Stagecoach UK Bus has placed a £7.3 million order for its first Euro 6 Optare Solo vehicles.
The order follows an earlier deal with Optare, which sees five fully electric vehicles joining the express and local bus service operator's fleet this month.
Sam Greer, Stagecoach UK Bus regional director, says: "Optare Solos have been a tried and tested part of our fleet going back a number of years, and our customer feedback suggests that our passengers like these vehicles, too."
