As is typically the case these days, all Countrymans claim a reasonable degree of frugality on paper. The Cooper D is most effective, with a combined figure of 65.7mpg, dropping to 64.2mpg with the automatic transmission. The more powerful Cooper SD (auto only) delivers 61.4mpg. Naturally, CO2 figures are low, though this doesn’t confer the advantage it used to thanks to the new VED system coming into effect from April 2017.
There’s also a nagging feeling owners of diesels will soon be nickel-and-dimed to death through punitive taxation, congestion charge increases and similar, so perhaps a better bet are the petrol models. The three-cylinder Coopers have a combined figure of 51.4mpg, something that remains the same with an automatic transmission but drops to 46.3mpg with the ALL4 all-wheel drive. 45.6mpg is claimed of the Cooper S and 38.2mpg for the John Cooper Works. Expect less than that (for all models) in the real world.
