The Type 25 was BRM’s second car after Type 15 V16 designed in 1950. The P25 began racing in non-championship events in September 1955, and was used by works team until beginning of the 1960 season. The car designed by Tony Rudd used an extremely oversquare (4.05 x 2.95 in, 102.87 x 74.93 mm) 2.5 L atmospheric four-cylinder engine designed by Stewart Tresilian. The P25 was initially unsuccessful, not winning a race until a victory at the Dutch Grand Prix in 1959. This win was a greatest achievement in Formula One for Jo Bonnier, who spent 16 seasons in F1 from 1956 to 1971.
