The constructors' championship hots up 25 Sep 2005
The drivers championship has been sewn up with Fernando Alonsos third place in Brazil - giving him an unassailable lead in the table. But the constructors championship is still wide open - indeed, post Interlagos, it looks a good deal closer than before.
McLarens 1-2 finish brought the team a well-deserved 18 points, which actually puts them ahead of Renault in the championship standings - 164 points to 162. With just two races of the season remaining either team could emerge with the title - and both will be expecting their drivers to dedicate themselves to winning it.
Michael Schumachers strong drive to fourth place in Brazil, together with Rubens Barrichellos sixth, have also helped to give Ferrari an increasingly comfortable lead over fourth-placed Toyota in the Constructors Championship. With 98 points to Toyotas 81, the Italian team will be optimistic that they can keep their position to the end of the season.
Further down the order Williams fifth place looks relatively safe - with 59 points the Grove-based team enjoys a 26 point margin over sixth-placed BAR. Not that BAR can feel anything like as confident in maintaining their position - Red Bull Racing are just six points behind.
Sauber, Jordan and Minardi - eighth, ninth and tenth respectively - will all be lucky to score large numbers of points in any of the remaining races and so look set to get to the end of the season in the same positions.
