Prototypes for Maserati’s next model, a new coupe-cabrio based on the same platform as the Ferrari California, were first seen testing more than a year ago but soon disappeared once engineers started focusing on completing the car with the Prancing Horse badge. New spy photos reveal the Maserati version is back in testing, though from outward appearances it still has considerable work ahead of it. Looking much like the California did during testing, the Maserati bears a large and awkward-looking camouflage unit covering the rear of the car. The last that had been seen of the Maserati prototypes was back in February when a mysterious GranTurismo with ill-fitting body panels was spotted in Italy.
