Avions Voisin C11 classic cars for sale

History of Avions Voisin C11

Introduced at the end of the 1920s, the Avions Voisin C11 was developed by Gabriel Voisin, a pioneer known for both aeronautics and automobile innovation. Voisin translated his expertise in aircraft construction into the automotive realm, utilising lightweight aluminium and innovative engineering solutions. Produced in France, the C11 encapsulated the ambition to provide both technical finesse and an avant-garde aesthetic, embracing the Art Deco movement that strongly influenced many French luxury goods during this era.

Model History of the Avions Voisin C11

The C11 was presented as an evolution of Voisin’s ongoing pursuit of lighter and more technically advanced automobiles. It succeeded the earlier C5 and C7 models, and applied learned advancements in streamlined bodywork and engine refinement. The series focused on combining aeronautical principles such as extensive use of alloys and rational weight distribution, resulting in a vehicle that was both robust and noticeably comfortable for its time.

Highlights of the Avions Voisin C11

Key features of the C11 include its extensive use of aluminium body panels, pioneering silent-block mountings to reduce vibration, and the unmistakable Art Deco interior appointments. Voisin’s dedication to innovation extended to patented mechanical solutions, such as advanced door locking systems and uniquely styled dashboard elements. The C11 was often bodied by master coachbuilders, allowing for customisation and exceptional craftsmanship.

Technical Data

Special Editions and Collectible Models

Some C11s were built as bespoke models by renowned coachbuilders, introducing unique bodywork variants such as coupé de ville, torpédo, and berline configurations. These special editions distinguished themselves with details such as two-tone paint schemes, bespoke upholstery, and occasionally commissioned mascots or radiator ornaments, tailored for discerning clients.

Weak Spots and Common Issues

Documentation and spare parts availability remain points to consider, as with many vehicles from the interwar period. Sleeve-valve engines demand regular attention to maintain proper sealing and lubrication. Chassis corrosion and wear in the suspension bushings are particular areas for pre-purchase inspection, especially given the non-standard materials used compared to more mainstream contemporaries.

Engine and Performance, Transmission and Handling

The C11’s straight-six sleeve-valve delivers refined and vibration-free power, suited to relaxed cruising over long distances. Weight-saving measures and innovative suspension yield surprisingly compliant ride characteristics for the era. The manual four-speed transmission is direct, and hydraulic brakes on later versions increase driving confidence.

Popular models to highlight include the custom coachbuilt ‘berline’ and ‘coupé de ville’ variants, often selected for their elevated comfort and luxury features. Technical details: 2.3-litre straight-six, four-speed manual gearbox, and mechanical or hydraulic brakes depending on year. undefined

Interior, Comfort, Exterior and Design

Inside, the Voisin C11 is defined by uncompromising luxury and Art Deco motifs. Upholstery often incorporated patterned fabrics, nickel-plated fixtures, and geometric dashboard dials. Externally, bodywork was characterised by angular lines and prominent aerodynamic touches—a direct influence from Voisin’s aviation background. Owner-customised details, such as folding tables and specially sourced leathers or woods, were not uncommon.

Other Relevant Features

Some C11s delivered features unusual for their day, such as advanced soundproofing and early adoption of safety glass. Owner records show use of rare coachbuilder signatures, making each surviving C11 distinct in architectural and trim details.

Summary

The Avions Voisin C11 represents a holistic approach to motoring, where technique and style are intertwined. Its market presence is singular within the Avions Voisin brand, commanding attention for both its technical ingenuity and highly personal design philosophy. The C11 remains a significant representative of French motoring excellence from the interwar years.
