The invention relates to an autonomously driving, two-lane vehicle with a front drive module (7), viewed in the vehicle longitudinal direction (x), at least one central transport module (9) and a rear drive module (11), the front drive module (7) having a front axle Has a drive for driving the front vehicle wheels (1) and an associated front-axle energy store, and the rear drive module (11) has a rear-axle drive for driving the rear vehicle wheels (3) and an associated rear-axle energy store, and the middle transport module ( 9) is spaced a high distance (Δz) from the roadway (1) when driving. According to the invention, in order to lower the transport module (9) onto the roadway (19), the front drive module (7) and the rear drive module (11) are articulated to one another directly or indirectly via at least one articulated connection (19, 21; 31), the articulated axis (G) of which is aligned in the vehicle transverse direction (y). The lowering process of the transport module (9) into a lowering position takes place through a rotating and / or tilting movement about the joint axis (G).
