Infiniti’s QX56 fullsize SUV is seriously starting to show its age against updated rivals in the luxury SUV segment. Mercedes Benz has just taken the wraps off its 2010 GL-Class facelift, and excitement surrounding BMW’s X5 and X6 SUVs is still going strong, especially with the reveal of the new M performance versions.

Despite the tough odds, Infiniti hasn’t given up completely on its staid QX56 and has optioned up the SUV for another year of sales. Pricing for the 2010 Infiniti QX56 will start at $56,050 for the 2WD model and top out at $59,150 for the QX56 4WD. Both are equipped with a standard 320hp (277kW) and 393lb-ft (532Nm) of torque 5.6L V8 engine, 5-speed automatic transmission, leather trim and a long list of luxury and technology features. Other features include xenon headlights, LED detailing, 20in wheels, a power sliding moonroof and power-operated rear liftgate.

Inside, the QX56 still offers seating for eight (with the optional 2nd row split bench seat), as well as a hard-disc navigation system, a 12-speaker Bose stereo and XM Satellite Radio and NavTraffic as standard.

Optional features include a Technology Package with adaptive cruise control, parking sensors, an entertainment system with a DVD player and 8in screen, and two wireless headphones and remote controller. A Tow Package, standard on the 4WD model, is also optional on the QX56 2WD, and maximum towing capacity is rated at up to 9,000 pounds.

Large SUVs and minivans have fallen on the hardest of times in the industry's late downturn, and casualties of the recession mount daily. One of these is the QX56, which will see its U.S. production ceased at the end of 2010. A successor is planned, however, and will enter production in Japan before arriving in U.S. showrooms by mid 2011.
