The Alexander Dennis Enviro 300

The Alexander Dennis Enviro 300 (previously known as the TransBus Enviro 300) is a light-weight single-deck bus built by Alexander Dennis (previously by its predecessor TransBus International) in the UK since 2001. The design was introduced in order to fill a gap in the manufacturers product range and was the first bus to be built as an integral bus by the manufacturer.

The Enviro 300 was the first of the new Enviro range of buses from TransBus. The Cummins ISBe220 engine is provided as standard, with the choice of 3 gearboxes: ZF 5HP502, Allison T280R and Voith DIWA854.3E.

It was developed to compete with the European-built heavy-weight single-decker buses sold in the UK, the most notable being Volvo. Most full-size (12m or more) single-decker buses are designed for use on the continent and to carry a large number of standing passengers, but the Enviro 300 is designed solely for the UK market, where large numbers of standing passengers are not often carried. TransBus therefore believed that operators could make significant fuel savings by operating light-weight buses.

The Enviro 300 has not sold as well as the manufacturer had hoped, though sales have not been helped by the collapse of TransBus International in 2004. However large numbers are now entering service with the First Group, largely for operation in Worcestershire, and a small number have entered service with the Stagecoach Group.

After few years since its launch, the chassis of the Enviro 300 became available with East Lancs Esteem bodywork, with the first two for Courtney Coaches entered service in 2006. This is the first time the Enviro 300 chassis being constructed with bodywork by another manufacturer.

The Enviro 300 body will be available on MAN 18.240 chassis later in 2007. As part of the 2007/8 order, Stagecoach have announced they have ordered 100 of this combination. 95 are to be standard 12m buses and the other 5 being 12.8m long.
