Bonneville5 CV Voiturette
Bonneville's distinct purpose-built light car used a tubular chassis, rear-mounted De Dion-Bouton engine, three-speed transmission and lever steering rather than the Train-Cycle's removable forecar conversion. Two- and four-seat tonneau or vis-à-vis bodies were offered, with wood or metal wheel rims and 700 × 80 tyres; the reported selling price was 4,500 francs. The catalog uses the contemporary power rating as a transparent model label because no factory type name survives. Its 1897–1900 dates are the marque's automobile-production span; only a 1900 illustration securely dates this specific form, so annual availability is not inferred.
Dates with their meaning intact
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.
