Toyota TF106B

Active: 25-05-2006 - 2006
Team: Toyota Motorsports GmbH

Team: Pascal Vasselon (TD)
Drivers: Jarno Trulli (7), Ralf Schumacher (8)

After having run the first 6 races of 2006 with the TF106, Toyota moves in the updated B version which completes the major development steps in 2006. Apart from changes with the fuel tank, an updated aero package and a revised front suspension, the cars characteristics are the same as its predecessor, the Toyota TF106.

The TF106B represents the final step of the evolution that started at last year's Japanese GP when the new front suspension was introduced on the TF105B model. It has a new chassis with no keel in the middle in an effort to exploit all the aerodynamic advantages of the new layout. It also has new suspension geometry with a different push rod angle. This forced the introduction of small "alligator eyes" on top of the chassis for the rocker pick up point."

The Toyota TF105 and TF106 kept the same wheelbase with the addition of a spacer between the engine and chassis (2) to cope with the shorter V8 engine for 2006, reducing the general stiffness of the assembly.

The new TF106B chassis has a longer fuel tank (1) to compensate for this difference in length so the chassis length remains unchanged.
