Overview
The Ferrari GTO (often referred to as Ferrari 288 GTO) (Type F114) is an exotic homologation of the Ferrari 308 GTB produced from 1984 until 1987 in Ferrari's Maranello factory, designated GT for Gran Turismo and O for Omologata (homologated in Italian).
Background
Contrary to what is reported historically in the press, the Ferrari GTO was not immediately born to compete in the new 1982 Group B Circuit Race series; Enzo Ferrari did not have overall control of the Road Car division, which was at the time managed by the General Director Eugenio Alzati and the FIAT MD (CEO) Vittorio Ghidella. In 1983 Mr Ferrari noted from discussions with close friends and clients that the road car sales were falling due to stronger competition from rival car makers and what he described as the "excessive gentrification" of the Ferrari model lineup.
Turbocharging: from F1 to road cars
The success of turbocharging in Formula 1 and the introduction of some new tax laws (above the 1999cc displacement threshold) had prompted Ferrari to first build the 208 Turbo and then discuss turbocharging also in 3 litre form for a road car which could produce 330 bhp. The first 208 turbo did not feature an intercooler so the performance and reliability was somewhat delicate due to high combustion temperatures. Ferrari approached the head of powertrain for the Gestione Sportiva (Racing Division), Nicola Materazzi, to give an opinion on the proposed specification for the new 3L turbo engine. Materazzi had joined from Osella in 1979 (before then at Lancia Reparto Corse) due to his experience with forced induction and had been involved in the 126 F1 car experimentation between Comprex and turbo. When Materazzi showed confidence that 400 bhp could be reliably extracted from 3000cc (133 bhp/litre), Ferrari placed his trust in him on condition that it would deliver as promised. Ferrari also jokingly suggested that Materazzi work on the 268 engine destined for the Lancia LC2 Group C racing car, due to similarities in displacement and mechanical parts.
