Some teams more efficient than others...
In an analysis of F1`s staggering annual costs, a British magazine has found that teams spend more than a combined $2.6bn each year.
To put the figure into perspective, Fiji records a similar yearly gross domestic product.
Citing insider sources and laborious research, F1 Racing said pitlane`s biggest spender in 2005 was Toyota, with a whopping half-billion dollar budget, ahead of Ferrari, spending $437m.

Drivers` and constructors` Champions Renault, on the other hand, also proved more efficient than McLaren, delivering the double crown on a $289m shoestring.

``F1`s annual spend is at a level that, in a post-tobacco world, can only be sustained by the car manufacturers,`` the specialist magazine contended.
