Ferrari built six (five production models and one prototype) 288 GTO Evoluzione models with more aggressive and aerodynamic body styling and increased power. The Evoluzione, introduced in 1986, was built to race in Group B but when that series was cancelled the project was also shelved as it was not fit for any other racing series.
Ferrari had planned a production run of 20 cars to comply with Group B homologation requirements for Evolution models. The 288 GTO Evoluzione is powered by an upgraded version of the 2.9 L V8 used in the normal 288 GTO that has twin-turbochargers and produces 650 hp (485 kW; 659 PS) at 7,800 rpm. It has a weight of around 940 kg (2,072 lb) and can reach a top speed of 225 mph (362 km/h).
It features a unique front end designed for aerodynamics with front canards, channels and vents as well as a large carbon fibre rear spoiler and numerous large NACA ducts. Many styling and mechanical elements from the Evoluzione influenced the soon to follow F40.
