1926 Avions Voisin C11

Berline by Weymann
Chassis: 26366

Overview

The Avions Voisin C11 represents one of the finest examples of French engineering and design of the 1920s. Born from the visionary mind of aviation pioneer Gabriel Voisin, the C11 was a continuation of his desire to create an automobile that combined innovation, performance, and refinement. This model showcases Voisin’s dedication to silent, smooth motoring, drawing on his background in aeronautics and his adoption of the advanced Knight sleeve-valve engine.

Key Details

• Make: Avions Voisin

• Model: C11

• Body: Berline by Weymann

• Year: 1926

• Engine: Six-cylinder, Sleeve-Valve

• Displacement: 2,326 cm³

Historical Context

After WWI, Gabriel Voisin was forced to pivot from building aircraft to producing automobiles to provide continued employment for his skilled workforce. His transition was seamless, bringing with him the precision, aerodynamics, and innovative thinking that had characterized his aviation endeavors. The C11 was introduced in 1927 as the first Voisin model to receive a six-cylinder engine, placing it firmly at the top of Voisin's growing automotive range.

Voisin had already gained acclaim for his early models like the M1 (introduced in 1919), and he continued to refine the use of the sleeve-valve engine across the model lineup. The C11, with its 2.3-litre Knight engine, was a masterclass in engineering and became Voisin’s most commercially successful model.

Coachwork

This particular C11 features a Berline body by Weymann, a renowned coachbuilder known for using lightweight, flexible materials that resisted vibration and squeaks — a perfect match for the smooth-running Voisin drivetrain. Weymann bodies were a premium option in the 1920s, offering luxury, silence, and performance.

Technical Highlights

• Sleeve-Valve Engine: Known for its whisper-quiet operation and advanced design

• Six-Cylinder Layout: Voisin’s first foray into six-cylinder production

• Coachbuilt by Weymann: Lightweight and noise-dampened construction

• Innovative Heritage: Directly derived from aeronautical principles

Legacy

The C11 remained in production until 1936 and formed the basis for several derivatives. It was a symbol of engineering purity and one of the finest representations of pre-war French luxury cars. These vehicles were often favored by progressive thinkers, artists, and engineers due to their unique appearance and technical sophistication.

Condition

This example remains an exceptionally preserved piece of motoring history, ideal for concours display, Voisin gatherings, or long-distance touring. Its combination of originality, engineering excellence, and historical significance makes it a standout among vintage French automobiles.
