Scania N series

The Scania N series is a line of low-floor bus chassis with a straight-up, transversely mounted engine at the rear that Scania has built since 2006 as the replacement for the N94. It is sold as the N UB two-axle single-decker, the N UA tri-axle articulated bus and the N UD two-axle double-decker, the last mainly built for the United Kingdom, where it was first available both as the integral Scania OmniCity and as a separate chassis with Alexander Dennis Enviro400 bodywork. The N230UD is the best-selling variant, with Stagecoach the largest customer, and the N250UD succeeded it as the main model in 2015. A gas-powered N280UD double-decker was launched in 2016, with Reading Buses as its first customer.
