The Impala was once again Chevy's top-selling model in 1968, enticing 710,900 buyers that year. The model took on the Custom Coupe trim that had previously been used for the Caprice with some slight aesthetic changes. The tail lights reverted back to a more circular style, but were encased in horseshoe windows giving it a bit more serious look. This year maintained four different-sized engines and had the option between a two-speed Powerglide automatic trans or a three-speed Turbo Hydramatic.
