The Neo 1 was the first commercial Contrast in history. It was launched in October 2004 having already won the Spanish Championship in its prototype phase. It marked a new way of designing large scale cars and it was the pioneer of the new era of modern cars. It reduced the regular weight of the category in almost two kilos with its 9,6 kilos opposite the 11,5 kilos of other models. It innovated thanks to its system of mobile ballasts, with its system of fixation of the wishbones axles, with its servo saver or with the assembly of the wishbones over the rear mounts, concepts that have been copied several times even in the most brand new cars. Being our first car there were also some details to improve that made us evolve towards the Neo 2.
