 In 1938, a later version of the Trado 3 conversion added drive to the front wheels and so converted a 6×4 vehicle to 6×6 drive.Unlike most all-wheel-drive vehicles, the front axle was no longer a live beam axle with added articulation for steering, but used two separate drive shafts, one to each front hub.This principle of divided drive already being established for the front of the Trado, it was a minor step for van Doorne to divide the drive to the rear wheels as well.
