INFINITI QX55 vs. Lexus RX 350

Crafted for Comfort

From the moment you settle into the driver’s seat, your vehicle’s cabin should feel like a tailored escape: quiet, confident, and refined. In luxury crossovers like the INFINITI QX55 and the Lexus RX 350, comfort begins with the details. Both models offer thoughtful amenities designed to elevate every mile, including:

• 8-way power front seats
• Heated front seats
• Dual Zone Automatic Temperature Control

But step inside the QX55 and refinement goes a few steps further. It features standard leather-appointed seating with 4-way power lumbar support, delivering personalized posture and plush comfort on every drive. The QX55 also includes driver’s seat memory, automatically adjusting to your preferences after someone else takes the wheel. In contrast, the RX 350 starts with synthetic NuLuxe® upholstery, and memory seating is only available as an upgrade.

Spacious by Design

Luxury isn’t about features—it’s about freedom. When you’re settling in for a weekend getaway or loading up for the next family adventure, space matters. The INFINITI QX55 delivers a more generous interior than the Lexus RX 350, giving every passenger room to breathe and every journey room to expand.

Beyond comfort, the difference is also about capability. Both models offer split-folding rear seats, but the QX55 goes further with up to 54.1 cubic feet of cargo space, compared to 46.2 cubic feet in the RX 350. Whether it’s luggage, sports gear, groceries, or unexpected extras, the QX55 adapts with ease.

Confidence in Motion

The true test of a luxury crossover is how it handles the unexpected, effortlessly adapting to less-than-ideal conditions. Every INFINITI QX55 comes equipped with a responsive Continuously Variable Transmission (CVT) with manual shift mode, designed to deliver seamless power and fluid acceleration. The RX 350, on the other hand, features a traditional 8-speed automatic transmission.

INFINITI’s standard Intelligent All-Wheel Drive (AWD) automatically shifts torque between the front and rear wheels to maintain grip and confidence as conditions change. Meanwhile, the RX 350 comes standard with front-wheel drive, with AWD offered as an option. If you’re looking for a driving experience that’s composed, capable, and ready for whatever lies ahead, the QX55 is for you.

Performance With Purpose

Power is always part of the equation, although sometimes more is just. . . more. The INFINITI QX55 and the Lexus RX 350 feature turbocharged 4-cylinder engines that deliver a balanced output of over 265 horsepower. The result? Confident acceleration, effortless highway merging, and composed performance where it counts: in real-world driving.

To fairly assess efficiency, we compared both models equipped with all-wheel drive:

• INFINITI QX55: EPA-estimated 22 city/28 highway MPG*
• Lexus RX 350: EPA-estimated 21 city/28 highway MPG

At first glance, a one-mile-per-gallon advantage may seem minimal—until you consider how it adds up over time. In urban settings with stop-and-go traffic, that extra efficiency can make a tangible difference at the pump and during long commutes.

Innovation With Intention

Forward-thinking features elevate every moment behind the wheel. While the QX55 and the RX 350 deliver premium amenities, INFINITI goes a step further, making standard what others—like Lexus—reserve for top-tier trims. The QX55 includes thoughtful touches like:

• Wireless charging
• 4 USB ports
• Siri® Eyes Free
• HomeLink® Transceiver

Together, these elements transform the cabin into a refined, tech-savvy sanctuary. It's more than comfortable; it's purposefully designed to enhance your daily drive.

Protection With Precision

Few technologies matter more than those that safeguard what matters most. Advanced driver-assist features are designed to respond when the unexpected occurs—and sometimes even before. The QX55 and the RX 350 offer a robust suite of safety features that support your instincts behind the wheel, including:

• Lane Departure Warning
• Blind Spot Intervention®
• Rear Cross Traffic Alert
• Forward Collision Warning
• Rear Automatic Braking
• Adaptive Cruise Control with traffic stop-go

While both models are well-equipped, the INFINITI QX55’s Predictive Forward Collision Warning not only watches the car ahead of you—but the one beyond that—giving you added time to react. Paired with Forward Emergency Braking Mitigation, the QX55 helps reduce the risk of a collision when traffic suddenly slows.
