Source-derived summary

The Williams FW11 is a Formula One car designed by Frank Dernie for the Williams team. The original FW11 was used in the 1986 Formula One World Championship while an updated version, the FW11B, was used in the 1987 Championship. In both years, the car was powered by a Honda 1.5-litre turbocharged V6 engine, and driven by Briton Nigel Mansell and Brazilian Nelson Piquet.

The original FW11 won nine races of the 1986 Championship, with both Mansell and Piquet challenging for the Drivers' title before dramatically losing out to Alain Prost in his McLaren in the final race of the season in Australia. The FW11B won nine races of the 1987 Championship, and Piquet won the Drivers' title despite winning fewer races than Mansell. In both years, Williams comfortably won the Constructors' title.

The FW11B was the last Williams car with a turbocharged engine until the FW36 in 2014.

History

1986

In 1986, the car won first time out in Brazil with Piquet, before Mansell laid down a title challenge with four wins. Williams were shaken by the near fatal road crash of Frank Williams which demoralised the team. Williams survived the crash but became a quadriplegic as a result, with the 1986 British Grand Prix the first time during the season he would appear in the Williams pits as he went through his rehabilitation.

Editorial analysis

Why this record matters

The phrase “formula One racing car” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Aug 24, 2026. The linked authority identifier is Q2669482. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1986, 1987 and 2014.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
