MPG, running costs & CO2 Rating

4.5 out of 5

Petrol engines don’t tend to be as economical as diesels but they’ve come a long way; the turbocharged 1.5-litre unit in the entry-level MINI Cooper is claimed to achieve up to 51mpg with an automatic gearbox – although some options such as bigger wheels and a sunroof slightly impede this figure somewhat. CO2 emissions stand at 125-134g/km, meaning the Cooper makes more sense for private urban buyers than it does for company car drivers. The best option for business users is the MINI Electric, which has the lowest possible Benefit in-Kind (BiK) rating – we’ve reviewed it separately.

The 176bhp, 2.0-litre Cooper S isn't quite so frugal, with a quoted 48.7mpg best-case figure combined with CO2 emissions of up to 141g/km. That means a much higher BiK rating, but we think it’s a fair trade-off for the extra power under the bonnet. The range-topping John Cooper Works model – which we’ve also reviewed separately – will return up to 42.8mpg on the combined WLTP cycle and emit 156g/km of CO2.

Road tax (VED) for all petrol MINI hatchbacks is the standard yearly rate and the first year’s payment is usually included in the on-the-road price. The MINI Electric is exempt from VED road tax until 2025 and, as previously mentioned, will save company-car drivers a lot of money in BiK taxation compared to a petrol one.

Insurance groups

The MINI is a relatively small car, but it sits in fairly high insurance groups. The lowest rating (13) is held by the discontinued MINI One, and the Cooper sits in group 20 while the Cooper S falls into group 25 or 26, depending on trim level. John Cooper Works models fall into group 28. While the MINI tends to be a desirable model for young and learner drivers, this could be a stumbling block if it results in a hefty insurance premium.

Warranty

The warranty on all new MINIs is a generous three-year, unlimited-mileage offer. But if you want something that lasts longer, you can look at Hyundai's five-year cover or Kia's seven-year deal.

Servicing

MINI's Pay Monthly Service Plan means you can spread the cost of two services into monthly instalments. An MoT, seasonal health checks and sat-nav map updates are also included in the deal. You’ll need to speak to your MINI dealer for pricing info.
