4. Chevrolet Impala: 300-hp $25,760
As we break into the top 5 on our list, we find our last sedan in the club. While it’s the least powerful sedan on the list, the Impala still manages to put out 300-hp, all while costing a mere $25,760. The 3.6-liter V6 manages to make all that power, and even manages to get 30 mpg on the highway. If you’re looking for a cheap 300-hp sedan, you’d better move quick, the current generation Impala is going away real soon, only to be replaced with a more fuel-friendly version.
