Cadillac to Debut Video Rearview Mirror

Cadillac's mirror can switch to unobstructed video mode (top).

General Motors Co.'s Cadillac unit will introduce a video screen to replace the traditional rearview mirror in its 2016 CTS midsize sedan.

Cadillac says the video-based system provides four times the rearward field of vision of a conventional inside rearview mirror.

The display consists of a 1280 240-pixel LCD display built into the usual mirror housing. The display uses a rear-facing high-definition camera mounted outside the car. The camera's position allows it to stream video unobstructed by the rear roof pillars, rear seats or objects blocking the rear window.

Cadillac notes that the system's video reduces glare, yet allows a crisper image in low-light situations. The new display also can be toggled to function as a conventional electrochromic mirror.

The Cadillac system will debut about the same time Nissan Motor Co. is expected to introduce its own rearview LCD display in global markets. Nissan unveiled its technology, which offers the same features, at the Geneva auto show in February.
