QR Codes have been placed on the six prototype Chevrolet Spark EV all electric cars currently undergoing road testing in Southern California (image below). The QR Codes on the door panels resolve to a non-mobile page with updates on progress by Trista Schieffer, Lead Development Engineer. (Note to Chevy engineers: Mercedes put a QR Code on their new A-Class model while road testing earlier this year and built a dedicated mobile site). New rules in California require automakers selling traditional vehicles in the state to also sell an emissions free model. Hence the EV will be offered initially in California with no plans to sell nationwide.
