What's the difference?
Big sedans are not in vogue at the moment and huge luxury sedans were on the way down before the humble Commodore and Falcon departed the upper end of the sales charts. The Germans, who have always done a spectacular job of these flagship sedans, cheerfully persist with these cars.
Absolutely loaded with fascinating technology that bleeds its way down to the more mainstream models, they represent the zenith of the brand's innovation and style. The A8 is certainly that.
What it isn't, is particularly sporty, but after two years since its launch, V8 power has reached the fourth-generation super-sedan to deliver the latest iteration of the iconic S8.
Maserati's Quattroporte is part of a dying breed. A decade or so ago, the European manufacturers took a huge amount of pride in their range-topping big luxury sedans, cars you can either drive or be driven in, bristling with the latest technology.
In 2015, all we hear about are the range-topping SUVs from those makers, with cars like the S-Class and 7 Series fading slowly into irrelevance.
While by no means low-tech, the Maserati Quattroporte takes the high style route, focussing on a luxurious interior with that handmade feel.
The S8's existence is a source of joy for me because it's not a huge SUV. Yes, it's a huge sedan but it's a reminder that the technological flagship is alive and well, at least in Germany. And the important thing about these cars is the way the toys filter down through the rest of the range. That used to take years but we're seeing this cool stuff a lot more quickly, right down to the A1.
The S8 punches, and punches hard in this rarefied part of an already shrunken section of the market - the twin-turbo V8 matches its German rivals, it's lighter and it's as well-stacked as any of the three. What it doesn't do, however, is shout about itself the way the other two do. It's the incognito choice.
Beauty is way more than skin-deep in the Quattroporte and while the 330 doesn't have the punch of the S, it's hardly that much slower. Maserati reasons you will want to spend the $25,000 saved on options, concentrating on the Italian craftsmanship rather than the outright performance available in the V8 or the efficiency of the less aurally attractive diesel.
As with any car of this type, you've got to want one in the first place, but for a big, beautiful sedan, there's nothing as good looking this side of an Aston Rapide. The Quattroporte 330 does nothing to dim the allure of Modena's big mover and, if you're that way inclined, nobody on the outside will ever know.
