Ford Focus RS — MPG & Fuel Costs 2025

A legendary four-wheel-drive hyper hatch. Powered by a 350hp EcoBoost engine with drift mode.

The third-generation Ford Focus RS is a legendary performance car featuring a sophisticated torque-vectoring all-wheel-drive system and a 350 horsepower 2.3-litre engine.

Because of the mechanical drag of the four-wheel-drive system and the high state of engine tune, it is a thirsty car compared to standard hatchbacks.

Mixed real-world driving typically yields around 26-28 MPG. Motorway runs can see 32 MPG if driven carefully, but hard B-road driving will see fuel consumption rise dramatically.
