CornuTwin-Buchet Voiturette
Production1904–1908
Recorded originFrance
ClassUltralight open two-seat voiturette
Paul and Jules Cornu's sole automobile design, photographed at Lisieux in 1904 and subsequently marketed under the Cornu name from 1905. Its unusual twin-engine layout sent each Buchet single's power by belt to a rear wheel, avoiding a conventional shared drivetrain. The 80 km/h figure is repeated in standard marque references, but engine dimensions, combined output, starting and synchronization controls, steering, brakes, suspension, wheelbase, weight, price, bodies beyond the photographed voiturette and surviving examples remain unresolved. Later helicopter experiments are inventor history, not separate road models.

Record depth — Documented
How this is measured → This record contains useful sourced evidence, but it does not yet meet the reference-ready standard. Still needed: attributed imagery. Fields we cannot source stay empty rather than guessed.
Research notes
Output is unknown and likely very small; the surviving family photograph proves the 1904 prototype but no serial or sales ledger survives.
