It will go on sale in the UK in the second quarter of 2015 and sit alongside the regular 500 and larger 500L derivatives in Fiat's line-up.
Two versions of the new model have been created, mirroring a strategy adopted with the 500L and 500L Trekking. One is intended as a chic urban car, while the other has more rugged design themes.
The 500X gets the same retro-inspired styling as the rest of the 500 family, but also includes a more prominent front-end grille design, with chrome trim used around the front bumper. Tinted windows, roof rails and a boot-mounted lip spoiler also feature.
Designed at Fiat's Centro Stile design hub, the new 500X sits on a modified version of the SCCS platform that underpins the Fiat Punto and Vauxhall Corsa. It measures 4.25 metres in length, while the rugged version is 2cm longer. Both versions are 1.80m wide and 1.61m in height.
Boot space is put at 350 litres, and Fiat is playing up the "extensive use of high-grade materials, top-quality finishes and practical storage compartments" inside the car. Personalisation plays a large role in the 500X's appeal: a choice of 12 different body colours and eight designs for the alloy wheels will be offered. Wheels come in three sizes – 16in, 17in and 18in.
