Ferrari did, however, win the Constructors' Championship. The same year, the Formula One works moved partially out of the original Maranello factory into its own autonomous facility, still in Maranello but directly next to the Fiorano test circuit. Four wins by René Arnoux and Patrick Tambay won the team another constructors' title in 1983, but neither driver was consistent enough to challenge for the drivers' title. Patrick Tambay took an especially emotional victory at San Marino in front of the Tifosi, but left to join the Renault team at the end of the season. Michele Alboreto was hired for following his impressive performances during the previous year driving a Cosworth-powered Tyrrell. He won the , but the team's performance was not competitive enough to challenge the TAG-Porsche-powered McLarens of Niki Lauda and Alain Prost. In the following year, however, Alboreto was Prost's closest challenger for the championship, leading it at one stage before the team's competitiveness slumped in the final races. Arnoux, meanwhile, fell out with the team and was replaced by Stefan Johansson after the first race of the season. continued the disappointing trend of the previous season as neither Alboreto nor Johansson could win a race, and never looked like doing so. For , Johansson moved to McLaren and was replaced by Gerhard Berger, who got the better of Alboreto as the season progressed and won the final two races of the championship as the car's form improved towards the end of the season. The team remained competitive into , finishing second in the Constructors' Championship, but a long way behind McLaren, who now used the works Honda engines which had won the previous two Constructors' Championships. The season also witnessed the end of Enzo Ferrari's ownership of the team. On 14 August 1988, Ferrari died at the age of 90. Fiat's share of the company was raised to 90% with Enzo's only remaining son, Piero Ferrari, inheriting the remaining share from his father. Just under a month after Enzo's death, Berger and Alboreto completed a historic 1–2 at the , the only time a team other than McLaren-Honda won a Grand Prix in the 1988 season. Berger dedicated the win to the late Enzo Ferrari. Then triple world champion Alain Prost left McLaren to partner Mansell at Ferrari for the 1990 Formula One season. As reigning world champion, Prost assumed the role of lead driver, much to teammate Mansell's dismay.
