1959-1963 B Porsche 356 B Cabriolet
Overview
The 356 B Cabriolet continued Porsche's open-air philosophy from 1959 through 1963, applying refinements developed during the A-series evolution to the convertible platform. The soft-top configuration maintained mechanical simplicity while benefiting from improved materials and manufacturing techniques that enhanced durability and weather protection compared to earlier variants. Bumper styling represented the most visible distinction between US and rest-of-world specifications, with American markets receiving more substantial bumper designs reflecting federal safety considerations and customer preferences for obvious protection. The cabriolet remained a commercially viable variant, though production volumes consistently trailed fixed-roof coupes as practical considerations and weather concerns influenced purchasing decisions in temperate climates.
The 356 B Cabriolet occupied established market space previously defined by successful A-series convertibles. Factory engineers understood that open-air motoring remained desirable for affluent customers in favorable climates, yet recognized that northern European markets showed preference for closed bodies during winter months. The cabriolet's continued production reflected this regional demand variation, with manufacturing capacity allocated to satisfy Mediterranean, southern French, and Alpine customers who enjoyed extended driving seasons. North American sales of cabriolets grew during the B-series period, reflecting increasing enthusiasm for sports car ownership among wealthy Americans and expanding dealer networks capable of promoting convertible variants.
Engineering & Development
The 356 B Cabriolet chassis evolved modestly from A-series specifications, incorporating the same suspension refinements and mechanical improvements applied to contemporary coupes. The soft-top mechanism received attention from engineers seeking improved reliability and ease of operation, with refined mechanical linkages reducing stiction and improving consistency. Canvas materials and rubber seals improved through supplier advances and manufacturing process refinement, reducing water infiltration and improving longevity. The windshield assembly received modifications paralleling coupe development, with improved sealing and larger glass areas enhancing forward visibility and reducing wind noise at highway speeds.
Engine development proceeded identically to coupe variants, with improved cooling efficiency and refined fuel system management supporting marginal power increases. The cabriolet platform actually benefited from lower overall mass compared to fixed-roof coupes, resulting in slightly better power-to-weight ratios that compensated for modest horsepower figures. Structural bracing throughout the chassis addressed torsional rigidity requirements, with reinforced door aperture frames and transmission tunnel extensions maintaining handling characteristics equivalent to contemporary coupes. Cooling systems required no special enlargement compared to fixed-roof variants, as the reduced body mass and improved air circulation through open configuration improved natural heat dissipation.
Market Variants
The 356 B Cabriolet followed identical specification strategy as contemporary coupes, with regional horsepower differentiation and optional trim levels representing the principal variables available to customers. The US market received lower-compression base engines with higher-output Super variants available for customers prioritizing performance. Rest-of-world markets accessed the full range of engine specifications without compression restrictions. Optional details remained minimal, with customers selecting upgraded interior appointments and improved sound-deadening treatments as primary enhancement options. Factory policies maintained cabriolet availability as standalone offering rather than exclusive conversion available only to coupe customers.
Sales distribution concentrated in markets with favorable climate characteristics and strong sports car purchasing traditions. Mediterranean region sales remained strong, with French and Italian customers viewing the cabriolet as practical conveyance for summer motoring. Central European sales reflected similar demand patterns, with Swiss and Austrian customers purchasing cabriolets at consistent rates. North American uptake increased during the B-series period, as American wealth and leisure culture began shifting toward recreational automobile ownership. Scandinavian customers purchased cabriolets occasionally despite cool climate profiles, suggesting strong enthusiast commitment to open-air motoring among northern European sports car buyers.
Significance
The 356 B Cabriolet demonstrated that soft-top configurations could remain viable production offerings across multiple generations of model development. The continued investment in convertible engineering and manufacturing capacity confirmed Porsche's commitment to open-air motoring as legitimate expression of sports car philosophy rather than afterthought variant. The cabriolet's production through multiple B-series generations established permanence within the model hierarchy, creating precedent for convertible continuation in subsequent 911-based generations.
The cabriolet's commercial success influenced Porsche's subsequent thinking regarding variant development and market segmentation. Factory strategists recognized that different customer preferences and geographic markets supported distinct body configurations, informing decisions to maintain multiple body styles rather than concentrating production on single core design. For contemporary drivers, the 356 B Cabriolet represents a refined expression of convertible sports car philosophy, offering improved weather protection and mechanical sophistication compared to earlier Speedster variants while retaining the essential character of driver-focused open-air motoring that defined the marque's foundational period.
