Chassis test mule is sporting a new front fascia with new grille and bumper with air intakes.

These are the latest spy pics of the upcoming fourth generation Renault Clio, caught during a test run in Europe.

Although still a chassis test mule, this prototype is sporting a new front end that we haven't seen before. Beneath the camouflage there's a new grille and front bumper. We can also see prominent air intakes in the bumper but it is not clear if these are just mocks-up for design analysis or part of the actual front fascia to be used.

The next-generation Renault Clio will be longer and wider than the current one. Engine options will include a variety of small petrol and diesel offerings.
