Somewhere in the snowcapped mountains, a gray flag reading "Be Ready to Winter" waves in the wind. A 2015 Infiniti QX60 glides by in slow motion to the overture of Mozart's "The Magic Flute." Inside, a family eats popcorn with smiles on their faces. A man in an Infiniti Q70 drives down a ski slope, weaving through the flags, while a woman reverses her Infiniti QX50 through a cone-marked path. Soon, the cars come together against a backdrop of snow and clouds.
