Oldsmobile 442 (1973-74)
The new design, a colonnade-style coupe, and rising emissions and safety standards all affected the 442 lineup, which returned as an option on the midsize Olds lineup. The muscle car era was gone, but Olds fought back as one of the last really powerful muscle cars. The 455 was still available, but only with 300 HP in the expensive W30 package, which included the 4-speed manual transmission.
