Yes; 215 CI V8. Square bore tho; 3.25 x 3.25 vs. 3.5 x 2.8. Wiki states "An early-development supercharged version of the 215-cubic-inch (3.5 L) V8 was used in the 1951 Le Sabre" but I doubt that that's literally accurate; seems the only thing shared is the displacement.
Technically you are correct, but the design owes more to Buick, including the grille ornament, then any other GM brand.
I love early concept cars. The side profile on the LeSabre is just gorgeous. If they would've mellowed out the front and rear styling a bit to make it production ready, who knows? There might be one sitting in the garage.
And not just the design. Cliff Studaker, who literally "wrote the book" on the then new 400/430 engines, related to me personally that his first job for Buick, in 1950, was as the dyno testing operator for the XP 300 engine program.. He gave me a whole sheaf of literature on it. That engine was also installed in the Le Sabre concept, as well as a rear mounted dynaflow trans, So while the concept car did not wear a Buick badge, it had the heart of one. JW
Right, but technically & chronologically; it’s Buick that has the heart (and the grille badge) of the GM LeSabre. Buick got the red, white, blue circular emblem & a V8 in ‘53, as we all know. Not trying to be argumentative, just a stickler for concept car / GM history. GM was excellent at stylistic recycling; LeSabre’s angled / Dagmar front bumper went to Cadillac, the fins; ‘57 Cad, mini tails (4) were on the ‘54 Buick, everyone got the wrap windshield, GM toyed with central headlight during the ‘59 Olds & Chev program, Buick picked up the rear quarter character swoop, etc.
