Cleaner engines, technology and styling changes come with a refresh for the biggest Mini.

IMPROVED range from the flagship plug-in hybrid drivetrain is promised with a mid-life update to the Mini Countryman.

The biggest model to bear the Mini badge continues with the current engines choices, though all have been reworked to improve economy and efficiency. Yet there are no alterations to outputs.

So, the entry Cooper’s 1.5-litre three-cylinder continues with 100kW and 220Nm; the Cooper S 2.0-litre four-cylinder still puts out 131kW and 280Nm and the Cooper SE ALL4 maintains total outputs of 165kW and 385Nm.

However, the unit that uses a 65kW/165Nm electric motor powered by a 9.6kWh lithium-ion battery pack now claims an electric-only range of up to 61km, against 40km previously.

The engines all have particulate filters and the engines in the Cooper and Cooper S now have an exhaust manifold integrated into the cylinder head. A more efficient starter-generator system is standard across the range.

With the cars not coming until the end of the year, Mini isn’t yet keen to lend details on local market specification and, of course, there’s nothing yet on pricing. The hit shouldn’t be too extreme, though, given that sticker revisions in its home country have been modest.

External revisions are similar to those already meted to the three- and five-door hatchback two years ago the the Clubman in 2019.

A new grille with hexagonal comb mesh and a new bumper below differentiate the incoming line from the 2017-released originals. The rear also gets a nip and tuck with Union Jack taillights.

The interior delivers change with redesigned dash and layout, including a “refined surface around the circular control unit” which measures 8.8-inches in diameter and hosts MINI Connected features including Navigation Plus and Amazon Alexa integration and Apple CarPlay.

Equipment on the three trim grades includes 16-inch, 17-inch and 19-inch alloys, digital instrument display, roof and side mirror caps finished in either body colour, white, black or silver depending on model, piano black exterior and interior trims, plus a new range of materials and leathers is offered, including new blue and brown seat colours. As always, there’s an extended range of personalisation options and Mini accessories, including a rear bicycle rack, roof box, luggage mat and all-weather floor mats.
