A multi-speed transmission with an input shaft (1) and an output shaft (2) not coaxial in relation to this, with two spur gear speeds (ST1, ST2) that are connected tightly on the input side with the input shaft (1) rotating at an input rotational speed (n) and generate two output rotational speeds (n1, n2), with a main gearset that is connected with the output shaft (2) and is constructed as a two webbed four shaft transmission with two coupled, shiftable planetary gearsets (RS1, RS2) to which the output rotational speeds (n1, n2) of the spur gear speeds (ST1, ST2) are transferable through several shifting elements (A to E) through their selective closing to the clutch of at least six forward gears and can be shifted without group shifting. Here the output rotational speed (n2) of the second ratchet speed (ST2) is transferable through a first shifting element (A) to a first free shaft of the main gearset, and through a second shifting element (B) to a second shaft of the main gearset, and the rotational speed (n1) of the first spur gear speed (ST1), and whereby the output rotational speed (n1) of the first spur gear speed (ST1) is transferable through a fifth shifting element (E) to a third shaft of the main gearset. The second shaft of the main gearset is fixable through a third shifting element (C) and the third shaft of the main gearset through a fourth shifting element (D). A fourth free shaft of the main gearset is connected with the output shaft (2). In accordance with the invention, a total of six shifting elements (A to F) are provided. The output rotational speed (n1) of the first spur gear speed (ST1) is in addition transferable through the sixth shifting element (F) to the second shaft of the main gearset, and at least eight forward gears and maximally two reverse gears are shiftable.
