The end result was essentially the most potent manufacturing Cadillac ever, proof that the division was dead critical about cracking the enthusiast market. Extra proof got here with a necessary six-pace handbook transmission, the identical Tremec T56 unit used within the ‘Vette, however relocated from the rear to only behind the engine. Cadillac hardly missed a trick, specifying a heavier-than-inventory driveshaft, a restricted-slip rear differential with strong but mild forged-aluminum housing, and fairly tight gearing (3.73:1).

For one factor, the new DeVille not solely looked trimmer, it was, giving up two inches in width and size but adding 1.5 inches in wheelbase (to 115.3), which benefited inside room and comfort. Then too, prices were surprisingly little changed for the three fashions. D’Elegance was retitled DHS (for “DeVille Excessive-luxurious Sedan”), whereas Concours grew to become the DTS (“DeVille Touring Sedan”). Every began at $44,700, the bottom DeVille at $39,500.

Additionally shared was the ever-spectacular Northstar V-8, tuned for 300 horsepower within the DTS, 275 for other fashions.

Then, too, it was comparatively expensive ($2600-$2700). Had anyone else built it, the Nomad probably would have seen minuscule production, but a respectable 8386 were constructed for 1955, 7886 for ’56, and 6103 for 1957.
