SEAT Tarraco review - MPG, CO2 and running costs

​Predictably, the 2.0 TDI diesel with manual gearbox is the most fuel efficient Tarraco, offering a claimed average of 52.3mpg on the WLTP combined cycle. In common with all the engines, avoiding the larger alloy wheels will help to optimise fuel economy. Adding a DSG gearbox to the diesel brings a fuel penalty, with this version dropping down slightly to an average 51.4mpg.

The 1.5-litre petrol sees a reasonable 42.4mpg when mated to the manual ‘box - dropping to 40.4mpg for the automatic. Choosing the diesel engine and entry-level SE trim will give you the least-polluting Tarraco, generating 142g/km of CO2. The petrol-powered XPERIENCE is the least eco-friendly, emitting 165g/km.

Insurance groups

The Tarraco ranges between insurance groups 18-20. The cheapest version to insure is the 1.5-petrol in SE trim fitted with the manual gearbox. In comparison, the closely related Skoda Kodiaq resides in groups 21-28.

Depreciation

Our experts predict that the Tarraco will retain between 44 and 47 per cent of its initial value over a typical ownership period of three years or 36,000 miles. The best performer is the diesel-powered Tarraco in SE trim with a DSG automatic gearbox.
