Overview

This was the most powerful 356B with, as its name suggest, an output of 90bhp thanks mainly to an increased compression ratio and the use of two twin-choke Solex carburettors.

Visually, it was upgraded in line with the entry-level B; the front bumper and headlamps were higher, while the indicators lenses protruded further and the handle on the bonnet became wider. New vents under the front bumper fed air to the brakes.

How to spot

Raised front bumper and headlamps. Wide bonnet handle. Vents under front bumper. Convex chrome hubcaps with Porsche badge in centre.

Variations

The 356B 1600 Super 90 was offered in Coupe, Cabriolet Hard-top Coupe (Cabriolet with a hardtop welded in place), Hardtop/Cabriolet (Cabriolet with a removable hardtop) forms.
