#10 BRM P75, 16 cylinder H 3.0L (4 GP, 9 points, 1 victory)
Only its miraculous victory thanks to Jim Clark and Lotus in the United States saved it from free-falling in the championship rankings. No one knew what the BRM engineers had imbibed when they came up with the P75 engine for the 1966 season. A proper white elephant with two 180° 8 cylinders with the two connected crankshafts, resulting in an unlikely H16! While it had honourable power, it was as fragile as peanut brittle. So frail was it, only Jimmy was able to finish a Grand Prix at Watkins Glen.
