Brabham BT19
Formula One racing car

The Brabham BT19 is a Formula One racing car designed by Ron Tauranac for the British Brabham team. The BT19 competed in the 1966 and 1967 Formula One World Championships and was used by Australian driver Jack Brabham to win his third World Championship in 1966. The BT19, which Brabham referred to as his "Old Nail", was the first car bearing its driver's name to win a World Championship race.
The car was initially conceived in 1965 for a 1.5-litre (92-cubic inch) Coventry Climax engine, but never raced in this form. For the 1966 Formula One season the Fédération Internationale de l'Automobile (FIA) doubled the limit on engine capacity to 3 litres (183 cu in). Australian company Repco developed a new V8 engine for Brabham's use in 1966, but a disagreement between Brabham and Tauranac over the latter's role in the racing team left no time to develop a new car to handle it. Instead, the existing BT19 chassis was modified for the job.
Only one BT19 was built. It was bought by Repco in 2004 and put on display in the National Sports Museum in Melbourne, Australia, in 2008. It is often demonstrated at motorsport events.

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.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 24, 2026. The linked authority identifier is Q173757. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1966, 1967, 1965 and 2004.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. 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.
