The luxury four-door coupe market is relatively new, but it has booming recently with new models being added frequently.
Though the last version of the Quattroporte was considered more of a formal sedan, the latest version occupies this new class.
BMW's 6-Series Gran Coupe offers similar power and performance, including the range-topping M6 version which outdoes the Quattroporte GTS somewhat, while offering its own take on dramatic exterior styling and creature comforts.
Mercedes-Benz's CLS-Class, including the CLS63 AMG 4Matic, is perhaps the most familiar of the four-door coupes, and for good reason: it's a very good car, with comfort, power, and luxury in spades, and one of the originators of the category.
Porsche's Panamera is perhaps the sportiest of this group, and it's also the most efficient, with a new plug-in S E-Hybrid model on offer since 2014.
The Audi A7 has S7 and RS 7 spice to add to this mix, and prices nearly overlap those of the base Maser.
