The BMW 7-Series is the legendary (yet conservative) full-size sport-sedan entry; in some of its forms, it can come quite close to rivaling or beating the Panamera's performance, yet its conservative roofline is going to be cause for some to dismiss it from this group.
The same holds true with the Mercedes-Benz S-Class, which is the comfort and technology king in this group, albeit without quite the level of driver connection (although edgy S63 and S65 AMG models are there to hammer at the straight-line performance).
Mercedes’ CLS-Class offers a roofline that's sexier in some respects than that of the Panamera; yet it doesn't drive like a high-performance sports car, in the same way.
Maserati’s Quattroporte offers a markedly more aesthetic choice, and its interior is downright opulent, though like the 7-Series, it lacks the sharper end of performance offered by the Panamera.
Finally, the Aston Martin Rapide S offers a presentation that's a lot like that of the Panamera, but the Aston is actually a much edgier, more compromised sedan; you'll have more head-turning exclusivity with the Rapide, though.

The 2016 Porsche Panamera looks like a sports car and drives like one, yet it delivers executive-level ride comfort and cabin appointments. |
Don’t let the conservative wrapper fool you, the 2016 BMW 7-Series charges boldly into a new generation as a sporty big sedan, with new ride-and-handling tech, space-age construction, and a plug-in hybrid version. |
The 2016 Mercedes CLS-Class looks great—inside and out. But a new E-Class and more efficient powertrains may outrun the potent "four-door coupe" sooner rather than later. |
Coupe, Cabriolet, and Maybach versions—and even a Plug-In Hybrid—make the 2016 Mercedes-Benz S-Class far more diverse and adventurous than it used to be; it's now not just a flagship sedan, but a family of flagships. | Even though it has four doors, the Aston Martin Rapide S is worthy of the wings and heritage thanks to its unparalleled good looks. |
The 2016 Maserati Quattroporte is a rare sight, but shouldn't be—it's gorgeous, with sharp, Ferrari-flavored performance. |
