• a second axle having two second drive wheels (3);
• a passenger compartment (5);
• an internal combustion engine (4), which is provided with a plurality of cylinders (8), where respective pistons (9) slide on the inside, and with a drive shaft (10) connected to the pistons (9) and oriented longitudinally, namely parallel to a driving direction of the car (1);
• a transmission shaft (25), which is oriented longitudinally and is configured to transmit the motion from the internal combustion engine (4) to the first wheels (2);
• a gearbox (16) provided with at least one primary shaft (18), which receives the motion from the drive shaft (10), and with at least one secondary shaft (19);
• a first epicyclic differential (22), which receives the motion from the secondary shaft (19) of the gearbox (16) and transmits the motion to the first wheels (2) through the transmission shaft (25) and to the second wheels (3);
• and
• a second epicyclic differential (23), which is coaxial to the two second wheels (3), is interposed between the first epicyclic differential (22) and the second wheels (3), receives the motion from the first epicyclic differential (22) and transmits the motion to the second wheels (3);
• wherein the two differentials (22, 23) are coaxial to one another and are arranged side by side.
