Drive unite for a motor vehicle

A drive unit for a motor vehicle having an all-wheel drive, the motor vehicle having a first wheel axle and a second wheel axle, comprising:

• an internal-combustion engine with a crankshaft system arranged between the first wheel axle and the second wheel axle, the crankshaft system having at least one horizontally oriented crankshaft, wherein at least one piston of the internal-combustion engine causes rotation of the crankshaft;
• a continuously variable transmission system acted upon by the crankshaft, the transmission system driving wheels of the first wheel axle and the second wheel axle;
• a first set of V-pulleys of the transmission system interacting with the crankshaft, wherein the first set of V-pulleys is connected with a first differential of the first wheel axle via a first drive shaft;
• and
• a second set of V-pulleys operatively connected with the first set of V-pulleys via an endless member, wherein the second set of V-pulleys influences, with an interposition of a second drive shaft, a second differential of the second wheel axle, wherein
• the crankshaft system of the internal-combustion engine comprises two parallel crankshafts, which are influenced by the at least one piston, which crankshafts interact by way of synchronization gears and rotate in opposite directions, wherein
• an output of the crankshaft system takes place toward the first set of V-pulleys from a first end region of the crankshaft system, and
• in a second end region of the crankshaft system, the crankshafts are equipped with flywheels.
