Vauxhall Frontera — MPG & Fuel Costs 2025

Vauxhall's classic rugged 4x4, available in short-wheelbase Sport and long-wheelbase body styles.

The Vauxhall Frontera was one of the UK's first mainstream lifestyle 4x4s, built in Luton. It features a traditional body-on-frame chassis and selectable low-range four-wheel drive.

Due to its heavy build and brick-like aerodynamics, the Frontera is not a fuel-efficient vehicle by modern standards. The 2.2 DTi diesel is the pick of the engines for towing and general economy.

Real-world fuel economy is low, with the petrol models struggling to exceed 22 MPG and the DTi diesel averaging around 28-30 MPG in daily mixed usage.
