In 2008, Fiat launched a special edition 'By Diesel' 500. In a partnership with Fiat and Italian clothing brand Diesel, with a production run of 10,000 planned. The 500 by Diesel is available in a choice of three exclusive colours, and can be distinguished from standard 500s by unique alloy wheels, 'Diesel' logos and burnished metal bumper and side-rub inserts. The interior features denim upholstery with coloured stitching and a 'Diesel' branded gear knob. The 500 by Diesel is based on the 500 Sport, using the same 1.2 L petrol, 1.4 L petrol and 1.3 L diesel engines.
