The segment for coupe-styled crossovers is growing rapidly thanks to the interplay between practicality and styling. Despite the sloping roofline, the QX55 has sufficient space for five passengers and, considering it's modeled on the QX50, the benefits of a spacious, elegant design carry over. We love the look of the modern interior, with higher trims showcasing more than just the familiar Nissan bits and bobs. However, the QX55 misses the 50's ultra-premium Autograph trim level. Dual-zone climate control and power accessories are standard - upgraded to tri-zone on the top trim - and the active noise cancellation is effective at promoting a quiet, serene cabin. Power-adjustable seats are also standard with Nissan's Zero-Gravity technology, while the Sensory gets ambient lighting and semi-aniline seating. There are two touchscreens for infotainment services, and while they are not awful, some rivals offer a much more user-friendly setup with larger displays and digital gauge clusters.
Like the QX50, the Infiniti QX55 is strictly a two-row crossover with seating for five passengers. It sits a bit lower than the QX50 with its coupe-like roofline, creating a noticeable decrease in interior volume (127.1 cubic feet in the QX55 compared to 133.3 cubes in the QX50). This results in less headroom and legroom, both in the front seats and the second row. That being said, the QX55 retains the sliding and reclining rear seat, making it easy for back-seat passengers to stay comfortable. Though the QX55 is less practical than its conventional counterpart, we commend Infiniti for minimizing the loss of usable space. We also have high praise for the Zero-Gravity seats, which offer great support on long trips.

The Luxe comes with leather upholstery in Graphite or Stone - both options are paired with Dark Aluminum trim, while the top Sensory model boasts more premium semi-aniline leather. You still have Graphite and Stone as options, but there's a striking Monaco Red two-tone option available too, and the Dark Aluminum interior trim is switched out for Black Open Pore wood accents. We enjoyed the sporty red cabin of our test model, though we wish Infiniti offered the QX55 with the stunning diamond-quilted seats in the QX50 Autograph.
As is the norm in the segment, cargo space in coupe variants is slightly diminished over the regular crossover models, and the QX55 is no different. Where the QX50 has an impressive 31.4 cubic feet for cargo, the QX55 has just 26.9 cubes behind the second row. It's still more than enough for grocery shopping for the small family, and more than you get from the Audi, BMW, or Mercedes SUV coupes. Fold down the back row and you have 54.1 cubes to play with, which is around ten cubes less than the QX50. The trunk has cargo net tie-down anchors as standard for added convenience, as well as duplicate levers to fold the seats in the second row and cargo area.
Small items can be stored around the cabin in door pockets, a standard glovebox, and under the center armrest. There are dual front and rear cupholders and bottle holders, and seatback map pockets for all trims.

There's loads of value to be had from even the base model in the range, with features like intelligent key and push-button start, dual-zone climate control, and eight-way power-adjustable front seats being standard. From the mid-range Essential model, you get climate-controlled seats with memory function and a heated steering wheel. The top-spec Sensory trim gets tri-zone climate control, enhanced interior ambient lighting, but power lumbar settings for the front seats are standard across the range.
In terms of safety features and driver assists, entry-level trims have cruise control and high beam assist, as well as brake assist, blind-spot warning, rear cross-traffic alert, and forward collision warning. Forward emergency braking with pedestrian detection, lane departure warning, the brand's ProPILOT assist, blind-spot intervention, and rear automatic braking complete the standard consignment on the Luxe. A surround-view monitor and traffic sign recognition are added to the Essential trim, and the fully-loaded Sensory model gets a head-up display.
Infiniti didn't change much from the QX50 when designing the QX55's infotainment system. Every trim includes Infiniti's InTouch setup with an eight-inch upper and a seven-inch lower touchscreen. Our complaints about this configuration are well documented and boil down to crunchy graphics and a confusing interface with too many physical buttons and on-screen menus. As an improvement, Infiniti now offers wireless Apple CarPlay as standard, which takes over the top screen while freeing the lower screen to display audio information without having to exit back to the stock user interface. Android Auto is standard, too, but requires a USB cord.
All QX55 models include Wi-Fi hotspot capability and four USB ports (one USB-C and three USB-A). Built-in navigation and a Bose Performance Series premium audio system with 16 speakers are installed on Essential and Sensory trim levels. We found the Bose system to sound fine, but not the best we've heard at this price
