It will be displayed at the Motor Show by premium in-car infotainment company Eclipse, along with state-of-the-art Eclipse audio, video and navigation systems as amazing as the car itself.

Flat Out is Andy Saunders' second car to visit Melbourne, as his "car of the Future" X-2000 was displayed at the show in 2000.

To put Flat Out's height in context, an original Mini is almost two-and-half times its height at 135 cm and a current Mini towers above it at 142 cm.

Andy Saunders chose a Fiat 126 as his donor car because it has the lowest engine height he could find, with a tiny water-cooled two-cylinder engine snuggled neatly in the back.

Although the Fiat 126 is not well known in Australia, some people will remember the Polish-built version known as the Niki 650.

Saunders built Flat Out in just three days at Britain's 40th Annual Autojumble last year at the National Motor Museum in Beaulieu, Hampshire.

Working 18-hour days, he was ably assisted by engineering guru Jim Chalmers, whom he met on the BBC TV programme "Panic Mechanic" and Doug Brown, an Aston Martin designer responsible for the interior of the DB9 and for Flat Out's superb hand-stitched leather interior.

Andy Saunders started the "World's Lowest Car" battle with his Mini-based Claustrophobia in 1985 and the record has since changed hands at least twice, most recently standing at 59.9 cm.
