The special edition adds 16-inch chrome alloy wheels, new 'GT' bumpers at the front and rear, a chromed rear diffuser and extra tinted rear windows and tailgate.

Prices start from £17,095 for the hatch, rising to £17,595 for the Coupe and £17,895 for the Sport Tourer - which also includes 1600 litres of storage space.
The car will be sold from today until autumn this year.
