14: AMC Hornet 360
AMC was in a tough spot toward the end of the 1970s, and if the Hornet is any indication of that, then the reason is obvious. The cars had no style, and performance and reliability were lacking when you compared these vehicles to their domestic counterparts. The Hornet did have some unique features and its 360 V8 was one of the better engines to come out of AMC (via Curbside Classic).
Nevertheless, the car never achieved the type of popularity the brand had hoped for. The stubby stature of the car put it head-on against the Chevy Nova. Consumers were far more preferential to the GM option because of the brand recognition. The AMC brand was just holding on to the Hornet wasn’t enough. Nowadays, though, the Hornet has made a resurgence, as it’s quite easy to swap out a GM V8 engine into it.
