The 1955 Bel Air was very well received. "Motor Trend" magazine gave the Bel Air top marks for handling. "Popular Mechanics" reported acceleration for a V8 Bel Air with Powerglide as being 0- in 12.9 seconds, plus a comfortable ride and good visibility. On the other hand, the horn ring blocked some of the speedometer, regular gasoline made the engine knock and the first V8 engines off the line burned too much oil. Front legroom was 43.1". Brakes were 11" drums. A new option for V8-equipped 1955 models was air conditioning, with outlets on each side of the dashboard; a heavy-duty generator was included on cars equipped with this option; in 1955 and 1956, air conditioning could be installed on cars ordered with the standard three-speed manual transmission, overdrive or Powerglide, but from 1957 onward, an automatic transmission (or minus that, 4-speed manual transmission) was a pre-requisite option.
