The Volvo FL is a series of trucks manufactured by Volvo Trucks. It was introduced in 1985 and has remained in production ever since, in a variety of different models of different weight ratings. It has been used in a variety of different roles aside from a truck, including as a fire engine.

"FL" stands for "Forward Control" and "Low-level Cab". The FL6 and the larger FL7 and FL10 appeared in the summer of 1985. In 1986 the smaller FL4 also appeared, with a 4-litre TD41 turbodiesel engine. The model originated after Volvo had lost much of its global market share in the medium weight segment by the 1970s, prompting the development of an entirely new model to replace the previous Volvo F series.

Beginning in 1995 some of the FL6 models were equipped with the D6A250 engine, which utilized a turbocharger as well as a supercharger. This allowed for an unusually high power-to-weight ratio and plentiful low-end torque. Volvo's larger D7A engine, as fitted to the FL7, could have been easily made to produce the same power but was considerably heavier as it was the same size as the larger ten-litre D10.

The FL4 and FL6 have a cabin 2.3 m (7.5 ft) wide, to allow for city use. The FL7 and FL10's cabins are 2.5 m (8.2 ft) wide. The heavier FL7 and FL10 was available in a variety of configurations, ranging from 4x2 to 8x6. In 1997 the Volvo FLC arrived, a lighter model rated for 7.5 tonnes (16,500 lb) rather than the 10 t (22,000 lb) of the regular FL. The FLC has Volvo's D4A 3989 cc turbodiesel with 135 PS (99 kW), a five-speed manual, and an air sprung rear axle.

For North America, a version called the FE6 was introduced in 1986. There was also a heavier duty seven-litre version called the FE7 - this combines the narrow FL6 cabin with the engine of the FL7. Aside from Volvo's own engines, Caterpillar's 6.6 litre 3116 engine was also offered at a lower price. In 1990 the FE6/FE7 was gradually replaced by the FE42. This sturdy model used the Swedish-built FL/FE cab placed atop the chassis of the 1988 medium bonneted Volvo WG range. The name stood for "Forward control", "Economy", 4x2 configuration. Later the 6x4 FE64 was added to the lineup. In the mid-nineties sales of the FE42/64 series began shrinking as American truck buyers gradually changed back to conventional models. A tractor version was called the FE42T. The last model year for the American range was 1998.

For customers needing a compact truck with high maximum loads, the FS7 was presented in 1987. Very similar in execution to the US market FE7, it combined the FL6 cabin and chassis with the bigger 7-litre TD73 engine from the FL7. The FS7 was mainly intended for inner-city distribution roles and was manufactured until 1996, when the more powerful and even lighter FL6 Supercharged made the FS7 redundant.

In 2000 the FL series received a facelift, which included a new front clip. The doors and cab structure remained mostly the same.

The Volvo FL6 is powered by a Volvo D6B 180-250 hp, six-cylinder turbocharged and intercooled diesel engine. The control system had a major update, with Volvo's TEA electronics architecture to bring it to line with the rest of its bigger cousins. Inline fuel injection pump was replaced with the EDC rotary distributor pump from Bosch with the identical horsepower; despite the loss of supercharger from the previous D6A engine. The cruise control, automatic exhaust brake and accelerator now became the so-called fly by wire as standard. Full integration with the rest of the vehicle system such as Electronic Suspension Control and ABS made it much more efficient and user friendly.
