the Quattroporte overall and 20cm shorter in wheelbase - will have "a more-focused, sportier philosophy", underpinned by an engine range that features two all-new twin-turbo V6s and a similarly clean-sheet V6 diesel. All come with mechanical limited-slip diffs as standard and even the diesel will hit 0-62mph in 6.3 seconds, and has 275hp and 442lb ft of torque. An XF Diesel S, also with 275hp, is four tenths faster but it's not a bad effort given this is Maserati's first ever diesel.
The 3.0-litre twin-turbo petrol engines, built in Maranello by Ferrari, will come in 330hp and 410hp S tune and both are closely related to the V8 in the Quattroporte, sharing block architecture, manifold design and bore among other things.
Right-hand drive cars will all be rear-driven, other markets getting the option of Maserati's Q4 four-wheel drive system which sends power forward from a default 0:100 rearward bias to 50:50 when needed. In all cases ZF's eight-speed handles shifting duties.
If you discount the mainstream German saloon rivals as a bit stodgy and staid, the Ghibli's natural competition would be led by the Jaguar XF and the newly refreshed Porsche Panamera (also unveiled in Shanghai with a new 420hp downsized twin-turbo V6, entirely coincidentally...), with 'coupaloons' like the Mercedes CLS,BMW 6 Series Gran Coupe and Audi A7 also featuring on the shortlist. The Maserati badge carries more romance than any of those and that, for many, would be enough on its own combined with some suitably sexy bodywork. That the mechanical spec sounds so convincing too should have these established equivalents looking distinctly nervous, depending on where Maserati chooses to pitch the price.
Suddenly that near-tenfold increase in sales doesn't seem like such a daft boast after all.
