This 4x4 Lego Technic includes many mechanical components close to reality. The 3 motors are used to control the 4 wheels and the direction (1 motor per axle with 2 wheels and 1 motor for the direction that also acts on all 4 wheels). This 4x4 does not roll very fast but really climbs through these big wheels "low pressure" and these suspensions with a big deflection. Certainly the price is quite high but with very good prices Amazon, it becomes very acceptable.
