From the Mega 8000 series, the favorite became the 8400, which was especially popular as a contract machine. After the introduction of the 8050 series, the 8400 was kept in production but received a few updates. The lifting capacity was increased to 7 tons. However, the engine represented an older generation compared to the equally powerful 8450. Autocontrol was updated to version 2.1, which included a so-called forced descent function. One of the secrets to the 8400’s popularity was the traffic tractor version, which with its 50 km/h speed, competitors still could not offer in the mid-1990s.
In the spring of 2000, the engine was replaced with a newer version. Power increased to 150 horsepower, partly thanks to new nozzles, and torque rose by as much as 105 Nm. The torque increase was 31% instead of the previous 16%. Standard equipment now included, among other things, a sturdier industrial front axle, larger tires, and longer lift arms.
In the spring of 2002, power was further increased to 160 horsepower and standard equipment included millimeter tires. The engine now featured a viscous fan. The 8400 was also available as a long wheelbase version. The 8400 was only discontinued after the introduction of the T Classic models.
