The BT45 was the fourth car designed by Gordon Murray for the Brabham F1 team headed by one Bernie Ecclestone. It was powered by a 500bhp 3-litre flat-12 engine from Alfa Romeo.

The car didn’t manage the success that Brabham would later become used to, only scoring nine points over the year from three fourth-place finishes. 

The main point of interest with the Brabham BT45 is that it was the first car the team raced with its iconic Martini livery, body painted a deep red and those elegant blue lines flowing back over the body. Here was a look that encapsulated the 1970s and defined an era for the Brabham team.
