, the P25's design emphasized simplicity. The car was fitted with a 2.5-litre straight-4 engine, producing some 275 horsepower. The P25 would be the foundation of BRM's successes in the late 1950s and early 1960s.

Development

With BRM in financial trouble after the V16 experiment,

at the front wheels, which would later be replaced by Dunlop discs. Uniquely, a single brake disc was fitted to the gearbox at the rear.

Racing record

The P25 began racing in non-championship events in September 1955. The car's horsepower proved to be its strong suit, but its handling and reliability problems were quickly revealed. Three Type 25s were entered for

Joakim Bonnier placed BRM 4th in the inaugural Constructor's Championship. Bonnier took his and BRM's first victory at the 1959 Dutch Grand Prix. With the P25 running reliably, BRM was able to secure 3rd in the Constructor's Championship. Just as the P25 became reliable, Cooper started the rear-engine revolution and quickly rendered front engined cars such as the P25 obsolete. BRM began work on a rear engined model, the P48 not long after Bonnier's victory. The P48 would replace the P25 midway through the 1960 season
.

In addition to the factory entries, the British Racing Partnership ran a P25 for Stirling Moss and Hans Herrmann in 1959. Moss scored a 2nd place in the British Grand Prix before the car was destroyed in a massive accident during the German Grand Prix with Hermann at the wheel.
