Twelve cars are being produced for Middle Eastern market with a special matt white 'Ice' finish, and eleven are being built for the Italian market finished in matt 'Bianco Fuji' paint with pearlescent highlights.
Apart from the special paint, these limited editions are kitted out with a full range of MC Sport Line options available from the Maserati options list.
An aerodynamic package includes double front winglets, rear lip spoiler, door sill inserts, black window surrounds, black exhaust pipes and body-coloured door handles. Carbon fibre door mirrors and carbon-finish door handles are also part of the upgrade.
Other aesthetic features, some of which can also be ordered for Quattroporte S and Sport GTS, include gloss black alloy wheels, interior carbon finishing and MC design aluminium racing pedals.
The suspension set-up includes a lower ride height (by 10mm), stiffer dampers, and larger-diameter anti-roll bars, which minimise lateral load shifts (roll angle is reduced by 20 per cent). Overall the car's rigidity is increased by 16 per cent at the front and 32 per cent at the rear.
MC Sport Line suspension is combined with drilled, slotted front and rear disc brakes, providing a more predictable and a more immediate braking action, the company says.
