The Minardi M189 was a Formula One car, designed for Minardi by Nigel Cowperthwaite for use in the 1989 FIA Formula One World Championship. Introduced partway through the year and driven by Pierluigi Martini and Luis Perez-Sala, it scored several points finishes for the team. Updated as the M189B for the 1990 season, it was used for the first two races of the year before being replaced by the Minardi M190.

The Minardi M189 was designed by Nigel Cowperthwaite. Running on Pirelli tyres, it was powered by a Ford Cosworth DFZ V8, the same type of engine that had been used the previous season in the Minardi M188.

The Minardi M189 made its first appearance partway through the 1989 Formula One season at the Mexican Grand Prix, where it was driven by Pierluigi Martini and Luis Perez-Sala, both of whom had driven for the team the previous year. Martini qualified in 22nd but retired from the race with engine problems. Sala failed to qualify for the race, and this proved to be an ongoing problem for the Spaniard. He failed to qualify for three more races.

After making the car's debut in Mexico, Martini failed to complete the next three races but at the British Grand Prix not only finished, but scored two points for placing fifth. Sala backed this up with sixth at the same race, which was his best finish of the year. Martini finished fifth again in Portugal, where he had qualified fifth on the grid, and sixth (from third on the grid) in Australia.

Minardi finished the year with six points for 11th in the Constructor's Championship, while Martini was equal 14th, alongside Johnny Herbert, in the Driver's Championship with five points.

When the 1990 season began, Minardi's new car was still being completed so the M189 was updated to an M189B spec and pressed into service for the first two races of the year. Martini qualified on the front row for the United States Grand Prix but went on to finish seventh. He placed ninth in the following race in Brazil, the car's last grand prix before the Minardi M190 was introduced at San Marino.

The Minardi PS01 (unofficially known as European Minardi PS01) was the car with which the Minardi team competed in the 2001 Formula One World Championship. It was initially driven by Brazilian Tarso Marques, who returned to the team after last driving an F1 car in 1997, and Fernando Alonso, a Spanish rookie who had graduated from Formula 3000 and was in a long-term contract to Flavio Briatore's driver management scheme.

The PS01 marked a new beginning for Minardi. The chassis designation referred to the fact that it was the first car to be raced under the ownership of Paul Stoddart, who had bought the team from the terminally-ill Gabriele Rumi only two months before the first race of the season. In between, the PS01 was hurriedly built, with Marques' car still being assembled at the Australian GP. The car was a tidy, efficient design by Gustav Brunner, but it was hamstrung by a lack of testing and horsepower from an elderly engine (which was badged "European", after Stoddart's aviation company).

Despite this lack of preparation, the cars were surprisingly competitive, with Marques only failing to qualify once and future champion Alonso able to compete in the lower reaches of the midfield. However, the team scored no points and were hit hard when Brunner defected to the fledgling Toyota F1 team mid-season. As the season drew to a close, the frustrated Marques agreed to leave the team, allowing the well-funded Alex Yoong to become Malaysia's first F1 driver.

The team also raced an updated car, featuring a revised rear end and gearbox, from the Belgian GP onwards. This chassis was designated as the Minardi PS01B. Marques first used the B-spec version already in the Hungarian GP.

The team were unclassified in the Constructors' Championship, with no points.
