The small hot hatch is due for release sometime this spring, and is expected to receive a power hike along with tweaks to its design.
Like the normal 500, the Abarth’s physical changes will be small, but these test mules confirm it’ll get new taillights, restyled bumpers and different alloys.
The 2016 model is expected to be powered by a new version of its predecessor's turbocharged 1.4-litre engine, with peak output increasing on the current car's 133bhp.
Pictures of a mule with a quad tailpipe setup seem to suggest the 595 - an even hotter version of the 500 - is also in final stages of development. With a similar increase in performance, power for that model could edge towards the 200bhp mark, enabling a 0-62mph time of under 7sec.
