Budgets 2008
It is generally known that in 2006 engine budgets peaked. It was due to the introduction of the V8 engines and no engine freeze. The likes of Toyota, BMW, Honda and Renault are estimated to have spent well over $200m just for engines that year. The 2008 figures show the financial capabilities of the manufacturers at the hight of the cost race. If you want more sources you can buy the Formula Money report for that year. I'm not spending that money so I don't have the exact figures.Toyota: $445.6m
McLaren: $433.3m
Ferrari: $414.9m
Honda: $398.1m
Renault: $393.8m
BMW Sauber: $366.8m
Red Bull Racing: $164.7m
Williams: $160.6m
Toro Rosso: $128.2m
Force India: $121.85m
Super Aguri: $45.6m
Total: $3,073.45m
Manufacturers do not spend engine development money to help their customers but to push their own works team. They generally supply inferior specs to their customers unless they are prohibited by homologation to do so. Fota have negotiated capped engine prices in the past to recognize those facts. There is enough precedent to believe that there will be a kind of market regulation in 2014 again. Preferably they will operate under engine cost cap.
