The facelifted coupé and convertible models get minor aesthetic tweaks as well as updated technology inside.
The Pininfarina-designed bodies feature a lightly adjusted rear bumper and a new grille with a three-dimensional design, taking inspiration from the Alfieri Concept of 2014.
Maserati has also improved the aerodynamic performance of the GranTurismo's and its drop-top sibling, using lower air ducts to reduce the former's drag coefficient from 0.33Cd to 0.32Cd. The GranCabrio improves from 0.35Cd to 0.33Cd.
The models are available only with a naturally aspirated 4.7-litre Ferrari-built petrol engine and six-speed ZF automatic gearbox. It produces 454bhp at 7000rpm and 384lb ft at 4750rpm, which enables a 0-62mph sprint of 4.8sec and a top speed of 186mph for the regular Sport coupé model. The lighter MC model trims 0.1sec and adds 1mph to those figures respectively.
