For the 2014 model year, all INFINITI models will receive new names based upon "Q" for sedans, coupes and convertibles, and "QX" for crossovers and SUV's. The double-digit number represents the hierarchy in the INFINITI line. The first to receive the new badging will be the INFINITI Q50, an all-new luxury sports sedan that will made its global debut at the North American International Auto Show on January 14.
