Italdesign debuted its latest convertible version of the company's Zerouno supercar at the Geneva International Motor Show in the Palexpo convention centre on Tuesday. The Italdesign Zerouno Duerta is powered by a 5.2-litre V10 Audi petrol engine with up to 610 horsepower. It also uses Audi's permanent four-wheel-drive system, taking the car from 0-62 mph in 3.2 seconds. The top speed is... Еще estimated at 205 mph (330 kmh). The final price has not been confirmed, although it is thought to top €1.5 million ($1.8 million). The number of cars entering production will be limited to five examples, much like its coupe version, that debuted at last year's GIMS. Over 700,000 visitors are expected to attend the 88th edition of the Geneva International Motor Show, which will open its doors to the public on Thursday. The exhibition will show 900 models, with more than 110 World and European Premiers from 180 exhibitors.
