Porsche 356 Speedster buyers could get their sports car in two outputs from the factory. Both versions used a 1.6-liter flat four-cylinder engine and a four-speed manual. In base form, the mill made 60 horsepower (44 kilowatts), but the S variant, sometimes called the Super Speedster, pushed the number to 75 hp (56 kW).

While this doesn't sound like much by modern standards, the stripped down Speedster's lower weight made the most of the modest output.
