F1: Toyota TF106 Bahrain aero


Panasonic Toyota Racing has unveiled a new aerodynamic package for its TF106 race car ahead of the season-opening grand prix in Bahrain. The new package has been introduced in time for the final two pre-season tests in Vallelunga and Barcelona and will make its debut at the Italian track on Tuesday 14 February. This feature outlines the major differences between the TF106 that has been testing since the end of November 2005 and the version that will race in Bahrain.

Side pods
The major differences between the car used in winter testing and the one used at the Vallelunga test are concentrated in the side pods
1) New turning vanes with little vertical splitter and a second little
gurney flap (2) attached to the horizontal fin with a modified shape
3) The side pods are much narrower in the low part to match the reduced
cooling needs and to improve the airflow to the rear of the car
4) Winglets are new and smaller than the previous ones
5) New chimneys are mounted with an increased angle towards the oustside and are integrated with new winglet of the side pods

Front Wing

The new aero package starts with a new front wing, based on the 2005 Monaco front wing that already had a second small wing (2). The new version also includes a small fin on the inside (1) and also on outside (3). At the side of the nose cone there are 2 additional fins (4). The first two fins (on top) were introduced already at the start of the 2005 season.
