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. After launch in 2009 it soon became the default choice of chassis for Volvo's 9700 and 9900 coaches, as only the 340 hp configuration of the B12B was compatible with the Euro V requirements. The lowest configuration of the 9700; the 9700S, was not compatible with the B13R, as the engine was so tall that it would conflict with the internal floor. Over 190 were sold in the United Kingdom, with Park's of Hamilton purchasing 32. Australian interstate operator Greyhound Australia purchased 30. The tri-axle version of the B13R is known in the UK as the B13RT. Volvo later reintroduced the B13R chassis, on 30 June 2022, featuring Euro VI-compliant D13K engines. It is also part of the refreshed fourth-generation Volvo 9700 and 9900 coaches in European markets (replacing B11R) and Volvo 9800 coach in Mexico (replacing previous B13R model) and, like their predecessors, is also available in "LE" configurations for double-decker coaches.
