The fuel consumption of the MINI Cooper varies by model and drivetrain, but recent data shows that the 2024 MINI Cooper Hardtop 2-door with a 1.5L three-cylinder engine and automatic transmission achieves a combined EPA fuel economy of 32 MPG, with 29 MPG in the city and 38 MPG on the highway[1].
The 2024 MINI Cooper Convertible with the same engine and automatic transmission also provides a combined fuel economy of 32 MPG, while the manual version gets slightly lower at a combined 31 MPG[1].
The 2024 MINI Cooper Countryman with a 1.5L automatic achieves 28 MPG combined (26 MPG city and 32 MPG highway), and the all-wheel drive version gets 26 MPG combined (23 MPG city and 31 MPG highway)[1].
Real-world owner and reviewer experiences support these figures; for example, a weeklong test drive of a new MINI Cooper with a mix of 60% city and 40% highway driving resulted in observed fuel consumption matching the EPA estimates[2]. Owner reports for the MINI Cooper S suggest urban consumption can drop to around 25–30 MPG[3].
The 2025 MINI Cooper S 2 Door is rated for 28 MPG city, 39 MPG highway, and 32 MPG combined, highlighting the model’s ongoing focus on efficiency[4].
