7 of 10
Large sedan: Mercedes-Benz S550
Starting price: $86,700
Power: 382-hp V-8
2nd place : Maserati Quattroporte Automatic
3rd place: Lexus LS 600h L

Mercedes is masterful at crafting top-flight luxury sedans, and this latest edition of its flagship sets a new gold standard. The S550, although not as powerful as the super-high performance 518-hp S63 AMG, strikes the perfect balance between power (382 hp), space (109.4 cu. ft. of passenger space vs. 95.8 average for the competition), and relative value (the S63 AMG starts at $127,000).

Throw in the luxury-hotel feeling of the interior -- complete with concierge-like electronic systems -- and it's easy to see why Mercedes still owns this segment.

NEXT: Crossover/Wagon: Lexus RX400h AWD
