It's not as simple as that, as the engine ECU and the gearbox ECU would need to be changed otherwise the shifts would be all wrong - in fact the gearbox might need upgrading to a heavier model to cope with the increased torque - even the final drive ratio in the rear axle might be different!
Our powerful, fuel efficient 9-litre engine and all-new matching automatic transmission mean the Volvo B9TL is optimised for fast and economic operations involving frequent stop-go traffic.
