The Dodge Super Bee made the move from the Coronet line to the Charger line for 1971 only, after which this model was discontinued. Several other models were carried over from 1970, including the 500, R/T, and SE. Sales of the R/T declined due in part to higher insurance costs. A total of 63 Hemi versions were built, and 2,659 were built with other engines that year. Increasing insurance rates, combined with higher gasoline prices, reduced sales of most muscle cars and 1971 was the last year of availability for the 426 Hemi "Elephant engine" in any car. The 1971 model year was also the last for the 440 Six-Pack engine, which could still be mated to a Hurst 4-speed transmission, as well as the automatic. In the Super Bee's final year, the 340 became a $44 option over the standard, low-compression 383 .
