In the mid-eighties, DAF unveiled their ATi (Advanced Turbo Intercooling) range of revised big diesels and a new flagship, the F3600 Turbo Intercooling. The 3600 was the pinnacle of all heavy DAF models with the F241 tilt cab, originally introduced in 1973 on the F2800-series.

This cabover tractor from the second half of the eighties with a 6×4 drivetrain -an FTT in DAF terminology- has the F241 sleeper cab. The letter F stands for ‘Frontstuur’ (forward control) and the number 241 refers to the cab width in centimeters, which is equal to 94.9”. In a nutshell, it was the widened version of the 1969 F218 tilt cab.

Around 1985, the other F241 options were a day cab, the Space Cab (a sleeper cab with a raised roof), and the top sleeper cab (literally based on the day cab).

DAF DKZ 1160 engine, turbocharged and intercooled

The 3600 was powered by the truck maker’s DKZ 1160 turbocharged and intercooled diesel engine, an inline-six with a displacement of 11.6 liter and a maximum power output of 373 DIN-hp. At that point, DAF’s most powerful truck diesel ever. As an aside, the daddy of all 11.6 liter DAF diesels was the Leyland O.680.

ZF Ecosplit 16-speed transmission, double-H shifting pattern

In Europe, the standard transmission offered in the F3600 and other contemporary heavy-duty DAFs was the ZF Ecosplit 16-speed, a synchronized transmission with a double-H shifting pattern. ‘Eco’ as in economical, rather than eco-friendly.

A stout chassis setup with a pair of then-new DAF 1355 planetary drive axles. The tractor must have been used for a tough job, like logging or heavy haulage. For dedicated long-distance road transport, no European hauler would have opted for such a beasty and beefy 6×4 configuration.

I must say this is a very accurate and realistic cutaway of a DAF 1355T tandem with its planetary drive axles, leaf springs, and eight torque rods (so four per axle). The tandem’s factory axle weight rating was 26 tonnes (57,320 lbs), some serious business right there.

Another fine example of the F3600-series, I spotted this 1986 6×2 box truck at the ‘Heart for DAF Days’ in Eindhoven, held in October 2024.

From 1987 onwards, the F2800/3300/3600 trucks and tractors were gradually superseded by the F95-series with the all-new F249 cab. The rather generic looking tilt cab was the result of the Cabtec joint venture between DAF and ENASA from Spain, at that time the owner of Pegaso and Seddon Atkinson. The ENASA variants were used on the Pegaso Troner and Seddon Atkinson Strato.

The production run of the F2800/3300/3600 came to an end in 1990, but the good ol’ F241 cab soldiered on for a few more years. For one last time, it got an updated front and interior, to be offered as a cheaper alternative to the F95. On the European market, the model designations on the cab’s final edition were 2900 and 3200.

On a related note, it’s all too obvious that the illustrious 2600-series, introduced in 1962, was the forefather of all first-gen DAF vehicles with a tilt cab: the 1969 F218, the short-lived 1972 F198, and the 1973 F241.

Now I could listen to this orchestra endlessly, what we hear is the unmistakable roar of a classic big-DAF-diesel. The owner is taking his 1987 DAF FTG 3600 DKZ (a 6×2/4 tractor) out for a spin. Encore, maestro!
