Motor Racing Developments initially concentrated on making money by building cars for sale to customers in lower formulae, so the new car for the Formula One team was not ready until partway through the 1962 Formula One season. The Brabham Racing Organisation (BRO) started the year fielding a customer Lotus chassis, which was delivered at 3:00 am in order to keep it a secret. Brabham took two points finishes in Lotuses, before the turquoise-liveried Brabham BT3 car made its debut at the 1962 German Grand Prix. It retired with a throttle problem after 9 of the 15 laps, but went on to take a pair of fourth places at the end of the season.
