Mercedes-Benz SSK
The Mercedes-Benz SSK (Super Sport Kurz, or Super Sport Short) is one of the most revered automobiles in history, a thundering supercharged sports car from the golden age of motor racing. Designed by Ferdinand Porsche during his tenure as chief engineer at Daimler-Benz, the SSK was a shortened, lightened version of the already fearsome SS (Super Sport) and represented the ultimate development of Mercedes-Benz's supercharged sports car lineage.
The SSK's engine was a colossal 7.1-liter (7,065cc) inline-six with a single overhead camshaft and a Roots-type supercharger that could be engaged by the driver by pressing the throttle to the floor. Without the supercharger, the engine produced approximately 170 hp -- already formidable for the era. With the supercharger engaged, output leaped to 300 hp, accompanied by a banshee shriek from the blower that became one of the most iconic sounds in motor racing. The supercharger was not intended for continuous use but rather for bursts of acceleration on straights and out of corners.
The chassis featured a ladder frame with solid axles front and rear, suspended on semi-elliptic leaf springs. By modern standards, the technology was crude, but the SSK's prodigious power and relatively light weight (for a car with a 7.1-liter engine) made it devastatingly fast. The four-speed manual gearbox transmitted power to the rear wheels, and stopping was accomplished by mechanical drum brakes on all four wheels.
The SSK's racing record was spectacular. Rudolf Caracciola, Mercedes-Benz's star driver, won the Mille Miglia in 1931 -- the first non-Italian to win the race -- driving a factory SSK. The car also triumphed at the Argentine Grand Prix, the Irish Grand Prix, and numerous hillclimb events across Europe. The SSK was virtually unbeatable in its class and often dominated races outright against cars with more modern engineering.
Only 33 SSK chassis were produced between 1928 and 1932, making it one of the rarest and most valuable automobiles in existence. Each car received bespoke coachwork, ranging from stark racing bodies to elegant touring coachwork. The most famous SSK of all is Count Carlo Felice Trossi's black SSK, which features a dramatic streamlined body with a flexing hood and exposed exhaust pipes. The Trossi SSK has been called one of the most beautiful automobiles ever created and is a permanent fixture in the Ralph Lauren car collection.
The SSK's design legacy extends far beyond its own production. Ferdinand Porsche's work on the supercharged Mercedes-Benz sports cars informed his subsequent career, including the Auto Union racing cars and ultimately the Volkswagen Beetle. The SSK represents the zenith of the Porsche era at Daimler-Benz.
Today, the SSK is among the most valuable automobiles in the world. When examples appear at auction -- which is exceptionally rare -- they command prices in the range of $7 million to $15 million or more, depending on provenance and coachwork. Several SSKs are in museum collections and will likely never be sold. The SSK is not merely a car; it is a monument to the heroic age of motor racing.
Acquiring a genuine SSK is an event of extraordinary rarity and cost. Most surviving examples are in long-term collections, museums, or private hands and rarely appear on the open market. Full provenance documentation and authentication by Mercedes-Benz Classic is essential. The coachwork varies dramatically between cars, as each was individually bodied. Mechanical restoration requires access to specialized pre-war Mercedes knowledge. Several high-quality reproductions exist. Any potential purchase at this level should involve the world's leading pre-war automobile specialists.
Only 33 chassis were produced between 1928 and 1932 at the Stuttgart-Unterturkheim factory. Each car received individual coachwork from various coachbuilders. Designed by Ferdinand Porsche during his time as Daimler-Benz chief engineer. Several lightweight variants (SSKL -- Super Sport Kurz Leicht) were built for factory racing use with drilled chassis rails. The SSK succeeded the SS and was the last of the great supercharged Mercedes sports cars.
