The Alexander Dennis Enviro400 is a twin-axle low-floor double-decker bus that was built by the British bus manufacturer Alexander Dennis between 2005 and 2018. It replaced the Alexander ALX400 (from which the Enviro400 was developed). In 2014, the Enviro400 was succeeded by the updated Alexander Dennis Enviro400 MMC and production of the classic Enviro400 ceased in 2018.
The Enviro400 is available both as an integral bus and as a standalone bodywork and chassis. The Enviro400 chassis replaced the Dennis Trident 2 (and continued to be badged as the Trident for a time) and was formerly available with East Lancs Myllennium Lolyne and Optare Olympus bodywork; the Enviro400 body replaced the Alexander ALX400 designs and was sold on Scania N230UD and Volvo B9TL chassis.[4]
The engine of the integral Enviro400 is a six-cylinder Cummins driving through a Voith or ZF automatic transmission, although a MAN D0836 engine began to be offered from 2007. A hybrid-electric version of the powertrain developed by BAE Systems was also available.[1]
