The 356B, produced from 1960 through 1963, represents the mid-point in this design's progression. In what is known as 'T5' form, the B introduced new front and rear sheet metal, while retaining the curved front trunk lid and rounded fenders of the 356A series. The B also added some features demanded by American customers, such as raised front and rear bumpers with over-riders to better protect the body from parking mishaps. The headlamps were raised, a larger hood handle added, and front vent windows appeared in the doors. Mechanically, the gearbox and drum brakes were upgraded. A new steering wheel and column refreshed the interior, along with redesigned rear seats. A 'Super' model with raised compression added an extra 15bhp over the standard version, while the even hotter Super 90 added 30bhp – a full 50% more power than the base car.
