About the 2018 MINI Convertible

3rd generation (F57), introduced for 2016; 2018 is the third model year and the last pre-facelift year before the 2019 refresh.

MINI positions the Convertible as a premium small car that mixes open-top fun with everyday usability. It is not a two-seat roadster; its appeal is a compact four-seat layout, a power soft top that can act like a sunroof or fully open roof, quick steering, and a cabin that feels more upscale and more characterful than most small cars. Buyers choose it for style, nimble city manners, and a more playful personality than mainstream subcompact convertibles.

The Cooper is the easygoing entry point, with a 134-hp turbo engine and a power soft top that also opens partway like a sunroof. The 189-hp Cooper S brings stronger acceleration and sport seats, while the 228-hp John Cooper Works adds a sport-tuned suspension, stronger Brembo front brakes, and LED headlights.

“My MINI is extremely fun to drive. There are trade offs however. There is very little cargo room and the backseat is not comfortable or roomy enough for an adult for any length of time.”

No rating

“The fun factor is very high. Comfort is less than a high end luxury vehicle, but is outweighed by the features and enjoyment of driving this one.”
