The Prius Prime has been the #2 highest selling plug-in vehicle, behind only the Tesla Model 3. As Hersbird points out, if Toyota had focused on hybridizing all vehicles and having a Prime version (plug-in), they would be making a killing by offering the smallest size battery that qualifies for the maximum subsidies.

Toyota screwed up offering the Prius Prime with an 8 kWh battery because it eats away their federal tax credits yet doesn't yield the full credit amount. They should have made it twice the capacity, with a 50+ mile EV range and received the full subsidy amount. With the Volt discontinued, there is no vehicle in that class to compete with.

The RAV4 Prime should not have been a compliance vehicle, but marketed and sold as a flagship product.
