CNG buses now form 25% of UNAUTO’s bus fleet
The municipal transport company of the city of Toledo, UNAUTO, has put 10 new natural gas/biomethane powered urban buses into service, says NGVA Europe. All vehicles are ex factory CNG versions of IVECO’s Irisbus Cityclass line. The purchase of low-pollutant buses is in part driven by the historic city of Toledo’s commitment to the environment, with CNG buses now forming 25% of its fleet. The new NG vehicles are operating in the hilly and historic city center of Toledo (see picture) and help reducing noise and pollution significantly.
All vehicles are filled at a depot where the NG/biomethane compression installation was provided by EPM Gas technology (Barcelona, Spain). The filling station can serve all ten vehicles at the same time in less than 2 hours, but also includes a quick-fill CNG compressor where a bus can be refilled in less than 10 minutes. The total contract volume for the compression system installation and the acquisition of the IVECO buses is 3.15 million Euros (USD 4.57m).
Each bus carries 8 x 162 litre cylinders made of steel reinforced carbon fiber, placed on the roof. The Cityclass bus is powered by an Iveco Cursor 8 Turbo-Intercooling engine, developing 272 hp (200kW) at 2,000 r.p.m.
