It's been since the late 1940s that the Cadillac Motor Division of General Motors has attempted to market a fastback design.
Ford Motor Company's Lincoln Division had also tried with a fastback version Cosmopolitan, which bombed in the market, and was rushed out of production about as fast as Chrysler's 1934 Airflow ( which Stellantis is going to bringing back, if only in name ). Journalists had attached the 'beached-whale' sobriquet to the Cosmo.
At Cd 0.25, the Celestiq isn't transformative, but even GM understands tradeoffs between styling, battery range, and performance ( their Impact/ EV1 land speed record car of 1993 was Cd 0.137, and the 1987 Sunraycer, with the full wheel fairing package was reported by Cal Tech as Cd 0.089 ).
It will be interesting to see if the market, now paying for aero Rolls-Royce and aero Bentley, will drop $300,000+ for the aero Caddy.
