INFINITI QX50 vs INFINITI QX55

Welcome to the ultimate showdown between two remarkable SUVs: the INFINITI QX50 and the INFINITI QX55. Both vehicles boast impressive features and unique styles, making them prime contenders for your next purchase. We feature both models at our INFINITI of Hoffman Estates dealership, and with this INFINITI QX50 vs. QX55 comparison, you can explore their design, performance, and more to help you discover which best suits your lifestyle.

Design and Dimensions

The first thing you notice about any car is its design. The  INFINITI QX50 and the  INFINITI QX55 offer sleek, modern looks but cater to different tastes. The QX50 has a more traditional SUV look with its upright stance and bold lines, making it an excellent choice if you prefer a classic yet contemporary style. The dimensions of the INFINITI QX50 are a length of 184.7 inches, a width of 74.9 inches (without mirrors), and a height of 66 inches.

The QX55 takes a sportier approach with its coupe-like silhouette featuring a sloping roofline that adds a dynamic flair. It’s slightly longer at 186.3 inches, but its width of 74.9 inches matches the QX50’s. The QX55’s height of 63.8 inches is marginally less, giving it a more aggressive and aerodynamic profile. Both models share a wheelbase of 110.2 inches, ensuring a stable and comfortable ride.

Interior and Comfort

On the inside, the QX50 has the option of leather seats and ambient lighting. Every QX50 has a comfortable, quiet cabin with a spacious rear seat and reclining seatbacks. The QX50’s interior design emphasizes practicality with its spacious cargo volume of 31 cubic feet, expanding to 65 cubic feet when you lower the 60/40-split folding rear bench seats.

The QX55’s cabin resembles the QX50’s, but INFINITI’s designers have chosen a simpler look instead of quilted leather. All three trims feature leather, with the top-of-the-range SENSORY boasting a softer semi-aniline variety. This variant also has black-stained maple wood trim and a faux-leather strip running from the console to the center stack. The QX55 sacrifices some cargo space for style, offering 26.9 cubic feet with all seats in place and 54.1 cubic feet with the rear seats down.

Performance and Powertrain

The QX50 features a variable compression turbocharged four-cylinder engine called VC-Turbo. It delivers 268 horsepower and 280 lb-ft of torque and pairs with an automatic continuously variable transmission (CVT). All-wheel drive is now standard. The engine effortlessly switches between high compression for cruising and low compression for acceleration. The INFINITI QX50 highlights comfort and luxury, offering a smooth ride on rough roads and highways. While providing minimal road feedback, the steering wheel is accurate and requires little effort.

The QX55 shares its turbocharged 2.0-liter four-cylinder engine with the QX50, and it has a CVT and all-wheel drive as standard. This SUV performs similarly to the QX50. The ride is smooth, making it perfect for commuting, even if it doesn’t have that athletic edge you might find in other options.

Fuel Economy and Environmental Impact

Fuel economy plays a significant role in choosing a vehicle, especially if you’re concerned about the environment. The good news is that the QX50 and QX55 deliver solid fuel economy for their class. Their EPA-estimated ratings are identical: 25 mpg combined, with 22 mpg in the city and 28 mpg on the highway. These figures make them solid choices if you demand a balance of power and efficiency, particularly for daily commutes and long drives. Both models require premium gasoline, so keep that in mind when budgeting for fuel costs.

Infotainment Systems and Other Technology

The 2025 versions of the QX50 and QX55 come with the INFINITI InTouch infotainment system. In the QX50, you get an 8-inch upper screen for navigation and a 7-inch lower screen for infotainment, apps, and climate controls. The manufacturer has equipped this dual-screen setup with wireless Apple CarPlay and Android Auto, so connecting your phone is straightforward and free of those annoying cables. The QX50 also has a 6-speaker (12-speaker in the SPORT trim) Bose system. Four USB ports and a wireless charging pad keep your gadgets topped up while you’re on the move.

The QX55 has a similar setup with the same screen sizes and features, but the main difference is the standard (on the ESSENTIAL and SENSORY trims) 16-speaker Bose Performance Series audio system. Both the QX50 and QX55 offer SiriusXM and in-car Wi-Fi. With connected services through the MyINFINITI app, you can start either model remotely, find it in a crowded parking lot, or get maintenance alerts. While both cars have similar tech, the QX55 gives you the more immersive audio experience.

Pricing and Value for Money

The 2025 INFINITI QX50 starts at $43,000, delivering a more budget-friendly alternative to the QX55, which begins at $50,150. The QX50 provides a well-rounded mix of luxury and practicality, offering a spacious interior and advanced safety features. The pricier QX55 boasts a sportier design and additional premium elements, particularly the Bose Performance Series audio system. If you prioritize a stylish, coupe-like SUV, the QX55 might justify the higher price, while the QX50 is ideal if you’re seeking a traditional SUV and exceptional value.
