Buick Riviera 1972

The 1972 Riviera continued to sport the "boat-tail" design, but the vents on the trunk lid were eliminated. GM decreed that its engines had to be rated in net SAE output, a more realistic measure of engine power, and the Riviera's 455 power rating dropped to 250 bhp for the base model and 260 bhp for the GS. Top speed fell to 112 mph.

Production: 33,728
Engines: 455 V8 250 bhp. (GS) 455 V8 260 bhp @ 4400 rpm, 380 lb-ft @ 2800 rpm.
Performance: N/A
