seconds with all wheel drive, not that it matters, and top speed is listed at 143 mph (230 kmh). The new VC-Turbo engine is expected to deliver 27 mpg combined with a front-wheel-drive configuration, and 26 mpg combined with all-wheel drive equipped. The QX50 delivers 35 percent improvement in fuel efficiency over the previous V6. All that newfound performance is paired to a CVT.
The 2019 QX50 is built atop a brand-new platform that’s 23 percent more rigid than the outgoing model. It allows for more room in the cabin, too. The SUV measures in at 66.1-inches (1,679 millimeters) tall, and stretches out to 184.8 inches (4,693 millimeters) long. Trunk volume expands from 31.6 cubic feet in the outgoing model to 37 cubic feet, growing to 60 cubic feet with the rear seats folded flat.
Equipped with Nissan’s new ProPilot assist – the same technology available on the 2018 Rogue – the QX50 assists in acceleration, braking, and steering input during single-lane highway driving, all at the push of a button. No word on pricing or availability just yet, but expect the new Infiniti QX50 to go on sale sometime early in 2018.
