Spy shots show a new exhaust pipe configuration which hint at a Ferrari Scuderia influence. New variant/model may simply be a Sport GT S version of the Gran Turismo coupe.
More spy shots coming out of Nurburgring.
These are of a Maserati Gran Turismo prototype doing some laps around a track at the German circuit - a variant/model on which we really have very little info.
What it might be is the GT coupe's equivalent of the Quattroporte Sport GT S. Maybe. Our spy photographer points out that the positioning of the two exhaust pipes coming out of the rear bumper strike a particularly Ferrari Scuderia note and may suggest a new engine is lurking there under the hood.
This is one model we will simply have to wait on for more details.
