Fiat released the first pictures of two concept versions of the 500 they are bringing to this year’s Detroit Motor Show. The Tenebra in matte gray is based on the Abarth 500, and the Cattiva – sporting a special two-tone copper and black finish – is based on the Fiat 500 Turbo.

The Abarth 500 Tenebra is finished in Matte Grigio (gray), which gives it a sinister look. But that is only part of the exterior treatment. The car also gets Nero (black) Chrome exterior accents, Gloss Nero headlamp, tail lamp and parking lamp bezels, and new lightweight 16-inch Hyper Nero Chrome Abarth design aluminum wheels. The highlight of the exterior is a Gloss Grigio roof-sized Abarth “Scorpion” logo. Inside the cabin you get Nero leather with Grigio piping and accent stitching.

The Fiat 500 Cattiva has a very cool vibrant Rame (copper) exterior color and contrasting Nero accents for a bi-color appearance. It gets Nero Chrome exterior accents, Gloss Nero headlamp, tail lamp and parking lamp bezels, and a sport-tuned suspension with unique 16-inch satin dark grey painted aluminum wheels. The interior meanwhile is covered in Nero leather with Matte Nero instrument panel as well as Nero leather-wrapped sport-designed steering wheel is hand-stitched with Argento (silver) stitching.

Both cars benefit from Beats audio systems. At the 2013 NAIAS Fiat will also display the 2013 Fiat 500 Abarth Cabrio, the all-new battery-electric 2013 Fiat 500e, and the 2014 Fiat 500L and Fiat 500L Trekking.
