Cadillac introduced the SOLLEI concept vehicle—a coach-built luxury electric convertible. SOLLEI conceptualizes an all-electric, 2+2 convertible.

SOLLEI is also Cadillac’s first concept vehicle to incorporate an innovative bio-based material developed in collaboration with MycoWorks. Used in the charging mats on the console and the door map pockets, Fine Mycelium by MycoWorks is ushering in a new era of luxury materials grown from mycelium (the renewable root structure of mushrooms). The material reflects Cadillac’s mission to pioneer renewable automotive resources.

A technology exclusive to MycoWorks, Fine Mycelium engineers mycelium cells as they grow to create three-dimensional structures that are densely entwined, and inherently strong. Fine Mycelium grows materials with superior strength, durability, and performance.

Grown in proprietary trays under precise conditions, each sheet has a unique code that allows MycoWorks to monitor and fine-tune the material, from inoculation to harvest. Fine Mycelium allows designers to fully customize desired specifications such as thickness, strength, texture and drape. Among other features.

The SOLLEI convertible exercise represents the brand’s vision to offer modern design this time in an open-air format, inspired by iconic Cadillacs from the past.

The concept was officially unveiled at Cadillac House at Vanderbilt, a newly restored, state-of-the-art facility at GM’s Global Technical Center campus in Warren, Michigan. This location is dedicated to providing a bespoke design experience for Cadillac CELESTIQ clients.
