1966 Oldsmobile Cutlass Apparel and Accessories by Legend Lines
The 1966 models were slightly restyled again, with body lines similar to the full-sized 88, and semi-fastback rooflines with extended sail panels and tunneled rear windows on Sport (pillared) and Holiday (hardtop) coupes. The Buick V6 was replaced on base models by an Oldsmobile-badged "Action-Line 6" version of Chevrolet's 250 cu in (4.1 L) "Turbo-Thrift" straight-6 engine, while the 330 cu in (5.4 L) Jetfire Rocket V8 continued with power ratings of 250 and 320 horsepower (190 and 240 kW). New that year was the Cutlass Supreme four-door hardtop sedan also dubbed the Holiday Sedan by Oldsmobile, the first such body style for Olds' intermediate line. The Cutlass versions came with full carpeting and featured Strato bucket seats of a new design with higher and thinner seat backs, or a no-cost bench seat option. Head rests were an option.
