If the S-type was mind-numbingly fast for its time, the SS was LHC-like electron fast thanks to its advanced supercharged 6-straight petrol engine that delivered 200 hp and 225 respectively throughout its production time.
Now, taking into consideration that most cars of the time, even other MB models boasted a power output not higher than 80 hp for the sports models, this very limited range of automobiles was as fast as some of the cars today. In fact, the quickest SS-model reached a top speed of 118 mph (170 Km/h), amazingly achieved through a low compression ratio(6.2:1) and supercharger combination.
