First, our engineers had to define what the meaning of ‘fun to drive’ before testing rival cars against the IS at Toyota’s Higashi Fuji proving grounds. Using several parameters like steering, breaking or speed sensation, the team could determine how ‘fun to drive’ the new IS was.

The amazing thing about this is that they test cars from other manufacturers, to find out in which direction the market is going in terms of vehicle ride, comfort and handling. Through this, Toyota sets a rank of performance targets which will help to position the product according to the level that they want to reach, giving a final result which appeals and satisfies the customer.
