20: Toyota Highlander Hybrid
The Highlander was a surprise hit for the company when it originally hit the market. The unique look of the SUV and slightly larger proportions than the 4Runner made it a tempting choice for most consumers. The Highlander Hybrid, on the other hand, was not such a great deal and it only offered a slight increase in fuel economy over the standard model (via Car & Driver).
The Highlander Hybrid has been seen in a few different incarnations, none of which have been particularly popular. With the current model achieving such great fuel economy numbers, there hasn’t been a point in having the Highlander Hybrid in the lineup.
