For the longest time, Ford has been America's favorite purveyor of pony cars. The Ford Mustang has always been a beloved product, but Dodge has been consistently eating away at the Blue Oval's piece of the pie, and that has finally culminated in Dodge being crowned the king.

Both automakers have revealed their sales figures for 2021, and for the first time ever, Mopar has outsold the 'Stang with the Dodge Challenger. Stellantis says that Dodge sold 54,314 Challengers last year, a 3% increase over 2020's final figures of 52,995. At Ford, the Mustang shifted 52,414 units, a substantial drop of 14.2% from the 61,090 Mustangs sold in 2020.

If you add the electric Mustang Mach-E to the figures, Ford fans find the figures easier to swallow. Combined, the electric crossover and the traditional Mustang have sold 79,554 vehicles, a 30.2% increase over Mustang sales totals for 2020. Still, things could be worse.

General Motors has struggled to get the Chevrolet Camaro to achieve the same popularity as its Detroit rivals, and that trend is continuing with just 21,893 examples sold last year, a massive 25% decline compared to 2020's total of 29,775 units. The Camaro is in desperate need of a rethink if Chevrolet is to make any inroads into the segment before everything goes electric.

Interestingly, not all older cars are being shunned by buyers at US dealers. The Dodge Viper was killed off in August 2017, yet some new models still reside on lots. Four were sold in 2020 and another four found their first owners last year too. We've seen the impressive feats that this car is capable of, but it's unlikely that we'll see the name revived anytime soon unless as a future EV.

The Viper joins a list of unusual sales in 2021 that includes the Dodge Dart (10 were sold, up 43% from 2020), the Chrysler 200 (15 units were sold for a 67% increase over 2020 figures), the Chrysler Town & Country (four were sold in 2021), and even the Jeep Patriot, which saw sales increase by a staggering 433% to 16 units.
