Fernando Alonso has the lightest car on the grid for Sunday's Chinese grand prix.

The Spaniard, but not his teammate Nelson Piquet, was fitted with a 'double diffuser' for qualifying, and he said qualifying on the front row was "unbelievable".

But when the FIA published the car weights on Saturday evening, it emerged that Alonso's car has just 32 kilograms of fuel on board -- more than 20 kilos less than the Brawns.

The Red Bulls are also quite light: pole sitter Sebastian Vettel is just 8kg heavier than Alonso's car, while Mark Webber is carrying two additional kilos than his teammate.
