Sports sedans represent an ideal balance for drivers seeking a blend of daily utility and dynamic performance. These vehicles combine the practical benefits of a four-door layout and usable trunk space with potent engines and agile handling. While they are often viewed as versatile machines for family outings or daily errands, their primary design focus usually leans toward raw acceleration rather than fuel conservation.
Achieving high fuel efficiency in this segment typically involves smaller engines, often at the expense of power. However, for those who demand excitement, this list focuses exclusively on modern, pre-owned vehicles (2021 or newer) that deliver at least 300 horsepower, excluding electric models.
1. 2024 BMW 540i xDrive Sedan: 28 MPG
Representing the latest generation of the 5 Series, the 2024 BMW 540i xDrive stands out as a balanced performer. It offers substantial interior volume, with 18.4 cubic feet of trunk space and a flexible 40-20-40 split-folding rear seat. Powered by a 375-hp 3.0-liter turbocharged inline-six, it manages an impressive 28 mpg combined while capable of hitting 60 mph in just 4 seconds.
2. 2022 Audi S3: 27 MPG
The Audi S3 is a compact powerhouse that prioritizes agility and driver engagement. Though its trunk space is more limited at 8.3 cubic feet, it compensates with a high-energy 306-hp 2.0-liter turbocharged engine. This setup allows for a quick 0-60 mph time of 4.3 seconds, all while maintaining a respectable 27 mpg combined.
3. 2021 Cadillac CT4 Premium Luxury: 25 MPG
The Cadillac CT4 Premium Luxury, when equipped with the 2.7-liter turbocharged four-cylinder engine, produces 310 horsepower and achieves 25 mpg combined in its rear-wheel-drive configuration.

4. 2023 Kia Stinger: 25 MPG
The Kia Stinger is recognized for its striking design and practical cargo capacity, offering 23.3 cubic feet of space. The base 2.5-liter turbocharged engine provides a robust 300 horsepower and returns 25 mpg combined in RWD trim. For those seeking even more performance, the 368-hp 3.3-liter twin-turbo V6 is available, though it reduces efficiency to 20 mpg.
5. 2023 Mercedes-AMG CLA 35 4MATIC: 24 MPG
The Mercedes-AMG CLA 35 is designed for those who prioritize driving dynamics in a stylish, compact package. Its 2.0-liter turbo-four pushes out 302 horsepower, facilitating a 4.4-second sprint to 60 mph. While its rear seat is more restrictive compared to other models on this list, it remains a compelling choice for those seeking performance-oriented luxury.
