Nearly two years after Korean premium car manufacturer Genesis rolled out the stunning X Convertible concept in 2022, which was an electric vehicle that traces its origins back to the Genesis X Concept and is linked to the X Speedium Coupé, sharing the same platform with both concept cars.

America’s luxury brand has its own electric convertible concept that reminds us of classic two-plus-two luxury drop-tops, which is this Cadillac Sollei.

Will General Motors (GM) ever let Cadillac build this car? The Sollei continues where the Cadillac Celestiq left off. It uses the same Ultium chassis as the Celestiq and even wears the same front end.

However, while the four-door Celestiq is Cadillac’s electric answer to a Rolls-Royce rival, the Sollei is a throwback to the brand’s squishy, old-school luxury convertibles, like the DeVille and Eldorado.

Even its hand-painted “Manilla Cream” color was originally used on late-’50s Cadillac’s. Unfortunately, the Sollei isn’t slated for production yet, as GM’s only termed it an “imaginative design exercise.”

Unlike most modern luxury convertibles on sale today, the Cadillac Sollei doesn’t have any sporty pretensions. Its current possible rivals are the new Mercedes SL-Class, BMW 8 Series, Maserati GranCabrio and Aston Martin DB12 Volante,

Its very name. which is the combination of “Sol” and “Lei” it means “sun” and “leisure,” respectively. Fitting for a design with a high shoulder line, low-sloping rear end, and smooth bodywork, suggesting relaxation rather than blood-pumping excitement.

That same feeling of leisure seems to carry into the cabin, too, where its Celestiq-borrowed interior gets a color scheme seemingly inspired by lemon meringue pie.

Deliciousness isn’t its only attribute, though. With its Mycelium by MycoWorks materials (literally a material made from grown from mushrooms) and unstained open-pore wood trim, the cabin is eco-friendly, too.

The rear-seat drinks cooler, crystal glassware, and sunburst-effect metalwork keep with the chill, relaxed theme. There’s even a bird-watching kit, which includes 3D-printed acrylic bird calls, a leather-bound journal, and leather tool roll for pens, all found in a leather-wrapped case.

All this combines to make a throwback convertible luxury car, contrasted by GM’s most advanced EV technology. Combined with Genesis’ aforementioned X Convertible that’s long been rumoured for sale, this concept could mark the return of old-school luxury convertibles. However, GM needs to find the guts to give Cadillac the green light to build it
