Four Turbocharged Production Cars Existed In 1978, And Two Of Them Were Buicks

Key Points:

• Turbocharging technology, initially popular in the late 1970s and '80s for boosting performance, is now valued for improving engine efficiency and fuel economy compared to naturally aspirated engines.
• In 1978, Buick introduced turbocharged engines in the Regal Sport Coupe and LeSabre Sport Coupe, marking America's only turbocharged production automobile engines at the time, though Buick downplayed the "turbo" label in favor of "Sport."
• Buick's turbocharged 231-cubic-inch V6 engine delivered 150 or 175 horsepower and better fuel efficiency than their V8 counterparts, supported by upgraded suspension and handling features branded as "Rallye ride and handling."
• While Buick led the American market in turbocharged production cars in 1978, earlier American turbocharged models included the 1962 Oldsmobile F-85 Jetfire and the 1965 Chevrolet Corvair Corsa Turbo-Air 6, both pioneering but short-lived efforts.
• Buick's turbocharged models represent an important phase in American automotive innovation, helping to popularize turbo technology as it gained broader acceptance and use in the industry.
