The car pictured has a 71 grill, but the T/A was only available in 70. Funny how the text above the photo says the same, but they caption the photo a '71 T/A
1971.
In 1971, designers made subtle styling changes to the Dodge Challenger, providing new treatments to the taillamps and grille. The single-taillamp design from 1970 became two distinct lights for 1971, and a new-for-1971 twin-inlet Challenger grille was painted silver on standard models and black on R/Ts.
Challenger R/T models also received a set of fiberglass quarter-panel louvers. An additional coupe model with fixed quarter windows was added to the lineup.
As in 1970, a wide range of trim levels, exterior colors and striping options made the Dodge Challenger easy for customers to create a special car. However, for 1971, Dodge dropped the T/A (it was no longer racing in Trans-Am), SE models and R/T convertible.
New EPA emission standards led to some powertrain changes; the optional 375 horsepower 440-cubic-inch was eliminated, as was the Six Pack-equipped 340-cubic-inch powerplant. The 383-cubic-inch Magnum engine was detuned to 300 horsepower by lowering the compression ratio for improved emissions. However, a 390 horsepower six-pack 440 V-8 was available, and the 425 horsepower 426-cubic-inch HEMI still topped the vast engine offerings.
A Dodge Challenger paced the Indianapolis 500 race in 1971. Dodge produced 50 Challenger convertible pace car replicas — all painted HEMI Orange with white tops and interiors.
