It's been five years since bus manufacturer Alexander Dennis Limited (ADL) unveiled their eye-catching double deck variant, the Enviro400 City!
The body design of the Enviro400 City is based on the New Routemaster (NRM), designed by Heatherwick Studio and manufactured by Wrightbus. Thomas Heatherwick, the founder of Heatherwick Studio, praised the Enviro400 City as a "back-to-front compliment".
