[3][4][5] The idea of creating these cars was feasible thanks to the revolutionary regulations imposed at the end of the 60s in order to generate an evolution within the category, a product of the fact that they had been competing since the 40s with the same units of that time.

This extensive regulation opened up a true range of possibilities for both pilots and trainers to compete with models designed to their liking and convenience, and combining elements from different brands.

In 1966 and attentive to what was happening in Road Tourism with the arrival of the first compact cars, Industrias Kaiser Argentina decided to enter the aforementioned category, presenting a completely new model: the IKA Torino.

The first official team was under the command of the renowned trainer Horacio Steven (who in 1968 would obtain the title for preparing the Thunder Orange Chevrolet engine), who did not have much brilliance in the direction of it.

Pronello undertook the construction of a pointed design nose on reinforced fiber, which ended up giving his car a highly aerodynamic cut.

At that time, the Hare Mk I, apart from its revolutionary trunk, had been equipped with a new suspension system that allowed it to have a better hold on the road compared to its "big brother".

Ford was the first to respond to Berta and Pronello's proposal, putting the Baufer-Ford on the track, a prototype designed by Alain Baudena and used by the firm for its official team.

From Chevrolet, the most attractive models began to appear, such as the evolution of the Chevitú created by José Froilán González and used by the official squad, the Garrafacreated by the Bellavigna brothers and driven by Andrea Vianini or the Barracuda-Chevrolet used by Carlos Paretti.

La Liebre Mk II marked an important domain and took the championship with Eduardo Copello from TC, who was the first champion with a brand other than the traditional Chevrolet and Ford.

Oreste Berta had managed to get hold of two of these units by creating his own structure, which was sponsored by the lubricant firm Bardahl and led by Eduardo Copello and Nasif Estéfano as pilots.

This year, Copello and Gradassi would each try on their own to defend the honor of Torino, however, their attempts were in vain before the onslaught provided by the Orange Thunder with Carlos Pairetti at the wheel.

He decided to redesign the body of the Hare Mk II, modifying the roof drop at the rear, giving it a sharper profile and higher drag coefficient.

As for other items such as the suspension or the chassis, the new design maintained the characteristics of its predecessor, the torpedo, and the location of the seats being reformed, among others, to improve weight distribution.
