The 1954 Bel Air by Chevrolet with its 125 horsepower Blue Flame 6 engine was cited by one automotive critic as the most dependable car produced since the Model A Ford. The engine featured hydraulic valve lifters and was coupled to a Powerglide transmission. It had a new Chevy medallion on the trunk, revamped tail lights and additional vertical bars on the grille. It sold for about $2,000. In 1954 Edward Arn was the governor of Kansas, the Kansas Turnpike was in the planning stages with a price tag of $160,000,000 million and Roger Bannister broke the four-minute mile barrier.
