Dodge Challenger 1971 R/T 426 Hemi

Just 71 out of 27,377 Dodge Challengers built for 1971 left the factory with a 426 Hemi under the hood – and this dual-quad R/T is one of them. It also happens to be the last model year Dodge ever installed the legendary engine, making this car the literal end of the line.

A very cool ’71 R/T with a dual quad 426 Hemi!!

Out of 27,377 Dodge Challengers built for the 1971 model year, almost none of them left the factory with the engine most collectors actually want. This particular R/T isn’t just running that engine — it’s running the dual-quad version, which narrows the field even further. Add in the fact that 1971 marked the final year Dodge would ever offer this engine at all, and a car like this stops being just “a cool old Challenger” and starts being something closer to the end of an era caught on camera.

The Rarest Number in Mopar History

Just 71 Challengers were built with the 426 Hemi in 1971, out of 27,377 total Challengers produced that year — a rarity rate under three-tenths of one percent. Factory-rated at 425 horsepower at 5,000 rpm and 490 lb-ft of torque at 4,000 rpm, the Hemi came standard with the Air Grabber hood scoop, and period testing put a Hemi Challenger at roughly 5.2 seconds to 60 mph and 13.7 seconds through the quarter mile.

The Last Hurrah of the Street Hemi

1971 wasn’t just a slow sales year for the Hemi — it was the last year Dodge offered the 426 in any of its street cars, closing out one of the most famous engine programs in American performance history. Tightening emissions regulations, rising insurance premiums on high-horsepower cars, and shifting buyer tastes all converged at once, and Dodge simply stopped building it after that model year. That is exactly why a dual-quad ‘71 R/T like this one carries so much weight with Mopar collectors: it isn’t just rare, it’s the final chapter.
