Just when the list of vehicles set to make their debuts at the Frankfurt Motor Show isn’t mouth-watering enough, Maserati->ke51 is joining the party with the introduction of the GranCabrio.

It took a while for Maserati to finish tweaking the car – a couple of years, in fact – but the wait should be worth it. The car is expected to roll out of the production and into dealerships sometime in March of 2010. In the meantime, fans of the Italian marquee should all look forward to Frankfurt to catch the first glimpse of the GranCabrio in person.

The GranCabrio is expected to come with a more powerful engine than its predecessor, the GranTurismo S->ke2326, thanks in large part to the 4.7-liter V8 engine housed under its hood, capable of producing speeds of as much as 433bhp at 7000rpm and 362lb ft at 4750rpm.

Continued after the jump.

With the added weight courtesy of the extra bracing outfitted on the GranCabrio – it was place there to compensate for the GranCabrio’s convertible, fabric roof design – the car is expected to be slower, albeit not much, than the GranTurismo S.

As has been discussed, the GrandCabrio is slated to run 0-60mph around the 5-second mark and carry speeds of up to 180 mph.

The five-month wait for the GranCabrio to go out on sale should be excruciating for Maserati fans eager to get a piece of the brand’s new sports car. On the other hand, it should give the plenty of time to save up enough money to purchase the car, which is expected to go on sale for around £90,000.

In the meantime, eager fans of the brand have the Frankfurt Motor Show to look forward to. Seeing the new Maserati GranCabrio live in the flesh should give them more reason to penny-pinch until March of 2010.
