20. Alfa Romeo 4C
In 2013, Alfa Romeo introduced the 4C, but nobody expected such a car from the company. The 4C was a “junior supercar” with a carbon-fiber tub, lightweight construction, a cramped interior, and a four-cylinder turbocharged engine.
The heart of the 4C was a tiny, 1.8-liter engine with a turbocharger sending 238 HP to the rear wheels. Unfortunately, due to slow sales, Alfa discontinued the car. That left consumers wanting another affordable but still immensely capable Italian sports car.
