Williams FW13

1989

The FW13 was designed by Argentine Enrique Scalabroni and featured a distinctive oval-shaped air intake, as well as the Renault RS1 3.5-litre V10 engine, Renault's first non-turbo Formula One engine which was rated at approximately 650 bhp (485 kW; 659 PS). The car was driven by Belgian Thierry Boutsen and Italian Riccardo Patrese. It made its racing début late in the 1989 season - at the Portuguese Grand Prix - due to the team's wish to get any bugs out in testing beforehand which forced the team to use an updated version of their 1988 car dubbed the FW12C for the first 12 races of the season, by which time the FW12C had reached its development peak and both Patrese and Boutsen were eagerly awaiting the FW13. Both the drivers and the team agreed the new car was needed to challenge the likes of McLaren with their V10 Honda engines, Ferrari with their V12 engine and innovative Semi-automatic transmission, and the leading V8 powered cars, the Benetton-Fords.

After teething problems saw the Williams pair out of contention in Portugal, Patrese reverted to the old car in Spain while Boutsen continued with the new car. With the bugs finally ironed out, the new car proved very competitive in the final two races of the year, as Patrese and Boutsen finished second and third respectively at Suzuka (though helped by the infamous McLaren collision at the chicane which took out Alain Prost and later saw Ayrton Senna disqualified). The Belgian then won the final race of the year in Australia after a brilliant drive in very wet conditions, with Patrese third. These results enabled Williams to leapfrog Ferrari into second in the Constructors' Championship while Patrese had his best ever year by finishing third in the Driver' Championship behind the McLarens.

BBC television commentator Murray Walker reported during the Australian GP that the FW13, like its predecessor, was originally designed to use the computer-controlled active suspension rather than the conventional suspension used on most cars at the time. However, after the problems encountered in the first half of 1988 with the FW12, Williams decided more work was needed on getting the active suspension to work better with the naturally aspirated engines of the time and converted the new car to passive suspension. Walker reported that this was the reason the FW13 had so late in making its race debut as the team worked hard in testing to get the handling of the car right before putting it into competition.

1990

For the 1990 season, the car was updated, becoming the FW13B. It featured revised sidepods and suspension upgrades, as well as Renault's RS2 3.5-litre V10 engine. The FW13B proved fast and reliable, with Patrese and Boutsen winning one race each – Patrese at "home" in San Marino (the San Marino Grand Prix was actually run at the Imola Circuit in Italy as the small Republic of San Marino did not have enough land for a race circuit), and Boutsen in Hungary after also claiming pole position. In the latter race, Patrese completed an all-Williams front row, drove the fastest race lap and finished fourth, giving the team plenty to celebrate that weekend. However, the team fell to fourth in the Constructors' Championship, behind Ferrari (with whom Alain Prost challenged for the Drivers' Championship) and Benetton (which won the final two races of the season thanks to former Williams driver Nelson Piquet).

The general feeling around the F1 paddock was that the FW13B was the fastest car on the grid in 1990 and that the only thing holding it back from challenging McLaren and Ferrari more often was Williams not having a true number 1 driver, as both Boutsen and Patrese (particularly Boutsen) were seen as journeymen drivers. After French World Champion Alain Prost had announced he would be leaving McLaren at the end of 1989, he began talks with both Ferrari and Williams about driving for them in 1990. Frank Williams was hopeful of signing Prost (who ultimately chose Ferrari) and many including outspoken 1976 World Champion James Hunt felt that had Prost driven the FW13B in 1990 instead of either Boutsen or Patrese then the true potential of the car could have been reached.

The FW13B was replaced for the 1991 season by the successful FW14.
