The second-generation car of 2003, and the one that made the Prius a shape people recognised.[1] The Kammback body was drawn around a drag coefficient of 0.26, which in 2003 was remarkable for a car of its price.
The powertrain figures here need reading carefully, and the entry says so on each value. The petrol engine makes 57 kW and the traction motor 50 kW, but the system is rated at 82 kW, because the two peak at different points and do not add up. The same is true of torque: 115 N⋅m from the engine, 400 N⋅m from the motor at zero rpm, and no meaningful way to combine them into one crankshaft number, so only the engine figure is recorded.
Its frontal area is the one derived value in this batch. The aerodynamics list publishes a drag area of 0.580 m² for the 2004 car; dividing by the published 0.26 gives 2.23 m². The site’s usual approximation of 0.85 × width × height gives 2.19 m² for the same car, which is a rare chance to check the approximation against something measured.[2]
