11: Toyota Avalon Hybrid
What does it take to make a successful family sedan? Well, in the case of Toyota, that would be its best-selling Camry. But the brand also offers the Avalon as well, a car that has never had a solid place in the lineup (via Car & Driver).
The Avalon Hybrid only added to the confusion by offering a car with a higher price tag but offered less value. The Avalon Hybrid never sold very well, and the car only continues to cloud the already expansive lineup.
