The final grand prix of the season was one of the most exciting of the year, but from a technical point of view it was probably the least.
Being both the last race and one in a series of fly away races, most teams did not appear with any significant updates to their car. Development has long since moved onto 2009 and McLaren were the only exception with a package developed specifically for the final race.
Interlagos runs anti-clockwise and is formed of three distinct sectors, the first and last being largely flat out blasts down long straights, with a slow and twisty section in the middle. This gives the teams a choice of aero strategies: either a loInterlagos is still no Monza, so even the lower downforce setting is a medium level and uses a heavily-twisted rear wing to reduce the induced drag and aid top speed.
The Brazilian track is also notorious for its bumps, although this problem is negated by the lack of fast turns, which might otherwise demand a stiff suspension.
