Mercedes-Benz Sport Roadster · S / SS / SSK / SSKL
Kompressor legends — S, SS, SSK and the featherweight SSKL.

The line progressed from the S through the SS to the shortened SSK (Kurz) and the featherweight SSKL (leicht), each iteration extracting more performance from supercharged six-cylinder engines and lighter, more focused chassis. Rudolf Caracciola's association with these cars cemented their legend, and the rarest variants — roughly 36 SSK and about 12 SSKL — remain among the most sought-after pre-war Mercedes-Benz machines.
Across eight years of production from 1926 to 1934, only 337 Kompressor sports cars were built. Their rarity, racing pedigree and Porsche-era engineering make the W06 family the bridge between Mercedes-Benz's competition heritage and the Silver Arrow Grand Prix program that followed.

4 distinct series across 1926–1934 — each identified by its chassis and engine numbers from period factory data.
