From Wikipedia: 'The Brabham BT44 was a Formula One racing car designed by Gordon Murray, Brabham's chief designer. An update of the partially successful BT42 of 1973, the BT44 was a simple design with a standard Ford DFV/Hewland gearbox combination, but was very clean aerodynamically. Murray had an eye for clean lines, and the BT44 was particularly graceful. He was also a forward thinker, and tinkered with side skirts and airdams on the car, a precursor to ground effects aerodynamics.
Sponsorship came from Martini. The 1974 season was successful for Brabham. Carlos Reutemann took 3 wins with the car, partnered by Carlos Pace who was able to string a series of promising results together. Brabham finished at a fighting fifth place in the Constructor's Championship after a closely fought season.'
