10. Cadillac ELR
The ELR should have been a success but turned to be a failure and a forgotten model even though it’s just two years old. GM’s premium plug-in hybrid was eagerly expected, but the market seemed to ignore it as soon as it was introduced.
Despite its cool looks and premium appointments, the ELR had an underachieving drivetrain, which consisted of a 1.4-liter engine, electric motor, and a pack of lithium-ion batteries. The power output was somewhat satisfying at 217 HP, but the electric-only range was disappointing at just 37 miles. In the end, the base price of $76,000 seemed too much for what the car offered. All of that resulted in less than 3000 units sold, which was embarrassingly low. Cadillac discontinued the model after just two years on the market.
