Alois Barmettler initially made polyester-bodied buggies as well as the 1982 Albar Sonic, which featured upward-pivoting doors and a rear wing reminiscent of the Lamborghini Countach. 

Barmettler also sold the Austrian Custoca based on the VW Beetle in Switzerland under the Albar Jet brand name. The car could be purchased as a kit or as a complete vehicle. Two years later, the Albar Spider was introduced.

In 1984, Albar presented the Sonic GTI with a 1.8-liter VW Golf engine at the Geneva Motor Show, and in the same year a VW Beetle convertible with a Porsche engine, oil cooler, rear spoiler, and fender flares appeared. Albar also converted a standard Beetle convertible into a Super Cabriolet.

From 1991 the Albar Sonic Coupe was offered with a Renault Alpine engine. There were also vehicles with 250 hp V6 and V8 engines with up to 300 hp, replica kits of the Ferrari F40, Ferrari F50, and the Lamborghini Countach, and the Porsche models 356 and 959.
