Maserati will be showcasing a new, more powerful GranTurismo at the Geneva motor show. The GranTurismo S will feature the same 4.7-litre V8 as the sold-out Alfa Romeo 8C. This gives it a boost of 35bhp to 434bhp, and an extra 0.4-litres over the standard GT, which was released late last year.The ZF gearbox is also replaced in favour of a fast shifting, dual clutch 'electro-actuated' gearbox arranged in the transaxle layout.Other changes include new Brembo brake system already used in the Quattroporte Sport GT S, which uses iron and aluminium brake discs paired to six-pot callipers.The exterior also gets a more subtle tweak, which includes red highlighted Trident badge, new alloy design and more deeply sculpted sills. The cabin receives a unique leather and Alcantara trim, and new seats.All the updates have been carried out to make the GT more performance focused, and a new gearbox, engine and braking system could certainly do the trick. We'll have to wait until the first drive for the official verdict, but until then we'll have to be satisfied with more details and pictures of the GranTurismo S after its show debut on March 4th.
