An engine configuration with two overhead camshafts per row of cylinders. One camshaft operates the intake valves and the other operates the exhaust valves. This is the usual arrangement in engines with multi-valve cylinder heads. Compared to single overhead cam designs, the direct drive used in all Toyota DOHC engines requires fewer moving parts. It eliminates the rocker arm needed to activate the valves, thus improving efficiency and reducing vibration and noise. Compared to push-rod overhead valve (OHV) engines, which use an arrangement by which the camshaft is located in the engine block and opens the valves via long push rods and rocker arms, it eliminates the need for both of these components. With fewer moving parts, there is less inertia. So, an overhead cam engine can run at a higher speed and produce more power than a comparably sized pushrod engine.

Dynamic Laser Cruise Control function has two cruise control modes: a vehicle-to-vehicle distance control mode for maintaining an appropriate distance between two vehicles, and a conventional fixed-speed cruise control mode for cruising at preset speeds.

Electric Motor Power Steering is standard on Prius because when the engine shuts off, a conventional engine-driven hydraulic system would stop working and the electric system is more energy-efficient than hydraulic power steering systems. There is less drag on the engine and it eliminates the need for checking an refilling the system with fluid.
