The Bertone-Porsche partnership was reaffirmed in the 1990's after the spider/roadster on a 911 chassis of the mid 1960's, which was presented to the public at the 1966 Geneva Motor Show. 25 years and many changes in styling trends and tastes later, the Porsche 911 proved that it had stood the test of time, and at its relaunch showed more aplomb than ever. The identity and personality of the 911 were so marked that Bertone decided to avoid any comparison to the specific sports coupé in question and devoted his energies to designing a classy saloon. The project evolved with the intention of creating a design that would be feasible in terms of size and functionality. Bertone's Karisma was designed as a high performance saloon car, and its styling was characterised by deep swage lines running along the wings, a transparent roof and the large gull-wing doors incorporating the entire wings, an idea which had come about in 1967 for the Marzal prototype on Lamborghini mechanics. As a whole, the Karisma affords the onlooker a generous view of its interiors through the ample glazed surfaces, which also feature on the engine compartment. As for the interiors themselves, any unnecessary features were eliminated, enhancing the sensation of comfort and well-being. The result is a four-seater saloon with a rear-mounted engine with many futuristic functions and design features.
