Already in service on a local route, the 9.5m-long vehicle is powered by a 160bhp Cummins engine, with four-speed Voith gearbox.
The 37-seater has seatbelts throughout, along with a CCTV system.
Thanks to the manufacturer's Micro Hybrid technology, excess energy generated by the braking system is redistributed to power the pneumatics, hydraulics and electrical systems.
"The Micro Hybrid system offers us a potential 10% reduction in fuel consumption and savings on an anticipated 15-year operational service life, and this therefore played an important part in our selection of this new StreetLite for our fleet," says Neil Docherty, managing director of Docherty's.
The new bus has been in operation for several weeks and, he adds, is proving popular with the drivers, who particularly like the increased visibility they have in the Streetlite.
"So far we are very pleased with the fuel consumption and overall operational performance – our drivers like driving it and our passengers enjoying riding in it."
