Vauxhall Tigra — MPG & Fuel Costs 2025
A compact two-seat coupe-convertible with a folding metal roof, based on the Corsa platform.
The second-generation Vauxhall Tigra (Tigra TwinTop) was a popular two-seat sports car featuring a retractable hardtop roof. Built on the Corsa C platform, it combines low running costs with open-air styling.
Under the hood, drivers could choose between simple 1.4 or 1.8-litre petrol engines or the highly frugal 1.3-litre CDTi diesel. The diesel is incredibly economical but quite rare in the UK market.
The lightweight nature of the Tigra ensures good fuel economy, with petrol models easily achieving 40 MPG real-world and the diesel version pushing past 50 MPG under normal driving cycles.
