With the help of our star driver in those years Hessel Roskam (HR) we defined for 2008 the car that has been the true base of the last Neox cars. The Neo 2.5HR presented a renovation of the 80% of the pieces of the Neo 2. The anti-roll bars and the transmission were renovated, a new geometry of suspensions and new Ackerman angles were used for the first time. With this car a new path that would evolve towards the present models of Neox was opened.
