Why it matters

The Challenger T/A was built to homologate the Challenger for the SCCA Trans Am series, in the same way as the AAR 'Cuda. RM Sotheby's calls it uncommon, and cites 2,399 examples built. It was powered by a 340 cu in Six Pack V-8.

02Production & history

Production

Every figure says what it counts.

What is countedFigureBasisStatus
Total model productionChallenger T/As produced (989 with A833 4-speed) 2,3991,2 Factory production Disputed
Why more than one figure?

Sources differ: RM Sotheby's and Mecum catalogues say 2,399 built (989 with A833 4-speed); Supercars.net gives 2,539 in its data table.

Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.

History

The T/A was built to homologate the Challenger for SCCA Trans Am racing, as the AAR 'Cuda was for Plymouth. A documented car in the T/A Registry was offered by RM Sotheby's in 2014 with a Galen Govier documentation, two build sheets and its original 340 cu in Six Pack V-8.

06Reference

Identification guide

How to tell an original from a replica or later conversion.

Features listed by the auction house for a genuine car are T/A striping and graphics, a black fiberglass Sport hood with tie-down pins, front and rear spoilers, chromed megaphone side-exit exhaust, quick-ratio steering, power front disc brakes, heavy-duty suspension and staggered-size Rallye wheels. The same lot cites build sheets, T/A Registry listing and Galen Govier documentation as proof. A second 2014 lot was sold as a tribute rather than a documented car.
