What is it?
This is the Maserati Quattroporte Sport GTS. Last year the Masaerati Quattroporte was given a mild facelift, and at the same time the 4.7-litre V8 engine from the GranTurismo S became available as an option.
Now the range has been extended further with the introduction of this top-end 4.7-litre model, the Maserati Quattroporte Sport GTS.
‘Top end’ in most luxury car terms might equal more speed, but it would also mean more comfort. But this is Maserati. So out go the Skyhook adaptive dampers (replaced by more sporting passive ones), down comes the suspension (by 15mm at the front and 11mm at the rear) and up goes the power and rev limiter.
Okay, so the power's up by only 8bhp (to 433) and the limit by 100rpm (to 7200rpm). But there's more to it than that. The power is up because the exhaust has an active valve which, if you press a button on the dash, sends gases out without damping a great deal of their sound.
Advances in automatic gearbox software, meanwhile, have allowed the rev limit to increase. Apparently autos and high-revving engines aren't naturally suited to each other, so it's only recently that the software has allowed it.
