The DAF 600 was a small car that DAF manufactured in Eindhoven ( Netherlands ) between 1959 and 1963. It was the manufacturer's first car and was presented at the Amsterdam Motor Show in February 1958 . In 1957 DAF had already published the first details. The car had an air-cooled two-cylinder four-stroke piston engine with 590 cc capacity and a power of 20 HP (15 kW) at 4000 min -1 . The engine was in the front, the gearbox on the rear axle. The car reached a top speed of 90 km / h.

Like all DAFs based on this model, the DAF 600 was equipped with a centrifugal clutch and a continuously variable, V-belt-operated automatic Variomatic . The DAF Variomatic works with flyweights that are pressed outwards against springs by centrifugal forces, plus vacuum units that generate an adjustment force through the suction from the engine's intake system. The negative pressure from the engine's intake tract pushed the conical pulleys into a position with a higher gear ratio when you slowly let go of the accelerator pedal: Although the engine speed remained the same, the transmission increased the cruising speed. However, this took a long time, even if the road did not climb.

The Variomatic allowed increased engine braking force when a switch on the dashboard was pressed that reversed the effect of the vacuum boost, with a higher vacuum meaning a lower gear ratio. In a test report at the time, the drive belts did not slip even when it was wet or in heavy rain, although the Variomatic was not covered from below against the road. However, the wheels showed poor traction because the Variomatic required more effort to differentiate than with conventional differential gears. The noise level, which was high for the time, was also criticized; at 85 km / h, 90 dB was measured in the interior on the motorway and 92 dB on paved roads.

The DAF has its own reverse gear for reversing . The cars drove backwards as quickly as they did forwards, which made the remaining specimens into favorites for a long time in nonsense races driven backwards. Since the bevel drive was not synchronized, noises often occurred when shifting forwards and backwards from the neutral position, even when operated correctly.

The twelve-inch wheels were suspended individually, at the front on a wheel-guiding transverse leaf spring and damper struts with rack and pinion steering and at the rear on pendulum half-axles with coil springs and telescopic shock absorbers. There were no joints on the drive shafts, the V-belts were twisted a little to accommodate the change in angle during compression. Hydraulic drum brakes on all wheels were used to brake.
