Special attention must go to Ferrari's five awesome development vehicles built to take the GTO concept to it's limit. Designated GTO Evoluzione's, these experimental cars were originally conceptualised as the 288 competition variants that would contest Group B. However, they later took on the role of mobile test beds for the technology that would be incorporated onto 1987's F40. With the Evoluzione, Ferrari greatly increased their use of composite panels on a chassis that was still closely related to the 288 (steel tubes and composite reinforcements).
   
Higher cabin sill extensions were especially noticeable from within the cockpit and were retained for the F40. The first engine plumbed into an Evoluzione was designated Tipo F114 CR and featured the turbo pressure cranked up to 1.4 bar (compared to 0.8 bar for road car), compression being increased to 7.8:1 from the 288's 7.6:1. These changes alone resulted in a reliable power hike to 530bhp at 7500rpm. The R in it's engine designation referred to the fact that these units were originally intended for use in Rallying - a site that is hard to imagine with the mass produced sedans that dominate WRC events today. The next development, Ferrari's Tipo F114 CK (K to designate a circuit engine) featured an even further enhanced specification. Thanks to larger diameter IHI turbochargers, power soared to a Grand Prix-rivalling 650bhp at 7800rpm! Combine such figures with the ultra light 940kg weight (the original 288 GTO weighed in at 1220kg) and a cocktail of almighty performance was complete. Depending on gear ratios, a top speed of 225mph was reputedly possible while sprinting from zero to 125mph took less than ten seconds. As was becoming commonplace in top level competition cars, composite panels were used for the entire Evoluzione shell, the lines of which had significantly evolved from the lithe elegance of Pininfarina's original 288.

The nose seemed to have been influenced Pininfarina's Series II and III BB LM's, the Michelotto 308 GT/M's of 1984/’85 and perhaps most surprisingly, the Facetti-modified Group 5 308 CARMA. Deeper side skirts minimised air flow underneath the car, the only really obvious similiarties with the 288 having come around the doors, windscreen and cockpit sides. As had been the case at the front, the rear bodywork was fashioned purely with function in mind, a multitude of ducts and louvres finding their way onto the doors, screen, deck and wings.
   
250 GTO-style louvres were cut deep into the rear wings while a phenomenal array of vents were located on the rear quarters and perspex screen, many of many of which went on to be used for the F40. The aero pack was completed by a huge fully adjustable rear wing complimented, at it's base, by a supplementary gurney flap. As you would have expected, the interior was bereft of anything considered unnecessary in the pursuit of ultimate performance. The only similarity to the original 288 cabin was the instrument binnacle, everything else having been subtly redesigned and later incorporated more or less directly into the legendary F40. Ferrari had originally intended for 25 GTO Evoluzione's to be constructed, that number being FISA's minimum requirement for qualification of race legal Evoluzione's should Ferrari have wanted to participate in Group B circuit or rally racing with the car. In fact though, only five were ever built as a result of FISA scrapping the regulations after several horrendous driver and spectator fatalities - Group B had become too fast and too dangerous to survive. In conclusion, there have been a number of look-a-like GTO Evoluzione's built up over the years, but the chassis numbers of the five original examples are listed below:
