12: Buick Somerset
Marketed as a luxury subcompact, the Somerset was supposed to be the compact car of the future. There were all kinds of technological advancements put into the car. The digital dashboard and interactive buttons throughout the cabin were a nice touch. Unfortunately, the high tech coupe only looked the part of a fast car and nothing else (via The Truth About Cars).

Underneath the hood was the horrible 2.5-liter Iron Duke four-cylinder with just 92 hp of fun and excitement. The car was a flop, and GM would end up moving on from the N-Platform fairly quickly. While the car was praised for its high standard technology, its lackluster performance fell completely flat.
