In November 1999, Scania presented a new range of Euro III compliant truck engines, which soon became available on the buses too. The DSC9 and the DSC12 were renamed DC9 and DC12, and new power outputs were 230 hp (1100 Nm), 260 hp (1250 Nm) and 300 hp (1400 Nm) for the DC9 and 420 hp (2000 Nm) for the DC12. To fill the gap between them, they were joined by the new 10.6-litre (10641 cc) DC11 engine with power outputs at 340 hp (1600 Nm) and 380 hp (1800 Nm).
