From the outside, the new Quattroporte retains revised styling that debuted in 2017 but upgrades include standard adaptive LED headlights, with the dynamically-oriented GranSport models also gaining a gloss black grille.
Under the skin the Quattroporte ditches its previous hydraulic power steering new a new electric power steering system, as seen on the revised Levante SUV, which allows for the fitment of more advanced driver assist systems including lane keeping assist, highway assist (maintaining lane position and following distance on some roads), and active blind spot assist that can steer the Quattroporte out of the path of another vehicle during lane changes or while cornering.
Also included with the upgraded technology are a 360-degree camera system and traffic sign recognition, plus soft-close doors.
Under the bonnet of the Quattroporte S is a more powerful version of Maserati’s Ferrari-assembled 3.0-litre V6 which bumps peak power up to 321kW and peak torque to 580Nm, increases of 19kW and 30Nm compared to the previous version.
Standard V6 versions, either the 257kW500Nm turbo petrol V6 or 202kW/600Nm turbo diesel V6 retain their existing outputs, while the range-topping GTS also holds onto its 390kW/650Nm twin-turbo V8.
Both the Quattroporte and Quattroporte S are available in a standard, unnamed base trim or can be upgraded with either luxury themed GranLusso or sport-styled GranSport trims, with the GTS only offered in the two higher-spec versions.
All versions come equipped with an 8.4-inch touchscreen infotainment system including navigation, Apple CarPlay and Android Auto functions, wood interior trims, power-adjustable steering column, 7.0-inch TFT instrument cluster flanked by analogue gauges, leather seat trim, power-adjustable from seats.
Opting for the GranLusso package adds 20-inch wheels, four-zone climate control, Zenga Edition silk interior highlights, rear sunshades, heated rear seats, heated and cooled front seats, plus upgraded Bowers and Wilkins audio on the GTS and the option for a two-position rear seat with individual power adjustment and seat ventilation.
The GranSport brings red brake calipers, piano black interior trim, sports pedals, 21-inch alloy wheels, and unique sports bumpers.
