While there’s no denying that the mid-engine, supercar-like design of the Corvette C8 is very attractive and eye-catching, the configuration creates a huge blind spot with poor-to-no visibility when changing lanes. For that reason, GM Authority believes that the GM Side Blind Zone Alert feature is an absolute necessity on the Corvette C8, something that should be seriously considered by those interested in buying Chevy’s new mid-engine sports car, whether in Coupe or Convertible form.
Side Blind Zone Alert (SBZA) is a GM active safety technology that provides side mirror alerts to help the driver avoid crashing into a vehicle in their side blind spot (or zone) during a lane change maneuver.
The technology uses one left and one right short-range radar located in the rear corners of the vehicle to monitor moving vehicles up to 11 feet (3.5 meters) behind the side mirror, one lane over from both sides of the vehicle. The system only works when the vehicle is in a Forward gear.
A driver is warned of a moving vehicle in the side blind zone via an amber Lane Change Alert icon in the top outer portion of the side mirror. The icon illuminates in a steady way if the system detects a vehicle in the Corvette’s blind zone, and flashes if the driver activates the turn signal in the direction of the detected vehicle. As such, an illuminated Lane Change Alert icon indicates that it’s unsafe to change lanes. While Side Blind Zone Alert is intended to assist in changing lanes, the driver is still responsible for checking mirrors, looking over the shoulder, and using turn signals before making a lane change.
It’s worth noting that Side Blind Zone Alert does not deliver a Safety Alert Seat vibration or any form of beeping alerts. Additionally, one can turn the system on or off via a setting in the vehicle settings menu.
On the 2020, 2021 and 2022 Corvette, Side Blind Zone Alert is standard on 2LT and 3LT but not available on 1LT models. Potential customers should take that into consideration when buying a new or used C8.
Side Blind Zone Alert is part of a set of modern active safety features GM introduced with the C8 Corvette, something completely missing from the C7 Corvette. Besides Side Blind Zone Alert, the safety suite includes Rear Cross Traffic Alert, HD Rear Vision Camera, Front Curb View Camera, Rear Camera Mirror, and Rear Park Assist. All these add up to underscore the C8 Corvette’s role as a “true supercar for every day.”
