1. A supercharged V8 internal combustion engine (10) having two cylinder banks (11, 12) with four cylinders (1-4, 5-8) arranged in each of its two cylinder banks (11, 12), the V8 engine having an ignition sequence of 1-5-4-2-6-3-7-8 with a 90° ignition offset between cylinders so that in each cylinder bank, two cylinders (2 and 4 in bank 11 and 7 and 8 in bank 12) have the 90° ignition spacing, an intake line (13, 14) for feeding combustion air to the two cylinder banks. (11, 12) of the internal combustion engine (10), two exhaust gas collection lines (15, 16) for conducting exhaust gases away from the cylinders (1-8) of the cylinder banks (11, 12), an exhaust gas turbocharger (17, 18) including a turbine (19, 20) arranged in each exhaust gas collection line (15, 16) and a compressor (21, 22) arranged in each intake line (13, 14, one of the two cylinders with 90° ignition spacing in each bank (11, 12) having a separate exhaust gas line (23, 24) extending from the respective one cylinder (4 and 8) of the cylinder bank (11, 12) and joining the exhaust gas collection line (15, 16) downstream of the turbine (19, 20) of the exhaust gas turbocharger (17, 18), and the other cylinders (1, 2, 3, 5, 6, 7) being connected to the exhaust gas collection line (15, 16) upstream of the respective exhaust gas turbine (19, 20), each of the exhaust gas collection lines (15, 16) comprising a first common exhaust gas manifold (25) for all the cylinders (1-3, 5-7) which are combined in the respective exhaust gas collection line (15, 16), and an exhaust gas turbocharger housing (26), which is integrated into the exhaust gas manifold (25), the separate exhaust gas lines (23, 24) having second exhaust gas manifolds (27) for the cylinders (4, 8) of the two cylinder banks (11, 12), and a connection piece (28) for each of the exhaust gas collection lines (15, 16), each of the exhaust gas collection lines (15, 16) having a first flange (29) downstream of the turbine (19, 20), the second exhaust gas manifold (27) and the connection piece (28) at each bank (11, 12) being single piece components, and the connection piece (28) having a second flange (30) for connection to the first flange (29).
