Chevrolet Bel Air
For 1961, Chevrolet again had a totally new body, not just new sheetmetal. Its wheelbase remained 119 in, but its length was now reduced slightly to 209.3 in. All engines options of the previous year remained in effect with the standard engines being the 235.5 CID Six of 135 hp or the 283 CID V8 of 170 hp. The V8 cost $110 more than the six and weighed 5lb less.
The Bel Air 2-door sedan used squared-off roof styling and large wrap-around rear window as opposed to the hardtop's swept-back design. The Bel Air 4-door Sport Hardtop still used a different roof line than did the 4-door sedan.
For 1962, all sheetmetal except the door panels was changed. Overall length was stretched slightly to 209.6 in. The 4-door Sport Hardtop was no longer offered in the Bel Air series. Standard engines remained the same as the previous year. A new 327 cu in V8 of 250 or 300 hp was offered in addition to the giant (for the time) 409 cu in V8 of 380 hp or 409 hp (305 kW) with the dual four-barrel carburetor setup. All wagons this year were 4-door models and separate distinctions for wagons were dropped. Now all models were either Biscayne, Bel Air or Impala series. Full carpeting returned as standard equipment on all 1962 Bel Air models for the first time in several years.
