Cadillac's completely restyled 1957 offerings borrowed heavily from the
lines of the Park Avenue, a hardtop sedan "idea" car shown at the 1954
Motorama. A new X-member chassis contributed to structural rigidity as
well as to a profile nearly three inches lower than before. Of course, the
lack of side rails meant that the new frame afforded virtually no lateral
impact protection, but Detroit wasn't particularly safety-conscious in those
Once more the Eldorado Biarritz and Seville had their own rear-end
configuration. The work of Ron Hill, a talented 23-year-old design
newcomer, it featured a sloped deck flanked by rounded fenders sprouting
sharply pointed fins. Rear wheel openings were again skinless, and the
lower rear fenders were liberally garnished with chrome. The hood
ornament was eliminated, contributing to a smoother frontal appearance.
Overall, the '57 was more readily distinguishable from other Cadillacs than
any Eldorado since the original. Oddly enough, the dual four-barrel
carburetion was dropped this year, and standard horsepower backed off
slightly to 300 despite an increase in compression ratio. The all-out
performance buff could still get the twin pots and 325 horses, but they now
But the Biarritz and the Seville were no more than a warm-up for 1957s
main event. As it had in the Thirties, Cadillac plunged into the
super-luxury market with the new Eldorado Brougham, a virtually
hand-built hardtop sedan on a more compact 126-inch wheelbase.
Conceived largely in response to the Continental Mark II from Ford Motor
Company, it came with every extra in the Cadillac accessory book -- plus a
few brand-new exclusives -- but was no more successful. Price was a
formidable $13,074, for which you could very nearly buy both a Biarritz
and a Seville. Demand was predictably limited, and just 400 were
built for the model year, all in Cadillac's own plant, by the way.

SERIES 70 ELDORADO
Announced in December, 1956 and released around March, 1957, the Eldorado Brougham was a hand-built,
limited-edition four-door hardtop sedan derived from the Park Avenue and Orleans show cars of 1953-1954.
Designed by Ed Glowacke, the Brougham featured America's first completely pillariess four-door body styling.
The ventipanes were electrically controlled. The Brougham was further distinguished by a brushed stainless steel roof, the first
appearance of quad headlights and totally unique trim. The exterior ornamentation included wide, ribbed lower
rear quarter beauty panels (extending along the full rocker sills) and a rectangularly sculptured side body "cove"
highlighted with five horizontal windsplits on the rear doors. Tail styling treatments followed the Eldorado theme
and "suicide" type hanging was used for the rear doors. Standard equipment included all possible accessories
