The Car Connection's Take
TCC Rating

TCC’s Bottom Line
The 2012 BMW 7-Series is the Bavarian automaker's flagship model, and it cleverly wraps vast interior space, industry-leading tech, and the expected BMW fleet-footedness. The Mercedes-Benz S-Class has a wide range of personalities--all of them superbly comfortably, some of them outrageously powerful. Bucking tradition and the ordinary, the 2012 Porsche Panamera mostly succeeds in being an excellent large fastback sedan.
