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 and its predecessor TransBus International 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 (1.6 US gal) Euro III engine was provided as standard, but for Euro IV and V, the engine was the 6.7-litre (1.8 US gal) ISBe with 225 hp (168 kW) for Euro IV and 225 or 250 hp (168 or 186 kW) for Euro V. There was a choice of 3 gearboxes: ZF Ecomat (originally 5HP502C, then 6HP504C), Allison T280R and Voith DIWA 854.5 (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.
