[1] Tony Gillet was a successful racing driver, winning the Belgian hill-climb championship in 1979 and 1980[2] and competing in two Dakar Rallies.

The body was given more fluid lines with higher side windows and retractable headlights, making it closer to the first design drawings.

During the same year, Gillet had the opportunity to collaborate with the company Transnubel by producing 3,750,000 cubes in composite intended to the Belgian nuclear industry.

The Vertigo Streiff was originally developed with a modified version of the Alfa Romeo V6 engine, with 3.6 L and 360 PS (265 kW; 355 hp).

In the 2008 FIA GT season Renaud Kuppens raced using a Gillet Vertigo.5 with a Maserati 4,2l V8 engine tuned to Group N specification.

Gillet designed and completed the first Vertigo prototype with the 3.0-litre Alfa Romeo V6 engine for road use in 1991, and shown at the 71st Brussels Auto Show in January 1992.

[7] The model had a carbon fiber body wrapped around an Alfa Romeo 3.6 liter V6 capable of 360 bhp, with a 0-62 mph time of 3.2 seconds.

[5] There were some changes in several sections: the 4.2-litre Ferrari/Maserati V8 replacing the 3.0 L V6 from Alfa Romeo, weighing around 2094 lbs with a 2,340 mm wheelbase, building up the suspension and brakes with double wishbones and tweaked absorbers and springs in the front.
