What engine does the Infiniti QX50 use?
3 Answers
Infiniti QX50 is equipped with two types of engines: a low-power version 2.0-liter turbocharged engine and a high-power version 2.0-liter turbocharged engine. The Infiniti QX50 is a mid-size luxury SUV under the Infiniti brand, with dimensions of 4705mm in length, 1903mm in width, and 1678mm in height, and a wheelbase of 2798mm. In terms of configuration, this vehicle is equipped with features such as Distance Control Assist System, Enhanced Intelligent Brake Assist, Dynamic Pedestrian Detection Warning System, Predictive Forward Collision Warning, Back-up Collision Intervention, Back-up Collision Warning, and Blind Spot Warning System.
I've studied the powertrain of the Infiniti QX50, which comes standard with a 2.0-liter VC-Turbo variable compression ratio engine across the entire lineup. The most impressive feature of this engine is its intelligent switching capability between compression ratios ranging from 8:1 to 14:1. At low compression ratios, it delivers strong explosive power with 272 horsepower for decisive overtaking; at high compression ratios, fuel consumption drops significantly, achieving 7L/100km during highway cruising. The transition between compression ratios is completely imperceptible during driving, with very linear power delivery. This technology even won the Ward's 10 Best Engines award. In practical use, it's 20% more fuel-efficient than the previous V6 engine while delivering faster acceleration. During my test drive, I paid special attention to the cold start sound – the turbo engagement is very smooth, without the abruptness found in some German cars.
As an owner of the QX50, I have a deep understanding of the high-tech engine in my car. During daily urban commuting, the compression ratio stays at 14:1, and it runs smoothly on 92-octane gasoline, with a full tank covering over 600 kilometers. When tackling mountain roads on weekends, stepping hard on the throttle instantly adjusts the compression ratio to 8:1, unleashing the full 380 Nm of torque, delivering an immediate push-back sensation when exiting corners. The 4S shop technician mentioned this engine is unique globally, emphasizing the need for 0W-20 full synthetic oil during maintenance and more frequent carbon deposit cleaning. After two years of use, the most impressive aspect is the perfect balance between power and fuel efficiency—even with aggressive driving, the fuel consumption stays around 11 liters, making it ideal for family use.
