- Cadillac has revealed a potential flagship electric convertible in concept form
- The Sollei concept features a 2+2 seating arrangement in a leather and wood-lined cabin
- The “Sun” in the name Sollei refers to the sun
Cadillac showed what a modern convertible from the brand could look like with the model’s reveal on Monday. Sollei Concept.
Revealed in Cadillac House in Vanderbiltwhich is part of General Motors’ extensive Global Technical Center in Warren, Michigan, and is where the Similar style Celestiq is built, the electric convertible is described by Cadillac as the brand’s “vision” of offering a convertible with a modern design.
Cadillac didn’t say what underpins the Sollei, but it’s likely GM’s Ultium battery and technology suite, which underpins all current Cadillac EVs, including the Celestiq. In addition to styling and potentially platform, the concept also borrows from Cadillac’s current EV lineup with its 55-inch curved display that spans the dashboard, a feature that debuted on the Celestiq and also appears on the 2025 Escalade IQ and Updated 2025 Escalade.
Forming the rest of the cabin is 2+2 seatsas well as leather trim that matches the exterior color, in this case a shade known as “Manila Cream.” Cadillac used it on vehicles in the late 1950s. And the wood panels used on the seatbacks are meant to represent the sun’s rays. The “Sun” in Sollei is also a reference to the sun.
Cadillac is also using the Sollei concept to demonstrate how sustainable materials can be introduced into the brand’s lineup. One of them is a leather-like material made from mycelium, which is the underground structure of mushrooms and other fungi. It is used for a cell phone charging dock and in some other areas of the dashboard.
On the outside, the Sollei concept matches the Celestiq’s design front and rear. The concept also appears to have a relatively short dashboard-to-axle ratio, resulting in an almost squat look to the front third of the vehicle when viewed from the side.
Cadillac has revealed convertible concepts in the not-so-distant past, though they never went into production. What’s different this time around is the specialized production line Cadillac has established for the Celestiq. It features equipment designed for low-volume production, such as 3D printers, and could be used to produce Solleis alongside the Celestiq.
The Sollei isn’t the only concept expected from Cadillac this year. The brand also plans to showcase its performance plans for the electric vehicle era with the Opulent speed conceptwhose teaser was shown in March.
