1959-1962 B Porsche 356 B Roadster
Overview
The 356 B Roadster occupied a distinct market position between the practical cabriolet and the minimalist Speedster, produced from 1959 through 1962 in limited quantities that remain small relative to coupe and cabriolet output. The roadster represented a middle ground between full convertible equipment and stripped-down open-air machinery, providing weather protection elements without the mechanized top systems or elaborate interior appointments found on cabriolets. Different tail light designs distinguished US-specification examples from rest-of-world variants, a cosmetic detail reflecting regional regulatory requirements and aesthetic preferences. The roadster's production window proved relatively narrow, as market demand never justified extended manufacturing commitment despite the model's technical merit and capable performance characteristics.
The 356 B Roadster served customers seeking open-air motoring with greater weather protection than Speedster variants yet valuing simplicity and manufacturing cost reduction compared to full cabriolets. The model's intermediate positioning created operational compromises acceptable to specific buyer profiles while generating insufficient demand to justify permanent production commitment. Factory planners understood that the roadster occupied marginal market space, sustained by enthusiast demand insufficient to generate volumes supporting dedicated manufacturing processes. The eventual discontinuation reflected rational business decisions rather than engineering inadequacy, as declining orders could not justify continued tooling and specialized manufacturing effort.
Engineering & Development
The 356 B Roadster chassis incorporated proven components and assemblies from contemporary coupe and cabriolet production, minimizing manufacturing complexity through standardized parts sharing across the model lineup. The soft-top mechanism employed simplified mechanical linkages compared to cabriolet designs, reducing manufacturing cost while accepting reduced operational convenience. Windshield assemblies received modification from coupe standards, with reduced height and simplified frame structures accommodating open-body configuration requirements. Tail light treatment received special attention from factory designers seeking solutions that improved functional performance while accommodating regional regulatory requirements across different markets.
Engine development paralleled coupe variants without special modification, as the roadster's light body weight conferred inherent performance advantages that compensated for modest horsepower figures. Cooling systems required no enlargement compared to fixed-roof models, with the open configuration and reduced body mass supporting adequate heat rejection. Suspension geometry remained identical to contemporary specifications, with no modifications required to accommodate the roadster's reduced structural rigidity compared to coupe variants. Braking systems utilized standard drum brake assemblies, with no special provisions for the roadster's specific configuration characteristics.
Market Variants
The 356 B Roadster existed in limited variations reflecting the model's constrained market position and limited production commitment. Base and Super engine options remained available, providing horsepower differentiation consistent with broader model lineup strategy. The US market received lower-compression base engines while rest-of-world customers accessed higher-output variants without compression restrictions. Optional details proved minimal, with customers essentially selecting engine output and interior trim level as primary specification choices. The roadster never achieved sufficient production volume to justify elaborate option packages or customization possibilities available on other variants.
Sales distribution concentrated among enthusiast buyers seeking open-air motoring without cabriolet pricing premiums or Speedster-level austerity. European customers represented the dominant market, with German and Swiss buyers particularly receptive to the roadster's balanced approach to weather protection and minimalist design. North American sales remained modest, as American customers generally preferred either full cabriolets or appreciated the Speedster's extreme simplicity without accepting roadster's intermediate compromises. Production never exceeded several hundred annual units, constraining total B-series roadster output to modest volumes insufficient to create widespread dealer availability or brand awareness among casual enthusiasts.
Significance
The 356 B Roadster represented Porsche's attempt to serve intermediate market positioning, discovering through market response that the particular combination of features the roadster offered attracted insufficient demand to justify continued production investment. The model's discontinuation reflected realistic business assessment rather than engineering failure, confirming Porsche's pragmatic approach to product planning and manufacturing resource allocation. The roadster's brief production history established that market segmentation had practical limits, with too many variants creating complexity that eventual production consolidation would eliminate.
The roadster's rarity in contemporary context reflects limited original production and selective preservation during subsequent decades. Few surviving examples exist relative to contemporary coupe and cabriolet production, making the roadster notably scarce among 356 variants. For collectors, the 356 B Roadster represents a market experiment that ultimately proved unsuccessful, capturing a moment when Porsche explored variant strategies later abandoned as inefficient. The model occupies an overlooked niche in Porsche history, lacking the established market position of coupes and cabriolets while missing the minimalist authenticity that contemporary enthusiasts associate with Speedster variants.
