OK, I bow to your superior knowledge.
I suppose since R&T is an Amercan magazine they just substituted 'Golf' for 'Rabbit' everywhere as that's what it was known as in the US.
Below is an extract from the R&T article, from which I assumed Super Rabbit to be its real name...

.....the prototype of a Super Rabbit built by Guenter Artz, manager of the Nordstadt Company, a Volkswagen dealer in Hannover. Artz is known for raising many an eyebrow in 1973 with his one-of-a-kind Porsche Carrera-powered 200-km/h VW Beetle.
In 1978 Artz conceived the idea of the Super Rabbit. "We took a complete 928 chassis and drivetrain and built a Rabbit body around it. It required extensive handwork because the size of the engine made it necessary to widen the body by approximately 9 in. Only the doors and side panels are original Rabbit; all other body panels had to be custom-made. The windshield alone cost us $3500," says Artz, who keeps a tight lip about the selling price of his creation. " But, whoever, is ready to put his signature on a sizable.check," promises Artz, "will have the time of his life!"
