The change from 1.5 liter engines in 1965 to 3 liters in 1966 was a turbulent one. BRM thought that they could one-up the competition, by combining two 1.5 liter flat 8 engines into one, large H16. Since the flat 8 was already tried and tested, they thought that the new engine could be developed quickly, and with far greater power than anyone else could imagine.

The sad result was a tricky, fragile and very heavy engine. Combining the two engine blocks required a redesign, the extra gearing to connect the two suffered frequent breakages, and the combination of the two flat 8s was far more than the weight of two of the old engines. The only victory was in the back of a Lotus at Watkins Glen in the hands of Jim Clark in 1966. During the 1967 season, BRM decided that the project was a failure, and focused on a V12 engine that the company had successfully developed for sports cars. That basic V12 design would power BRM cars until the company folded, 10 years later.
