The Alexander Dennis Enviro300 (previously known as the TransBus Enviro300) is a light-weight full-size single-decker bus that was built by Alexander Dennis (previously by its predecessor TransBus International) in the UK between 2001 and 2015. The design was the first of the new Enviro range of buses from TransBus and also the first bus to be built as an integral bus by TransBus.
The Enviro300 was introduced in order to fill a gap in the manufacturer's product range. At the beginning the Cummins ISBe220 5.9 litre Euro III engine was provided as standard, but for Euro IV and V, the engine is the 6.7-litre ISBe with 225 hp for Euro IV and 225 or 250 hp for Euro V. There is a choice of 3 gearboxes: ZF EcoLife (originally 5HP502C, then 6HP504C), Allison T280R and Voith DIWA854.5 (originally DIWA854.3E). The second generation Enviro300, with front end redesigned to match the Enviro200 and Enviro400, was launched in 2007.
Production of the Enviro300 ceased in 2015 with the introduction of a long-wheelbase Enviro200 MMC replacing the Enviro300. More than 1,000 were produced.
The TransBus Enviro300 was launched in 2001 by TransBus International, becoming the first member of the Enviro range; with the collapse of TransBus in 2004, successors Alexander Dennis took over production and rebranded the Enviro300 as the Alexander Dennis Enviro300.
A common design was used primarily that the bus has a single-curvature windscreen with a peaked roof dome and a separately mounted destination sign. The bus was developed to compete with the European-built heavy-weight single-decker buses sold in the UK, the most notable being Volvo. Many full-size (12m or more) single-decker buses are primarily designed for use on the continent and to carry a large number of standing passengers which is commonplace on the continent, but the Enviro300 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 and produced a vehicle which is claimed to be lighter than its continental rivals but offer more seating capacity.
