Cadillac Sollei concept EV tributes 1950s land yachts

The company calls it the "ultimate expression of a coachbuilt luxury electric convertible,” designed to push the boundaries of the company clientele's future commissions. The big convertible follows in the wake of the new handbuilt Cadillac Celestiq limo, a car that captures the flowing lines and never-ending dimensions of a 1950s American saloon. 

Getting its name from 'sun' (sol) and 'leisure' (lei), the Sollei is supposed to reimagine the discovery of travel, delivering a personalised driving experience that connects its occupants with the world around them. The car's substantial size and unfussy design have echoes of Rolls Royce, as do the vast doors that offer unrivalled backseat access and favour buttons rather than handles to avoid upsetting the car's smooth-bore finish. The look is completed with the Manila Cream paint that featured on Grandpa's 1950s Caddy. 

The interior offers similar levels of Rolls luxury with some stars and stripes excess thrown in for good measure. The cabin has a 55-inch infotainment screen that stretches between the car's milled aluminium windscreen pillars and is awash with unstained wood – hand-cut and laid using marquetry techniques, that gives an antique-furniture finish. The wood is joined by a new MycoWorks bio-based material grown in the lab using mushroom roots. Trippy. 

Zoned ambient lighting with 126 colour options handles the interior illumination and is meant to imitate sunbursts, as are the embroidered patterns on the seats. The pink Nappa-leather interior is supposed to mimic sunrise, and you get an aurora tint on the interior metalwork. 

Back seat passengers get a drinks cooler with crystal glasses hidden by an electrically operated glass panel. While the fridge is classic posh-car fare, the Cadillac's bird-watching paraphernalia is, as far as we're aware, unique. In a custom brushed metal and leather-wrapped case, you'll find 3D printed acrylic bird calls, a leatherbound journal with hand-painted illustrations, and a leather tool roll for pens and pencils.

Cadillac hasn't confirmed if the Sollei will be built or how it will be powered, but a production model would likely use the same underpinnings as the Celestiq, which has a motor at each end producing around 600PS (441kW) combined for 0-62mph in well under four seconds. Comfort will be the primary concern, though, and you can expect the convertible to be fitted with air suspension that's creamier than an In-N-Out Burger milkshake with a squirt of cream on top. 

If it does make production, expect the Sollei to cost well over £300,000.
