The next-generation Hyundai i30 five-door hatchback has been spied undergoing testing in the European Alps.

First spotted in August 2015, prototypes of the new i30 were last spied in February in Australia during hot weather testing.

From what we can deduce through the car's protective cladding and camouflage, the new hatch seems to have a flatter, more formal side profile.

Up front, there's a large six-point grille taking up much of the surface area of the front bumper. The grille is flanked by thin headlights and, in the lower section, by a vertical strip of LED driving lights and a small fog light pod.

At the rear, the new i30 will sport a version of the company's thin tail-light treatment, with these prototypes featuring LED light tubes.
