No matter how aerodynamic or streamlined the Outside Rear View Mirrors are, they do end up creating a lot of wind noise. One solution is to make them as much narrow as possible, but then, that size wont be of any use.
The solution for that second problem is to replace the mirrors with cameras. Besides reducing the drag, they do offer few more advantages over the conventional mirrors. They offer much better field of view, improved visibility at night and in inclement weather, to name a few.
Lexus’ version of that technology is called Digital Side-View Monitors. They transmit the images onto 5-inch displays located at the base of the A-pillars. The cameras are shaped in such a way that they resist the accumulation of raindrops and snow, leaving the driver’s view unaffected.
The system automatically enhances the corresponding area―left, right or behind―when the turn signals are activated, or when the transmission is put into reverse. The views can be manually enhanced as well.
Lexus claims to be the first manufacturer in the world to offer the technology on a mass-produced vehicle. The Digital Side-View Monitors will make their debut on the new ES in late October. At this time, it’ll be available only in Japan.
