Why it matters
The 1970 R/T convertible was the sportiest open version of Dodge's new E-body pony car, and the Hemi and Six Pak engine options made it the performance flagship. The R/T convertible was dropped after 1970, so only one model year of the body-and-trim combination exists.

History
The Challenger was planned from late 1966 under Dodge styling chief Bill Brownlie and arrived for 1970 on the new unitised E-body shared with the third-generation Barracuda. It was offered as hardtop and convertible in standard and R/T forms. The R/T carried a 335 hp 383 Magnum V8, heavy-duty Rallye suspension and brakes and a Rallye instrument cluster with an 8,000 rpm tachometer, with 440 Magnum (375 hp), 440 Six Pak (390 hp) and 426 Hemi (425 hp) engines as options.
Production of the 1970 R/T convertible is listed at 1,070 cars. For 1971 the R/T convertible was dropped.
