It's getting harder and harder to justify driving a large crossover or SUV without hybrid propulsion to make it (at least seem) a little greener. So at the upcoming New York Auto Show, Infiniti will present a hybrid version of its big QX60. Now if you're scratching your head thinking which the QX60 is in Infiniti's newly-renamed model line, you may recognize it better as the JX35, a seven-seat crossover which Nissan's luxury brand unveiled in August 2011 at Pebble Beach.

As part of the brand's new naming scheme, it's been rechristened as the QX60. While the conventionally-powered version uses Nissan's ubiquitous 3.5-liter V6, the new hybrid version will pair a 2.5-liter supercharged inline-four with a 15-kilowatt electric motor. The hybrid powertrain is different from that used in Infiniti's other hybrid, the M35h, and will be available in both front- and all-wheel drive versions at an approximate $3,000 premium. Because the lithium-ion battery is housed beneath the third row of seating, the hybrid crossover won't lose any actual space to the conventionally-powered version.
