Alexander Dennis Models Explained

Alexander Dennis (ADL) is one of the biggest UK bus manufacturers. This guide explains common model names you’ll see in modern UK fleets.

Enviro: the big family

“Enviro” covers multiple models and generations. The number often hints at size/type.

• Enviro200 - common single deck workhorse (many variants).
• Enviro400 - very common double deck model line.
• MMC - “Major Model Change” (updated generation often written as “Enviro400 MMC”).

Integral vs body-on-chassis in ADL

Most Enviro models are treated as integral model lines in enthusiast logging (even when there are underlying chassis details).

BusOva tip

If your schema stores manufacturer/model: use “Alexander Dennis” + “Enviro400” (and add MMC if known). If unsure, upload clear photos and keep it simple.
