The Volvo B11R chassis has bowed out after Volvo Bus UK and Ireland received its last example, with higher-power coach requirements now met by the new B13R.
Regional Sales Director – South Richard Mann says that with the change, Volvo’s UK coach line-up will be based upon the existing B8R, with the 7.7-litre D8K engine, and the B13R, which is powered by the 12.8-litre D13K.
The B13R will form the basis of all 9700 and 9900 models, Mr Mann adds. The first right-hand drive B13R 9700, for an Irish operator, was shown at Euro Bus Expo in 2022 and deliveries of the combination are now starting. Volvo has released a picture of a right-hand drive B13R chassis in shortened form prior to bodying.
News on the future of the 9700 and 9900 after Volvo ceases body manufacture at its plant in Poland during Q1 2024 is expected soon.
Despite the D13K’s increased displacement over the 10.8-litre D11K used in the B11R, Volvo says that it will lead to a 9% improvement in fuel efficiency and enable a higher maximum output of 500bhp. That top setting brings with it 2,500Nm of torque. A new dash console is also part of the B13R specification.
Volvo majors on the B13R being a premium chassis and says that the model is designed to suit “the toughest operational challenges.” It comes with a new G-version of the I-Shift automated manual transmission that delivers faster changes and lower internal friction, while the OEM adds that the gearbox has “software optimised for tour and charter” duties.
A revised rear axle ratio has lowered engine speeds, while the B13R has dual radiators on opposite sides of the engine installation, to which are added electrically powered fans. The chassis is also available in a low-driver layout to suit double-deck or interdeck applications.
