Here are some leaked low-res images of the 2011 Infiniti QX56, which will make its debut at the New York Auto Show. The largest of Infiniti’s 4X4s is meant to be a rival to the Lexus LX, and is based on Nissan’s new Patrol that was unveiled in the Middle East last month.

The latest Patrol is powered by a 5.6-litre direct-injected V8 with 400 bhp and 550 Nm paired to a seven-speed automatic transmission, and it’s most likely that the QX56 will sport the same drivetrain. The Infiniti should also come with the Patrol’s Hydraulic Body Motion Control System, All Mode 4X4 system with four selectable presets, Hill Start Assist and Hill Descent Control. While the Patrol name conjures up images of UN peacekeeping forces in hostile terrain, the latest version is positioned upmarket – kit includes a new multi-screen DVD entertainment system and “curtain vents”.

Here, the designers fused Infiniti-style headlights, rear lights and the wavy rear window line into a big, boxy SUV. And while all these cues work well on the marque’s smaller “coupe style” crossovers, we think that this is one of the most awkward looking 4X4s on sale. The current QX isn’t pretty, but at least it looks consistent.

More images after the jump.
