Toyota Prius V increased power consumption for acceleration and maintaining speed on level roads on Toyota Prius V

Some Toyota Prius V owners report experiencing concerns related to power consumption during acceleration and maintaining speed on level roads. These issues can arise from the vehicle's 1.8 litre Atkinson cycle engine, which delivers 73kW of power and 142Nm of torque, combined with a 650 Volt electric drive motor providing 60kW and 207Nm of torque. While the combined power reaches a maximum of 100kW, some owners note that achieving optimal fuel efficiency of 55+ MPG at speeds of 35-45 mph may require careful monitoring of battery power, especially when utilizing the Power mode for quicker acceleration, which could impact MPG temporarily. Overall, these factors illustrate the Prius V's balance between performance and fuel efficiency, highlighting the importance of understanding power consumption dynamics.
