For Infiniti, 2015 appears to be an opportunity for those running the auto brand to catch their breath after updating and renaming all of its models in 2014. To that point, models such as the QX50 and QX70 have been carried over unchanged, and the Q50 debuts with just a new Performance Wheel package. Positioned below the Q50 is the 2015 Q40, or what many consumers will recognize as a G37 sedan with different badges. There's a bit more activity with regard to the Q60 thanks to the introduction of a top-of-the-line Limited trim level. As for the QX60 crossover, it rolls into 2015 with an optional Wheat color interior and a retuned transmission. Relatively speaking, the big newsmakers are the Q70 sedan and QX80 SUV. Both have been mildly restyled and treated to additional safety features, but it's the Q70 that boasts a new extended-wheelbase version (aptly named Q70L) offering more than 5 in. of extra rear-seat legroom.
