Why it matters

The 1106 Sport Coupe was Packard's most streamlined Twelve, a LeBaron fastback on a shortened chassis inspired by Mercedes-Benz's Autobahn-Kurier. Only four were built and all four are known, making it one of the rarest Packard production bodies.

History

Packard created the 1106 by mounting Twelve running gear on a shortened, Standard Eight-based frame and had LeBaron of Detroit build de Sakhnoffsky-designed fastback coupés. The 445.5 cu in V12 gave 160 bhp through a three-speed synchromesh gearbox with vacuum-assisted clutch. One car served as the 1934 New York Auto Show exhibit and was later updated by Packard with Twelfth Series front sheet metal.
