A select group of young international designers will submit innovative mock-ups of what an eco-friendly popemobile should look like.

For the first time, the annual Autostyle Design Competition will have a special category for a popemobile, according to L'Osservatore Romano.

The vehicle design must meet standards for low-emissions, as well as the Vatican's safety and security standards, it said.

A commission will choose 12 student finalists who will then have seven to eight months to create a new popemobile design, said Sara Ferraccioli of Berman, the Italian car-parts manufacturer sponsoring the competition.
