This was just published at german car mag "auto, motor & sport" but not with the mentioning of a world record, who writes that it is one? BTW: 0-100 km/h was 4.5, 0-200 was 11.7, 0-300 was 30.6. Official price is 345,680 Euros.
Driving was at south italian high speed oval at Nardo after dawn. Fastest car at this event was a tuned up Porsche turbo cabrio of a magazine reader with 357 km/h.
