Current big Ferraris are front-engined, not front wheel drive.
The FZ50/GTR is rear engined like a Porsche, and to me it has an ingenious hybrid shape that's like an illicit lovechild of Ferrari and Porsche stylists.
what are current big ferraris? heavy ones? because when I think to Ferrari (current models), except for the maranellos and very few others, those cars are mid-engined, and they are not very light
Alrighty, IMO the XR series looks like an early supra mixed with a second generation RX-7, the RB4 looks like a supra/celica with 3000GT taillights, the FXO looks like a Honda Civic and an Accord, and the FZ50 looks like a cross between the Nissan 350Z, a Porsche 911, with Ferarri taillights.
The only Ferrari that's still on production and mid-engined is a F430, and that cars weights 1450 kilograms, that's about the weight of an Golf Mk5 with some extras
Sure, 1450 kilograms is not very light. But in comparsion to other modern cars it's still not that much.
Cars getting heavier all the time due to new savety regulations, cause they're getting stiffer and because of all the little electronic helpers and extras
EDIT:
I'm not saying that there aren't any light cars around, but most of them are very spartanic (not that I wouldn't like it that way ) and most of them are only build in small series
