In the early 1980s he moved on to make a coupé styled car with two-seater glass fibre body made in Austria. They were sold in Switzerland as the Albar Jet and Austria as the Strato.
In 1982 he started to make the open Sonic model which no longer relied on the Beetle floor pan but had a proper space frame. Later versions could have VW Straight-4 or Renault 25 engines. A fixed head coupé version was also made.
