THE RV might have stolen some looks from the Outback but its engine is pure Impreza. Where the sports-focused RS model picks up the Liberty/Outback 2.5-litre engine, RV makes do with the standard 2.0-litre engine common to the remainder of the non-turbo Impreza range. The SOHC 16-valve horizontally opposed four-cylinder engine produces 92kW at 5600rpm and 184Nm at 3600rpm. Claimed fuel economy figures for the manual RV model are 9.5L/100km on the city cycle and 7.3L/100km on the highway. Normal unleaded petrol can be used to fill the 50-litre fuel tank.
