Mercedes-Benz SLK 230 Kompressor (R 170)
The first SLK could change from a snug steel-roof coupé to an open two-seat roadster, while a supercharger helped its four-cylinder engine pull hard.

More than a set of wheels.
Mercedes-Benz showed an SLK study in 1994, revealed the production R 170 at Turin in April 1996 and launched it that autumn. Its signature vario-roof folded a steel roof into the boot, offering open-air driving without leaving a fabric roof exposed when parked. The SLK 230 Kompressor paired that idea with a supercharged 2.3-litre engine, compact dimensions and structural reinforcements developed specifically for an open body.
Look a little closer.
SLK abbreviates the German words for sporty, light and short—and the car was under four metres long.

One roof, two kinds of car
The vario-roof was not a removable panel. Electrohydraulic hardware folded the steel roof into the boot, giving owners the weather sealing of a coupé and the open sky of a roadster in one car.

Without a fixed roof, the floor, sills, tunnel and cross-members had to resist bending. Mercedes also nested reinforcing tubes in the A-pillars and used an ellipsoid bulkhead to manage frontal forces while protecting the footwell.
