Gillet is a Belgian automobile manufacturer, started in 1994 by former racing driver Tony Gillet. The company produces the Vertigo sports coupé, an ultra-lightweight (990 kg) 'bespoke' and hand-built sportscar. The first Vertigo was powered by a Ford Cosworth 2.0 litre 4-in-line. The first Vertigo prototype was finished in 1991 and shown at the 71st Brussels Auto Show in January 1992. In the following two years the car was finalised for production. It was shown at the Paris and Geneva car shows in 1993. Two more cars were built: a second prototype to finalise production design and the first production car, which was used for certification, including the frontal crash-test, seat anchorage resistance and safety belts anchorage resistance tests.
The production Vertigo differed from the first prototype in materials and design. The chassis was fabricated in carbon fibre and honeycomb materials (a technology directly borrowed from Formula One), insuring greater strength and stiffness, while saving (58 kg (128 lb) in chassis weight. The body was given more fluid lines with higher side windows and retractable headlights, making it closer to the first design drawings
In January 2008 Gillet introduced the Vertigo .5, it incorporates features from the Vertigo race car used in the 2007 FIA GT race series.
Famous Vertigo-owners are prince Albert of Monaco and the French singer and actor Johnny Halliday. 25 Vertigos have been sold to date.
