The changes include a new centre console layout, door inserts and door armrests. But the most noticeable change is that the window switches have been moved from the centre console to the doors, with the driver's door now incorporating controls for all of the windows and door mirrors together in one place.
There's also new surrounds for the speedo and air vents finished in Carbon Black with an inner ring finished in high-gloss black or, if you opt for the Chrome Line pack, in chrome.
New exterior colours have been added - including Brilliant Copper Metallic and Blazing Red Metallic - while the equipment packages have also been revised, with the aim of making customisation as easy as possible for buyers.
As before, the rear seats comes as a three-seater bench, with two individual rear seats available as a no-cost option.
The three petrol and three diesel engines remain unchanged and range from 89hp to 181bhp. The John Cooper Works Countryman is powered by a 215bhp turbocharged petrol engine.
All-wheel drive is standard on the JCW model, and will remain as an option for the Cooper S, Cooper SD, and Cooper D Countryman. All models bar the One D can still be ordered with a six-speed automatic in place of the standard six-speed manual.
The revised Countryman will arrive in showrooms this November, with no change to pricing, which starts from £16,510.
