The bore, on the other hand, has remained unchanged at 84 mm. The total displacement therefore rises from 3498 to exactly 3600 cm³. The performance values also undergo an increase: the maximum power goes from 245 to 272 HP at 6200 rpm, while the maximum torque rises from 320 to 360 Nm, available however at 3700 rpm instead of 3200. This engine has been mounted only onBMW 735i / 735Li E65 / 66 ( 2002 - 05 ).N62B40
