Dodge Nitro
The Dodge Nitro was an interesting SUV concept that was based on the Jeep Liberty. The upright styling of the Nitro was radical looking at the time. There was an R/T version of the SUV that was nothing more than an appearance package. From the outside, the Nitro looked unique, but it wasn’t all that great (via Readers Digest).

The Nitro was never a sales hit for Dodge, and the SUV was discontinued in the late 2000s. The Nitro didn’t offer anything unique that wasn’t already on the market. Consumers looked for unique SUV models and the Nitro was underpowered and overpriced.
