The 'SX' was also available as a 'Citymatic' which features clutchless manual gearchange, and a 'Sporting' with the larger FIAT FIRE series 1,108 cc 40 kW (54 hp) engine, 20 mm (0.8 in) lower suspension and anti-roll bars added.

A close ratio gearbox, sill kick plates, embroidered headrests, leather gear lever and steering wheel, colour highlighted trim in the bumpers, side skirts and a spoiler also available.

A 'Michael Schumacher' edition of the Sporting, with ABS and the Abarth styling kit, was also launched at this time to celebrate the Ferrari driver's Formula One success.

This model was almost identical to the 'Sporting' with the Abarth kit with the exception of a chrome gear lever surrounds and Michael's signature on the boot lid and side skirt.

The latter was fitted universally with multi point fuel injection from 2001, replacing the old 899 cc unit due to the tightening emission regulations.

The Seicento Elettra featured a 30 kW three-phase asynchronous electric motor powered by eighteen 12V lead-acid batteries in the engine bay and beneath the rear seats.

[6] German tuner Novitec created a special edition of the Fiat Seicento, adding a turbocharger and six speed gearbox to the little car.
