A prototype for Maserati's long-awaited redesign of the GranTurismo has been spotted (earlier shots showed a test mule).

It hints at a car with similar proportions to the last GranTurismo but with smoother, more flowing lines. A cleaner aesthetic, like we see on the MC20 supercar, is also planned, it seems.

We know the new GranTurismo will be Maserati's first electric vehicle, but the latest prototype features an internal-combustion engine. This points to Maserati offering versions with electric and internal-combustion power.

Under the long hood of this particular tester should be Maserati's 3.0-liter twin-turbocharged V-6 that debuted in the the MC20, possibly with a mild-hybrid or plug-in hybrid setup attached.

The electric powertrain will be the main focus, though. All new Maseratis will offer electric power, starting with this new GranTurismo. Maserati's electric powertrain, branded Folgore, Italian for “lightning,” will consist of a three-motor system with one motor up front and two at the rear.

The new GranTurismo is expected to be revealed later in 2021. Sales likely won't happen until sometime in 2022, meaning the big grand tourer will likely arrive as a 2023 model here in the United States. A GranTurismo Convertible (GranCabrio in some markets) should arrive about a year after the coupe.

The last GranTurismo reached the end of production in 2019 after a 12-year run. The specialist plant in Modena where it was built is now churning out the MC20. The new GranTurismo is expected to be built at a plant in Turin.

Before we see the new GranTurimso, Maserati will introduce a small crossover called the Grecale. It's been designed on the platform of the Alfa Romeo Stelvio and should debut shortly.
