🚗 CAR OF THE WEEK: 1927 AVIONS VOISIN C7 CHASTNESS
Designed by French aviation pioneer Gabriel Voisin, the C7 applied lessons from aircraft construction to the automobile: lightweight materials, clever engineering and a relentless focus on efficiency.
Our 1927 C7 is powered by a 1,551cc sleeve-valve four-cylinder engine, often called a “Silent Knight” for its unusually smooth and quiet operation. It also features a three-speed gearbox with a two-speed transfer case, giving it six forward speeds and two reverse speeds.
The aviation influence goes far beyond the mechanics. Its lightweight body uses fabric stretched over a wooden framework, while carefully placed luggage trunks helped balance weight. Even the roof was designed narrower than the body, following Voisin’s belief that you needed less room for your head than your arms.
Look closely and you’ll find details everywhere: sliding side windows, a leather-strap interior door latch, aircraft-like fittings and Voisin’s famous La Cocotte hood ornament.
Only about 1,350 C7s were produced from 1924 to 1928.
It is part automobile, part aircraft philosophy and unmistakably Voisin.
