Cadillac may be set to follow in the footsteps of Genesis in revitalizing the popularity of luxurious four-seat convertibles. Nearly two years after Genesis introduced its striking X Convertible concept in 2022, Cadillac has unveiled its own electric convertible concept reminiscent of classic luxury models, called the Sollei. The future of this model, however, hinges entirely on whether GM allows Cadillac to bring it to life.
The Sollei builds upon the foundation established by the Celestiq. Utilizing the same Ultium chassis and adopting a similar front design, it distinguishes itself from the four-door Celestiq, which serves as Cadillac’s electric competitor to Rolls-Royce. Instead, Sollei is a nod to Cadillac’s heritage, echoing the plushness of vintage convertibles like the DeVille and Eldorado. The vehicle’s hand-painted “Manilla Cream” finish hails from the late 1950s Cadillacs. Regrettably, the Sollei is still in concept form; GM has only labeled it an “imaginative design exercise.”
In contrast to many contemporary luxury convertibles—such as the Mercedes SL-Class, BMW 8 Series, Maserati GranCabrio, and Aston Martin DB12 Volante—the Cadillac Sollei purposefully avoids sporty connotations. Its name, derived from “Sol” meaning “sun” and “Lei” meaning “leisure,” aptly reflects a design focused on relaxation, featuring a high shoulder line, a gently sloping rear, and smooth contours.
This sense of leisure extends into the interior, where the Sollei incorporates design elements reminiscent of lemon meringue pie. Beyond its visual appeal, the cabin is environmentally conscious, using Mycelium™ materials crafted from mushrooms and untreated open-pore wood. Amenities such as a rear-seat drink cooler, crystal glassware, and intricately designed sunburst metalwork align with the overall relaxed ambiance. Additionally, the vehicle comes with a bird-watching kit—complete with 3D-printed acrylic bird calls, a leather-bound journal, and a leather tool roll—all housed in a luxurious leather-wrapped case. It’s a unique touch that embodies a laid-back lifestyle.
The Sollei symbolizes a nostalgic return to luxury convertibles, showcasing GM’s most advanced electric vehicle technology. Its unveiling, alongside Genesis’ rumored X Convertible, could herald a revival of classic luxury convertibles. However, GM must have the confidence to permit Cadillac to manufacture the model. With the Celestiq’s foundation and design, putting the Sollei into production appears to be a feasible venture for GM. Even as an ultra-low-volume halo model meant to inspire potential Cadillac customers, the Sollei could help revive a cherished era of luxury in America. If enthusiasts rally behind it, we might just encourage Cadillac to reintroduce beloved convertibles infused with modern technology.
