HURACAN,
Dream on, brotha' ... New fuel mileage regulations demand cylinder deactivation; Superleggera will have it, too!
(BTW ...Press release says nothing about stop/start for North American versions).

Nobody said there was a power increase for 16'...BUT, Lexx confirmed the redline is now at 8700rpm!! Wild screaming revs in comparison to those 15's.
According to your way of thinking: This car can go 280mph, no matter what the Speedometer Display says!!
