Top Cars

There are a few things Maserati could do to make the GranTurismo look better than it does, but not many. One option is to surround it with unspeakably beautiful women. Another is to remove the roof. Thankfully, they opted for both here in Frankfurt, where the Trident marque took the wraps off the new GranCabrio.

The girls are a regular fixture for Maserati. But the convertible version of the GranTurismo coupe has been a long time coming. Details and the first batch of photos broke a few weeks ago, and we just got our first up-close-and-personal with what is, believe it or not, the only proper four-seat cabriolet currently on offer from Italy.


PRESS RELEASE:

The new Maserati GranCabrio

The introduction of the GranCabrio – the Trident's third prong – completes Maserati's product line-up that now consists of three different families of models: Quattroporte, GranTurismo, GranCabrio.

The GranCabrio represents the very essence of Maserati in terms of open-top cars. It's a Maserati in the purest sense of the word: from the unmistakable style by Pininfarina to the spacious interior, from the craftsmanship of each detail to the driving pleasure and performance. The Maserati GranCabrio enriches all five senses in a shared open-air experience, without sacrificing comfort and performance. A dream car designed and built for men and women who love to live life in an understated – though sophisticated - manner. Like all the made in Maserati open-top convertibles: special cars aimed at refined connoisseurs.

The GranCabrio is continuing the Maserati tradition in open-top fine automobiles, beginning with the 1950 A6G Frua Spyder, and continuing through a long list of significant and thrilling open air models. However, in adding to this tradition, the GranCabrio opens a new chapter, because never before have four-seater top-down models ever been produced at the Viale Ciro Menotti Maserati factory in Modena. Four proper seats are provided, so that the rear passengers are not merely supporting actors, but co-stars of the journey.

The GranCabrio is powered by a 4.7 liter V8, 323 kW engine and is the convertible with the longest wheelbase on the market (versus its direct competitors). The GranCabrio's roof is strictly canvas-made, emphasizing the link with the Maserati tradition.

The Maserati GranCabrio will be marketed starting next winter, and experienced by customers the world over from the following spring.
