A double-decker bus or double-deck bus is a bus that has two storeys or decks. Double-deckers are primarily for commuter transport, but open-top models are used as sight-seeing buses for tourists, and there are coaches too for long-distance travel. They appear in many places around the world but are presently most commonly used as mass transport in cities of Britain, in Ireland, in Hong Kong, and in Singapore.

The first prototypes were built in 1992, but mass production started in 1993, only a year after the high-floor B10B. It was popular in Australia, Scandinavia and the United Kingdom. It had the engine mounted on the rear overhang of the bus. It became the successor of the city bus version of the B10B and was used as a base for single-decker buses worldwide. The B10BLE was available in diesel powered format, and later in a compressed natural gas powered format with the fuel tanks on the roof of the bus. Its low-floor design was widely promoted by Volvo when it was first launched, on the basis of added convenience to the passengers, and the increase in transport efficiency due to the low-floor design.

Volvo B13R is a 12.8-litre engined coach chassis available as both two- and tri-axle from Volvo since 2009. It was the first of the Volvo BXXR series, replacing the higher output configurations of the B12B. It was later joined by the B11R, which has the same base chassis but a smaller engine. However, because Volvo decided not to upgrade the D13 engine to comply with the Euro 6 emission requirements, it was replaced by the B11R in the European market, but is still available at other markets, like Mexico. The B13R is easy recognisable as being the only modern Volvo coach chassis with air intakes on the right-hand side.
The Volvo B11R is a 10.8-litre engined coach chassis available as both two- and tri-axle from Volvo since 2011. It was introduced as the second of the Volvo BXXR series, replacing the rest of the B12B range in 2011, and later its fellow BXXR platform model, the B13R in 2013.

Later, CNG was only available on the 7500.
