TheCV8 rated at 410 kW(550 bhp) powers the Alvis Vehicles Warrior IFV vehicle, used by the British Army in the Gulf in 1991 and subsequently in the former Yugoslavia. It has also been selected, after competition, by the Kuwait armed forces. In Warrior, the engine is coupled to the Perkins Engines Company X300-4B cross-drive transmission (see later entry). This combination gives the vehicle excellent mobility in the harshest of terrain with maximum power to the tracks under all conditions. The cooling package ensures that the vehicle will perform at its best even with ambient temperature above 50°C.
Currently developing 100 bhp per cylinder, the structural design of the CV8 will allow outputs of 150 bhp per cylinder or more. With the application of integrated subsystems, Electronic Unit Injectors (EUls), Engine Management System (EMS) with diagnostics, prognostics Built-in Test (BIT), Built-in Test Equipment (BITE) and advanced air management systems, much higher ratings could be achievable in the near future. EUls allow much greater flexibility of fuel management, for example, higher injection pressures, variable injection timing whilst running and even cylinder cycling whilst idling. This could help reduce fuel consumption, improving Brake Thermal Efficiency, lower smoke and emissions levels and control combustion pressure rise, thereby reducing total noise.
