The 2014 Infiniti QX50 (formerly known as the Infiniti EX) gets a new name, but otherwise returns with no significant changes.

Luxury automakers often try to inject sporting qualities into their otherwise utilitarian crossover SUVs, but with varying degrees of success. With the 2014 Infiniti QX50, it's almost the opposite scenario. See, the QX50 is a true athlete, and it's one of the most entertaining vehicles to drive in the compact luxury crossover class. The question, more likely, will be whether it's practical enough for you.

Formerly known as the Infiniti EX, the Infiniti QX50 is still Infiniti's smallest and least expensive crossover SUV. It's based on the old G37 sport sedan (not the new-generation Q50 sedan). Accordingly, it inherits the G's strong 3.7-liter V6 engine, responsive steering and athletic handling. The luxury aspect is nicely covered as well, as the posh interior combines a stylish yet functional design with high-quality materials and plenty of standard and optional features.

Our main concern relates to the "utility" aspect of this SUV, as the QX50's backseat is short enough on legroom that most adults won't want to be stuck there for anything longer than a quick trip. Cargo space is similarly limited compared with its luxury crossover competitors.

The 2014 Infiniti QX50 is a five-passenger luxury crossover SUV that's offered in two trim levels: base and Journey. Both are available in either front- or all-wheel drive.

Standard equipment on the entry-level QX50 includes 18-inch alloy wheels, automatic headlights, foglights, power-folding heated mirrors, keyless ignition/entry, dual-zone automatic climate control, leather upholstery, power front seats (eight-way driver, four-way passenger), heated front seats (all-wheel-drive models only), 60/40-split-folding rear seats, cruise control, a tilt-and-telescoping steering wheel, trip computer, a 7-inch display, a rearview camera and a six-speaker sound system with a CD player, satellite radio, an auxiliary audio input jack and an iPod/USB audio interface.

Stepping up to the Journey model gets you a sunroof, heated front seats (includes rear-wheel-drive models), wood interior trim, a power-adjustable steering wheel and Bluetooth phone connectivity.

The Journey model also offers a number of desirable options, including a Premium package that bundles a 360-degree parking camera system, front and rear parking sensors, an air purifier, Bluetooth audio connectivity, a navigation system, voice controls and an 11-speaker Bose audio system.
