Gliding with the “Blue Lady”
As announced in December 1956 and available by March 1957, the Cadillac Series 70 Eldorado Brougham was designed by Ed Glowacke, who was part of Harley Earl’s design studio at General Motors. Arguably the most beautiful and most sought-after Cadillac ever built, the Eldorado Brougham was Cadillac’s response to Ford Motor Company’s Continental Mark II. The prototype Brougham was a hand-built, true pillarless four-door hardtop that first debuted as a featured show car in the GM Motorama for 1955. Derived from the ultra-luxurious Park Avenue and Orleans show cars of 1953-’54, the Brougham was stunning with its brushed-stainless-steel roof. Other exterior ornamentation included polished-stainless-steel lower rear-quarter panels with full rocker sills and rectangular-shaped side body coves cut into the front and rear doors, with horizontal wind-splits set into each cove. The pillarless four-door design had the rear doors opening toward the rear of the car (“suicide” style), allowing easy access for back-seat occupants. With all four doors open you could barely see the stub B-pillar.
The Brougham was the first to offer quad headlamps that, at the time, were still illegal in some states. The air suspension also proved unreliable, and Cadillac later released a kit to convert cars to rear coil-sprung suspension. Broughams still using the factory air suspension are rarer and thus more valuable today.
At 5,315 pounds, the Eldorado Brougham was a brute and required Cadillac’s largest and most powerful overhead-valve V-8 engine. The 365-cu.in. V-8, fed via dual Carter four-barrel carburetors and backed by Cadillac’s Hydra-Matic four-speed automatic transmission, produced 325 hp at 4,800 rpm and 400 lb-ft of torque at 3,200 rpm
