The previous generation QX50 has been on sale in China since 2015 and in other countries and regions since 2013, and it is equipped with a 3.7-liter VQ37VHR engine (325 hp) in foreign countries and a 2.5-liter VQ25HR engine (235 hp) in China.
 
The second-generation QX50 was officially released at the 2017 Los Angeles Auto Show, even from the beginning of the listing, the QX50 is only 4 years old, and the domestic sales are only three years, compared to some models that are often sold for 5-8 years, the QX50 is actually early this time.
 
The second-generation QX50 is a real generational change, and it is a game-changer in many ways. The first generation uses a naturally aspirated engine, while the second generation uses Nissan's newly developed variable compression ratio engine, codenamed KR20DDET. At present, many car manufacturers are developing variable compression ratio engines, and Nissan is the first mass-produced variable compression ratio engine, the compression ratio can vary from 8:1 to 14:1, theoretically it is possible to take into account both performance and fuel economy, but the change of the engine in daily driving is not felt.
 
The second-generation QX50 is divided into two versions, high-power and low-power, the low-power version has a maximum horsepower of 245 hp and a maximum torque of 380 Nm, and only two low-end models are available, and it is front-wheel drive, and the high-power version is 272 hp and 380 Nm, and the drive form is a timely four-wheel drive. In addition to the different power tuning, both the high and low power will be paired with an analog 8-speed Xtronic CVT transmission, after Motor Trend testing, the high-power version can run in 0-96km/h acceleration in 6.4 seconds, about a second slower than the previous generation 3.7 model, but there is not much difference in the class, the new Q5 is 5.9 seconds, the new X3 30i is 6.3 seconds.
 
The steer-by-wire on the first-generation QX50 has always been controversial, because its steering feel is different from hydraulic assistance and electronic assistance, and it feels like there is a thick layer of sponge between the steering wheel and the wheels, especially the small steering, which requires getting used to in daily driving, but it is not a big problem, but when driving intensely, the shortcoming of steering blur will be magnified and become a deduction.
 
On the second-generation QX50, this DAS steering system has been improved to 2.0 version, its feel is already very natural, but when fine-tuning the direction, its positive force is still a little strange, or it will be distorted, but there is no need to be too entangled in this steer-by-wire system, because only the top model is equipped, and other models are still electric power steering, and QX50's power steering tuning is more comfortable, and it will not bring any driving pleasure.
 
Both the exterior and interior are the highlights of this generation of QX50, with a sense of design throughout the car inside and out, and there are many places where the engineers give in to the designer's philosophy. The interior is a big plus for QX50, although it is the same luxury brand, but the Japanese have always taken a different route from the German system, QX50 also uses a lot of leather materials, including not only Alcantara, but also Toray's new materials, the feel is also very good, different series of suits are very attractive, in the same class QX50 interior has enough competitiveness.
 
Infiniti, as Nissan's high-end brand, also plays Nissan's normal level in terms of seats, the front row is known as the "zero gravity seat", the ride is quite comfortable, and the space performance of the second row of seats is the normal level of the same level, but the backrest and front and rear of the second row can be adjusted, which is also a plus.
 
This generation of QX50 has done a very good job in both sound insulation and shock filtration, in addition to the normal sound insulation project, it also uses ANC's interior noise reduction, wind noise and road noise are well isolated, it also has a set of electronically controlled engine pads, which is helpful for reducing the vibration of the engine, but this engine will still have noise coming in when pulling the speed, and because the sound insulation of the compartment is better, so the suspension action is relatively obvious, when the action is relatively large, You can hear it working.
 
This generation of the QX50 has not yet participated in crash tests, but as the first work after the end of the collaboration between Infiniti and Mercedes-Benz, it is not expected that safety will lag behind its peers, and the previous generation QX50 also performed well in the reliability survey of US consumer reports, and the reliability is expected to be more optimistic.
 
This generation QX50 participated in the IIHS crash test, but only the frontal offset crash and side impact tests, and the rest of the items did not participate, while the previous generation QX50 performed well in the reliability survey of the American "Consumer Reports" and was more optimistic about the expected reliability, but the "Consumer Reports" of the United States only gave a score of 3 out of 5 for expected reliability, which can only be considered moderate.
