Gransport Spyder
from 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.

Forbes Autos reviewed the GranSport & GranSport Spyder in July 2006:
“This oh-so-Italian duo brings a new level of grace, classiness and brio to the upper-end sports-car market, plus a few features that none of the competition has… At a time when automotive interior styling is too often clichéd and stultifyingly familiar, the Italians surround you with color and quality that suggests Gucci, Prada, Fendi and Versace… Their styling is tastefully understated and, like a beautiful sculpture, carries subtleties that can only be appreciated upon close inspection… The car is remarkably nimble despite its ample interior space and luxurious cockpit… It gives a driver confidence… You may find yourself addicted to top-down motoring in the GranSport Spyder as the rich roar of the potent V8 bellowing through the exhaust pipes reaches your ears unfiltered… Buy this vehicle if: You’re bored with the default German choices – aka Porsche 911 – and enjoy the superior tactile and aesthetic only Italians can manage.”
