For 1963, the full-size Bel Air received a new facelift and the overall length increased to 210.4 in. The 235.5ci I-6 was replaced with a 230ci six-cylinder as standard equipment and increased output to 140 hp.
For 1962, new sheet metal except the door panels was changed contributing to what most collectors believe to be one of the cleanest and important Chevys of yester-year.
The 1961 Bel Air ushered in yet another generation and was all new. It offered new slimmer, cleaner lines without the excessive fins promising to be easier to park, garage, etc.
The 1959 Bel Air was all new, and Chevy spared no expense at making it look like nothing else on the road. This restyle initiated the fourth-generation Bel Airs.
The 1958 Bel Air sported "curves where before there were lines." New to the Bel Air line was the well-appointed Impala models available as either a 2-door hardtop coupe or 2-door convertible.
For 1954, the Bel Air stayed essentially the same, except for a revised grille and taillight, and a revised engine that had insert bearings and higher oil pressure. The revised engine saw a slight performance increase.
The 1953 Bel Air became its own line sporting several new models. It featured Fisher unisteel construction, high-compression engines, and new rear axle.
Relatively unchanged from the previous year, the 1951 Bel Air saw increased production numbers as America took grasp of it's handsome looks and plush interior.
