Why it matters
Vittorio Jano's Tipo B was the first single-seater in regular Grand Prix use and dominated the 1932 season. In Scuderia Ferrari hands it kept winning into 1935, including Nuvolari's famous German Grand Prix victory over the Mercedes-Benz and Auto Union teams.
How rare is it?
Six separate kinds of rarity – never combined into one number.
Each kind of rarity is rated separately and never combined.
02Production & history
Production
Every figure says what it counts.
| What is counted | Figure | Basis | Status |
|---|---|---|---|
| Total model productionTipo B cars as stated on the museum page (which describes the 2,654 cc 1932 specification) | 61,2 | Factory production | Factory reported |
Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.
History
Built for the 1932 Grand Prix formula, the P3 used a bifurcated drive with two propshafts in a triangle either side of the seat, allowing a lower driving position. Nuvolari and Caracciola won almost everywhere in 1932. After sitting idle in early 1933 the cars passed to Scuderia Ferrari, and for 1934 they received wider bodies and a 2,905 cc engine. A further enlarged engine was fitted in 1935, when Nuvolari beat eight German cars at the Nürburgring.
