Why it matters

The 1930 SSK "Count Trossi" Roadster is a roadster-bodied SSK that won Best of Show at the Pebble Beach Concours d'Elegance in 1993. The SSK on which it is based was the short-wheelbase development of the Mercedes-Benz S-series supercharged sports car, and the factory records only 33 SSKs and SSKLs in total.

History

The Pebble Beach list of past winners records the car as the 1930 Mercedes-Benz SSK Count Trossi Roadster, Best of Show in 1993. No cached page gives the history, coachbuilder or chassis number of this particular car.

The archive describes the SSK (design name W 06 II, 1928-1932) as a shortened Type S chassis, with a 2950 mm wheelbase against 3400 mm for the S and SS, a 7065 cc supercharged six-cylinder M 06 engine and a four-speed gearbox. The Mercedes-Benz media article says the SSK was developed in 1928 for hillclimbs and was technically largely identical to the SS.
