2014 |
Initially, at least, the Ghibli is available in the United States with two turbocharged 3.0-liter V6s designed by an F1 engine guru and manufactured by Ferrari. You can choose between 345 horsepower (at 5,250 rpm) driving the rear wheels and 404 horsepower (at 5,500 rpm) driving all four. The all-wheel-drive system in the tested car sends all power to the rear wheels by default, but at speeds under 80 can shift up to half of it forward in a sixth of a second. In either case the transmission is the same ZF manually shiftable eight-speed automatic employed in many Audis, BMWs, and Jaguars.
Though the Ghibli's gearing is surprisingly tall, after a brief lull when you first stomp on its throttle this is a very quick car, capable of getting to 60 mph in under five seconds. The BMW with its similarly sized but 315-horsepower six and somewhat higher curb weight (4,365 vs. 4,114 lbs.), while also plenty quick for most drivers, isn't as quick as the Maserati. Road tests elsewhere suggest it could take almost another second to get to 60. The Audi, though its supercharged V6 is officially rated for a mere 310 horsepower, pulls especially strongly through its midrange and roughly splits the difference between the other two.
This said, BMW and Audi also offer (for a considerably higher price) powerful boosted V8s that can trounce the Maserati. If and when the Italians feel the need to match these, they can offer the Ghibli with the 523-horsepower turbocharged 3.8-liter V8 from the closely related and longer (but not much heavier) Quattroporte GTS.
While the new turbo V6 doesn't have the spine-tingling exotic shriek of the high-winding naturally-aspirated V8 (power peak at 7,000 rpm) in the 2005-2013 Quattroporte, it sounds much more lusty than BMW's inline six. When maximum output is called for, valves open up in the exhaust, letting out much brapping and crackling (on shifts) and throaty roar (in between them). Hit the S(port) button to the left of the shifter, and these valves remain open all the time. Most owners will probably opt not to do this, as the exhaust noise that's exhilarating when thrashing the car along a curvy road (or, even better, a track) can become a tiresome drone when simply cruising around town. Easy fix: tap the S button again to disengage sport mode. This done, the V6, if not the quietest, is easily refined enough for luxury sedan duty. It's not a high-strung exotic the way the engine in last year's Quattroporte was.
Aside from the aforementioned initial lull, which could be the fault of the throttle programming, the ZF transmission performs as well here as it does elsewhere, with smooth shifts in casual driving and firm, quick ones in, well, decidedly less casual driving. It can be manually shifted via either the lever or magnesium paddles that flank the steering wheel.
