3 Answers
The differences between the FX35 and QX70 are as follows: 1. FX35: The FX35 is now known as the QX70; the EX is now called the QX50. The FX35 features an older single-intake engine, while the QX70 comes with the same VQ37HR dual-intake engine as the G37, offering significant improvements in power. The braking system has also been upgraded, and the front grille has been changed from a wave pattern to straight lines. 2. QX70: This is the newer version of the FX35, a high-end SUV that emphasizes value for money. In terms of handling, due to its heavy body and 3.7L naturally aspirated engine, it starts very steadily and feels like it has no speed limit once it gets going. The exterior design follows a sports car style, with a long front face, aggressive headlights, and large 21-inch wheels that look very cool.
I drove the Infiniti FX35 for several years, and that car was really great—packed with power, and the V6 engine delivered an exhilarating sense of acceleration. However, the QX70 is a complete upgrade—its design is sleeker, less angular than the FX, and the seats are more comfortable. Technologically, there’s significant progress; the QX70 adds touchscreen navigation and adaptive cruise control, greatly improving safety. In terms of price, the FX35 is cheaper in the used car market, but the QX70 holds its value better. Maintenance-wise, the older FX had fewer minor issues. Overall, the QX70 is the evolved version, more suitable for daily family use. If the budget allows, I’d definitely recommend the latter.
From a technical perspective, the core differences between the FX35 and QX70 lie in engine tuning and suspension systems. The FX35's 3.5L V6 outputs around 275 horsepower, leaning towards sportiness; the QX70 optimizes fuel efficiency with a softened suspension for greater comfort while retaining handling capabilities. Their transmission systems are similar, but the QX70 incorporates adaptive functionality to enhance responsiveness. Electrical systems differ significantly, with the QX70 featuring more standard electronic assists like blind-spot monitoring. In terms of maintenance costs, QX70 parts may be slightly more expensive but have lower failure rates. Overall, the QX70 represents a more mature iteration.
