A vehicle comprising:
- a prime mover;
- a pair of right and left wheels;
- a transmission including at least a high gear and a low gear, and that transmits a driving force of the prime mover to the pair of right and left wheels;
- a clutch provided in a power transmission path between the prime mover and the pair of right and left wheels;
- and
- a controller configured or programmed to execute a moving start control to increase the driving force of the prime mover during a moving start of the vehicle to be greater than that in a normal mode in which the moving start control is not executed by controlling an engaging force of the clutch;
