2025 Lexus NX vs 2025 Infiniti QX50
Finding the Winning Formula for A Luxury SUV in Phoenix: Infiniti QX50 vs Lexus NX
The 2025 Lexus NX has arrived with a big refresh, competing even more strongly against the 2025 Infiniti QX50. Which one has the winning formula? For that matter, which one should you test drive first?
Performance
If price is your main concern, here’s what you should know. With just three trim levels, the 2025 Infiniti QX50 Pure, Luxe, and Sport provide only 3 price points between $43,000 MSRP to $51,200 MSRP. There are 10 trim levels for the Lexus NX between $41,990 MSRP to $52,365 MSRP. The NX 450h models bring the number of trim levels to 13.
Shoppers can save money with the Lexus NX 250 and its front-wheel drive. There’s not much price difference between the entry level Infiniti QX50 and the NX turbo. Basically, you can get better horsepower with the Lexus NX 350 or 350h. There is no performance upgrade with Infiniti, despite price increases.
NX 350 turbos generate 275 horsepower and 317 lb-ft of torque. The 2025 QX50 in Phoenix also has a turbo, but it produces 268 horsepower and 289 lb-ft of torque.
If you want money-saving hybrid capability, the only choices are at your Phoenix Lexus dealership. You can choose the Lexus NX 350h or one of its trim levels to get excellent horsepower and incredible fuel efficiency.
Or, if you want to enjoy electric driving range and gas engine convenience, you can choose the NX 450h+ AWD and NX 450h+ F Sport Handling AWD. This powertrain creates up to 304 horsepower for a really speedy ride. 
Lower Operating Costs
If you are looking for the lowest operating costs, Lexus has the better choices. The NX gas powertrain can claim the best standard engine gas mileage. It can earn 25 mpg in the city and 32 mpg on the highway. That’s 28 mpg combined. The Infiniti QX50 earns 25 mpg in combined driving, and there’s no option to get better gas mileage.
The NX 350h earns 41/37/39 MPG (city/highway/combined). If you look at the two SUVs using the government fuel economy.com, you will see that the NX promises significant savings.
If you step up to the NX 450h+, you get a plug-in hybrid that can go up to 37 miles. That’s an emissions-free daily commute. Plus it earns an 84 MPGe rating with hybrid and electric miles combined. If you want to know more, use this contact form to ask your questions.
Better Long Term Ownership
Superior Reliability and Long-Term Ownership:
Whether you are looking at JD Power or Consumer Reports, you will find that Lexus consistently ranks very high in reliability studies, often topping the charts. Recently, Consumer Reports rated the Lexus NX's reliability 22 points higher than the QX50.
Furthermore Lexus vehicles generally have a strong reputation for lower maintenance costs and excellent resale value. Plus the brand has a wider dealer network. There are over 23% more Lexus dealers than INFINITI dealers, which can make service and warranty support more convenient, if you are traveling far from Earnhardt Lexus, your Phoenix Lexus dealer.
Lexus and Infiniti warranties are roughly the same; however, the hybrid (350h) and plug-in hybrid (450h+) have a warranty that can provide up to ten years of coverage for hybrid or electric components and the related batteries.
At Edmunds, Lexus is one of their top ten luxury brands for 2025. Infiniti is an honorable mention.
Interior and Technology
Of course, most of us don’t prioritize efficiency or long-term costs when we are shopping for a luxury SUV. We want a cabin full of amenities and top technologies.
Rest assured, that the Lexus NX comes packed with everything you’d expect. Plus Lexus is renowned for its efforts in creating serene and quiet cabin environments. The NX utilizes sound-dampening materials, active noise cancellation technology, and aerodynamic design to minimize road and wind noise.
As for technology, the NX features a responsive and user-friendly touchscreen infotainment system (available in 9.8-inch or 14.0-inch sizes) with wireless Apple CarPlay and Android Auto. This is generally considered a significant improvement over Lexus's previous touchpad-based systems and offers a modern interface that is easily the most up-to-date in this Infiniti QX50 comparison.
Tech geeks may wonder about driver assistance. Well, the NX includes advanced safety features that match or exceed the Infiniti. For instance, there’s a driver alert monitor (not offered on QX50) and Parking Support Brake, which automatically applies brakes when backing near traffic (QX50's Rear Cross Traffic Alert doesn't automatically brake). Check out this 2025 review for more details.
