Maserati GranSport Spyder (2005 to 2007)
Hot on the heels of the GranSport's success, Maserati introduced the equally sporty GranSport Spyder at the Frankfurt motor show in the fall of 2005. The two-seater
roaster also benefited from the developments to the drive-train and suspension. Similar aerodynamic upgrades were also implemented, with new bumpers and side sills as well
as the addition of a rear spoiler (finished in carbon fiber on request).
Maserati enthusiasts could now enjoy the full-throated roar of the 400-hp Maserati V8 in the open air, cosseted in the sporty yet refined interior finished in carbon fiber,
Poltrona Frau leather and Brightex® racing cloth. Equally exciting in and out of town or on the race track, the GranSport Spyder counted amongst the most powerful convertibles in its market segment.
Compared to the Spyder GT, gear-changing in the GranSport Spyder was even faster and the Cambiocorsa's six-speed electro-hydraulic transmission was mapped for involving
rev-matching when changing down a gear. In 'Sport' mode the set-up became firmer, allowing the driver to feel the road to maximum effect. As in the GranSport, the
suspension set-up was firmer with a 10 mm reduction in ride height compared to the Spyder GT.
