Mercedes Benz 700 SS


Mercedes Benz 700 SS 27/140/200 hp Fernandez & Darrin Torpedo
Introduced at the maiden Nurburgring 1000 km
race in 1927, the S-Type is considered Ferdinand Porsche's finest design for
Mercedes Benz. Although it was intended purely as a racer, the S-Type was
not designed from the bottom up as a racer, but developed from original road
going Mercedes models. At that Mercedes Benz however did not yet have a big
enough budget to allow them to setup a full bore race program, which many of
the company's Italian and British competitors did have.
Porsche based the S-Type on 400 and 630 models, which were named after their
displacement (almost 4 and 6.3 litre respectively). Both models were
equipped with six cylinder engines fitted with a supercharger that engaged
only when the throttle was floored. The official type indication of these
models included three horsepower figures, the first for the fiscal hp, the
second for the performance in natural aspirated form and the third indicated
the performance with the supercharger engaged.
It was the engine that made these Mercedes models interesting, as the
chassis and suspension were of a very simple design. One of the model's
biggest drawbacks was its size and weight. Agility was definitly not what
these models excelled at. A first step was taken in the right direction when
the K-Type was introduced in 1926. The K was an abreviation for the German 'Kurz'
or 'short' and indicated the shorter wheelbase compared to the 630.
Although the shorter wheelbase was an improvement, much more was needed to
provide the car with proper balance. What made the difference were the
modifications found on the first S-Type. The entire car was lowered and the
engine moved back in the chassis. Both were aimed at centering the weight,
which was beneficial for handling. In addition, the engine capacity was
increased to just under 6.8 litres. It was known as the 680 S.
Porsche's improvements paid off and the 680 S made its victorious run at the
first ever race on the Nurburgring. With 172 bends, handling is what the
25.6 km track is all about, underlining the S-Types fine cornering ability.
Larger engines were fitted to create the 700 SS and ultimately 710 SS. These
were intended for road use, but were almost identical to the now legendary
SSK and SSKL racers that were derived from the SS. True race cars for the
road, producing 225 bhp with the supercharger engaged.
