BRM engine designer Tony Rudd opted for the bold expedient of flattening two of the company's successful 1.5 liter V-8s and gearing them togetner one atop the other.
Sadly the H16 proved horrendously unreliable at first: no sooner had one source of internal vibration been eliminated than another would begin to wreak havoc. The H-16 only began racing toward the end of 1966 and even though it was more reliable it lacked the expected power.
It was dreadful recalls former BRM star Jackie Stewart. " It was so bad, it only changed when you got to really difficult cicuits such as Spa or Nurburgring..But it was just terrible.
The H-16 engine did win a Grand Prix, however. Before the Ford DFV was ready for 1967 Lotus cheif Colin Chapman did a deal with BRM to use it's H16 in 1966 in his type 43.
Maurice Philippe and the Lotus design team knew they were in trouble when the first engine arrived and four men were needed to lift it off the truck..investigation discovered it weighed as much as the rest of the car.
However at Watkins Glen that year Lotus borrowed the works spare engine after it's own had blown up in practice and in the race Clark nursed his Lotus-BRM to a suprise triumph. It was the only race ever won by a 16 cylinder engine.
