The first compulsory, albeit speculative, rendering of open-top sibling of the GranTurismo Sport has arrived. Ahead of its Geneva unveiling, Maserati released some photos and details of the GranTurismo Sport that will replace the best-selling GranTurismo S.While nothing has been officially announced, a GranCabrio Sport is likely to launch by the end of the year and this is what Thosphilus Chin believes it will look like. Incorporating the new restyled front fascia that boasts new headlights and DRL LED technology, power will come from the same 4.7-liter V8 that sits in the coupe. As such it should be good for 460hp and a sub-5-second 0-62mph time.Due to decreased aerodynamics difference in weight, the GranCabrio Sport will be slightly slower than the GranTurismo Sport.
