The stunning Ferarri 288 GTO

Based on the 308 GTB chassis, designed by Pininfarina, the 288 GTO was to be Ferrari’s bid for Group B competition. The major differences between the two are some styling cues but more importantly the engine and layout. Due to Group B’s displacement rules, the 308’s V8 2927 cc motor was de-bored to 2855 cc since it was Ferrari’s intention to turbocharge it. The rulebook mandated a multiplication factor of 1.4 for forced induction engines. Thus, the new smaller turbo engine would have a final cc rating of 3997, putting it in the 3000~3999 cc class (which dictated maximum tire widths and minimum curb weight). In this instance, the 288 GTO could run a maximum tire combination width (for one side of the car) of 24 inches and have a minimum curb weight of 1,100 kgs. Furthermore, the engine was mounted longitudinally by using all of the trunk space as opposed to the 308’s transverse layout. This resulted in an increased wheelbase of 110mm / 4.3 inches.

Production of the 288 GTO started in mid 1984 and, having produced the required 200 units, it was officially homologated in Group B on June 1st 1985. As such, the 288 GTO is NOT a prototype but a fully fledged Group B car. However, before the racing program had started, news of the cancellation of Group B was received and the car would never compete. Ferrari did produce an extra 73 units (one of which was used to build the first Evoluzione version) up until 1987 when it was officially replaced by the now legendary F40.

“EVOLUZIONE” PROTOTYPE VERSION

Ferrari 288 GTO “Evoluzione” Prototype

After building the required 200 homologation units, Ferrari went on, with the help of long time partners Michelotto and Pininfarina, to start conception / production of the 20 “evolution” cars for competition. Ferrari, since it was part of the FIAT group, had no official rallying ambitions (that focus was with Lancia) but still intended the 288 GTO to be run predominantly in tarmac events of the World Rally, European, and Italian Championships by privateer teams (as it did with the 308). The Evoluzione would also have competed in Group B circuit racing but that series never really took off.

The Evoluzione sported advanced lightweight aerodynamic bodywork features that netted a dry weight of only 940 kgs. The engine was also improved and the boost on the turbochargers cranked up a notch. A combination that could provide up to 650 HP, therefore cutting in half the power to weight ratio of the road car. A feat in every aspect.

However, as history would unfold, Group B was soon to be cancelled thus production of the racing cars ended with 6 prototype units already built (one derived from a road car and the 5 others from scratch). This exercise was not futile for Ferrari though as many of the 288 GTO Evoluzione’s features were carried over to the iconic F40.
