02Production & history
Production
Every figure says what it counts.
| What is counted | Figure | Basis | Status |
|---|---|---|---|

Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.
History
For the 1966 Formula One season the engine limit rose from 1.5 to 3.0 litres. Lotus fitted the 43 with BRM's H16 engine, which was two V8 units stacked on top of each other and geared together, with eight camshafts. It was much heavier than the V8 and V12 engines of its rivals.
The H16 managed to finish only one race, the 1966 US Grand Prix at Watkins Glen, which Jim Clark won.
BRM dropped the H16 for 1967, and Lotus switched to Cosworth engines that year.
