• MINI’s petrol engines aren’t the most efficient 
• No hybrid model available, but you can have an EV
• Look elsewhere for best fuel economy

If you’re looking for a MINI with the lowest running costs, the electric model likely makes the most sense as fuel economy isn’t an area where the petrol model shines. 

With the Cooper C, MINI claims up to 48mpg, though we averaged 42mpg during our testing, while CO2 emissions stand at 133g/km. You aren’t significantly penalised for opting for the sportier Cooper S, with the firm claiming 45.6mpg and 140g/km CO2 emissions, though we haven’t yet been able to test this model over any real distance.

If fuel economy is a top priority, the Volkswagen Group’s engines are more efficient – such as in the VW Polo – while you could consider a hybrid hatchback, such as the Renault Clio E-Tech. 

Servicing and warranty

While MINI’s warranty doesn’t last as long as many rival companies, it does potentially suit drivers doing lots of miles, as there’s no mileage cap on it up to three years. Whereas MG’s warranty, which lasts seven years has an 80,000-mile limit on it, for example.

Given MINIs are some of the more premium small cars, servicing will likely be slightly more than more mainstream rivals. The firm offers a service inclusive pack, which covers the car’s servicing up to its fourth birthday (up to 62,000 miles) for £1,044. Electric models are cheaper in this respect, costing just £386 for four years. 

Reliability 

• Certain unknowns about reliability
• But previous MINI Hatch proved dependable
• Software seems good so far

As the new MINI Cooper has only just launched, there are certain unknowns surrounding its reliability. That said, given its underpinnings and engines are loosely shared with the previous Mini Hatch, it should prove fairly dependable as that car has performed well in recent reliability surveys.

We’ve also been impressed by the new Cooper’s touchscreen and its software, which seems seamless and runs without any issues. That might sound a given, but many manufacturers – most prominently the Volkswagen Group – often have hiccups with their software when its cars first launch.
