The mirrors are pushed way out on the sidepods, where they actually give the driver a decent view of what's happening behind him. They are actually more practical than obligatory.
The rear wing is a complex curve, like renault. Last year it was constanc chord, but like renault, now a more complex shape to accomodate the different types of airflow it deals with..eighter fromt he chassis in the middle, or on the sides where the air is less dirty.
The "chimneys" appear very thin, probably to the extent they don't allow the vent of air. They are now more guide vanes than exits for hot air.
They also got rid of the small guide vane on the outside of the radiator inlets.
This is the car they ran in the last race of the '05 season.
