Method to control a series hybrid car and corresponding series hybrid car

A method to control a car (1) comprising:

• a frame (2), which develops along a longitudinal direction (L) having a front-rear orientation;
• at least two drive wheels (4);
• at least one electric motor (6) connected to the two drive wheels (4);
• a first generation assembly (7) comprising a first electric generator (9) and a first internal combustion engine (8) provided with a first drive shaft (11), which is mechanically connected only to the first electric generator (9) and, therefore, is mechanically independent of the drive wheels (4);
• and
• a second generation assembly (7) comprising a second electric generator (9), which is mechanically independent of the first electric generator (9), and a second internal combustion engine (8) provided with a second drive shaft (11), which is mechanically connected only to the second electric generator (9) and, therefore, is mechanically independent of the drive wheels (4);
• wherein the two internal combustion engines (8) have the same number of cylinders (14);
• the control method comprises the steps of controlling, at least for part of an overall operating time, the two internal combustion engines (8) in an asynchronous manner so as to cause the two internal combustion engines (8) to rotate at different rotation speeds (WE) in order to obtain an irregular sound generation.
