Nearly 35 years after its arrival, the luxury sedan that launched Lexus in America still commands attention. That's no small feat given the endless permutations of today's SUVs, but the 2023 Lexus LS 500, like its predecessors, remains the automaker's canvas for tech, comfort and safety innovations. The LS 500 carries over largely unchanged for 2023 with one notable exception: A revised infotainment system adds a new touchscreen (still sized at 12.3 inches) and finally dispenses with the clumsy touchpad control of earlier systems. Features are now accessed through the touchscreen or voice commands. The updated system adds a voice assistant, de rigueur among modern luxury cars, that can respond to natural speech and control media, navigation.
