英菲尼迪在几周前发布了2019款QX50的官图。而在近日，车厂在洛杉矶车展正式发布了QX50，车厂形容这款车是“最先进的”和“最具吸引力”的车型。而这款新车最大的亮点就在于其搭载了一台可变压缩比的2.0L涡轮增压引擎。这台世界首台量产版可变压缩比引擎VC-Turbo最初是在2016年亮相的，它采用了“突破性的内燃机引擎设计”，可通过调整压缩比使动力和燃油经济性达到最佳优化，使其扭矩输出达到四缸柴油引擎水平。该引擎最大功率200千瓦/268马力，扭矩380牛米，达到同级引擎最大功率和扭矩。全驱版本0-96公里/小时加速时间6.3秒，最高时速230公里。QX50前驱版本平均油耗27英里/加仑（百公里油耗8.71升），全驱版本26英里/加仑（百公里油耗约合9.04升）。由于车辆采用全新平台，因此车身刚性提升23%。其内部空间也更宽敞，车身高度1679毫米，长度4693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.
