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.

As someone who loves car styling, I pay attention to design changes. The FX35 has a bold front face with a square and impactful grille, while the QX70 is much more rounded, with smoother lines and modernized headlights and rear. Inside, the QX70 uses higher-quality materials, with less plastic feel, creating a more luxurious overall ambiance. The color options are also trendier. When driving, the QX70 offers stronger visual impact, clearly aligning more with modern aesthetics. Small functional improvements, like optimized trunk space, are quite practical. In summary, the visual differences are significant.

When on a tight budget, I consider cost comparisons. The used FX35 typically prices below 10K, suitable for beginners; the QX70 is newer with a higher starting price but better resale value. For maintenance, FX35's older parts are cheaper and easier to replace, while QX70's integrated tech may mean pricier components. Fuel consumption is similar, with QX70 slightly more efficient. Insurance and depreciation rates make QX70 more cost-effective long-term. Reliability data shows early FX35s had minor electrical issues, which QX70 has reduced. The choice depends on your budget, but QX70 offers better value.

Looking back at the history of Infiniti models, the FX35 was a popular SUV representative in the 2000s, known for its performance. By 2013, the brand unified its naming to QX70, with changes not limited to the name: the engine was fine-tuned, suspension software was upgraded, and safety features like lane departure warning were added. The infotainment system was revamped to keep the driving experience up-to-date. This reflects the brand's shift toward technological luxury. Now that the FX35 is discontinued, the QX70 as its successor is more durable. At its core, the QX70 retains the essence but is more modern.
