Lexus kicked off the auto show with a “luxury flagship” crossover concept called the Lexus LF-1 Limitless. It sports a long hood and a muscular look with a coupe-like stance. Its signature spindle grille stays large, but takes on a new striking look that's complemented by thin LEDs. Cool treatments surrounded this new concept including hidden rear door handles, side cameras instead of mirrors, a 4D navigation system, and fully autonomous features that it calls “Chauffeur mode.” No specs were provided, but Lexus mentioned that it could be powered by various powertrains including hydrogen fuel cell, hybrid, plug-in hybrid, gas, or pure electric.
