This is the new Mini Convertible, which will go on sale on March 28 from 15,995.
The car will be available in standard and tuned S forms, with the latter featuring an air-scoop on the bonnet, twin exhausts and a rear diffuser.
Prices for the Cooper S will start from 18,995.
The roof and rear
The Mini features a canvas roof that can be fully retracted or closed in 15 seconds, and which operates at up to 20mph. The roof can also be partially retracted 40cm, giving the effect of a sunroof, at speeds of up to 75mph.
Buyers have the option of fitting one of the odder accessories available for a car, an 'Openometer', which measures how long they have been driving with the roof down.
The anti-roll bar is a single unit on the new car and extends in the event of an accident. As a result it doesn't restrict rear visibility something the old car's fixed anti-roll structure was criticised for.
In another change from the current car, rear passengers will also be able to adjust their headrests, ensuring greater comfort.
Mini says the car is stronger than ever before, despite being 10kg lighter, improving crash protection and the driving experience.
Standard safety features include anti-lock brakes, electronic brakeforce distribution, cornering brake control and stability control, all of which are fitted as standard
Boot space has also increased slightly, giving 125 litres with the roof open and 170 litres with it closed, both up five litres from before. With the rear seats down, the luggage capacity is 660 litres, 55 more than before.
Bike-rack fixing points will also be fitted as standard.
In a change from the current specification, the new Mini Convertible will have air-conditioning as standard, and a cooled glovebox.
The Mini Cooper is powered by a 118bhp 1.6-litre petrol engine. It takes the car from 0-62mph in 9.8sec, averages 49.6mpg and emits 137g/km of CO2.
The Mini Cooper S is powered by a turbocharged 173bhp 1.6-litre engine. It travels from 0-62mph in 7.4sec, averages 44.1mpg and emits 153g/km of CO2.
Both are mated to six-speed manual gearboxes as standard, although a six-speed automatic is available as an option.
Stop-Start, brake energy-regeneration and a gearshift indicator are all fitted as standard to help fuel economy and emissions, which are improved by at least 21%.
