This car is a kit car based on the original model.
The SSK was the last car designed for Mercedes-Benz by Ferdinand Porsche before he left to found his own company.
The SSK is an evolution of the 1927 Modell S (S for Sport) which was based on the Modell K (K for "Kurzer Radstand" which means short wheelbase) variant of the Mercedes-Benz Typ 630.
The SSK chassis was 19 inches (480 mm) shorter than the Modell S to make the car even lighter and more agile for racing, especially short races and hillclimbs.
Fitted with a supercharged single overhead camshaft 7-litre straight-6 engine producing 200–300 metric horsepower (150–220 kW) and over 500 lb⋅ft (680 N⋅m) of torque (depending on the state of tune), the SSK had a top speed of up to 120 miles per hour (190 km/h), making it the fastest car of its day.
The supercharger on the SSK's engine was operated by a clutch that was engaged by fully depressing the throttle pedal and then giving the pedal an extra push. Backing off the throttle pedal disengaged the supercharger clutch.
