CNG buses are a common sight in many European cities. Iveco has announced that they have already sold 3,900 units of its Irisbus CNG powertrains. The latest important buyers have been the cities of Madrid (which recently bought 60 units, for a total of 350), Seville (30 units, for a total of 80) and Burgos (2 to reach 12 units) in Spain.
These buses run along the existing diesel (and biodiesel) counterparts in regular urban and suburban lines. The units, which are 12 meters long (about 37 feet) are equipped with Iveco's Cursor 8 engine, which is a 7.8 liter unit good for 200 HP and 1100 Nm of torque (about 1500 lb ft).
The engine complies the current Euro IV rules for pollution with 0.53 g of NOx / kWh. The future Euro VI regulations will likely require buses to have this level of about 0.5 g/kWh.
