A very full and complete entry was received for the seventeenth Dutch Grand Prix held on the sandy Zandvoort circuit and it was notable for the number of brand-new Grand Prix cars that were ready for first practice; either brand-new models of existing designs, modified versions or entirely new designs. The Brabham team had four cars in all, a brand-new chassis with 1967 Repco engine and a Hewland FT200 gearbox, as used on Formula 2 cars; Brabham’s 1965 chassis that he used at Monaco, with a 1967 engine and heavyweight Hewland box, and the two 1966 Brabham-Repco V8s for Hulme.
The Scuderia Ferrari also had four cars, the long cockpit 1966 car with 1967 engine for Parkes, a 1967 car for Amon, a brand new 1967 car for Scarfiotti and one of the 1966 Italian GP cars as a spare.
Team Lotus were almost off the ground with pride, having two Lotus 49 cars with Cosworth 3-litre V8 engines, one being the car that Graham Hill had been testing in England and the other being brand-new, which Clark saw for the first time when he arrived on the morning of the first practice day.
