Last year, Mercedes added the S63 AMG to the range, which complements the other AMG model: the Bentley-battling S65. Whereas the S65—which boasts 604 hp and 738 ft-lbs of torque—is adept at consuming interstate and blurring the landscape in supersonic fashion, the lighter S63 is aimed at the V-8 enthusiast more apt to relish a race-inspired 518-hp 6.2-liter engine with a 7-speed automatic and steering wheel paddle shifters. But the 2010 model year ushered in the S400 Hybrid Sedan for those more interested in reservation rather than performance. As the first series production sedan in the world to utilize lithium-ion battery technology, the S400 produces 295 hp while remaining 26 percent more fuel efficient than the S550. Lastly, anyone who wants a little more oomph but does not wish to spend six figures on one of the performance-oriented AMG cars, or for that matter, the über-luxurious V-12 S600, will appreciate the relative sanity of the entry-level S550; with 382 hp, the V-8-powered S-Class sedan offers a practical but no less prestigious alternative.
Pros: With five different power train options, what’s not to like?
Cons: The exterior packaging is a bit blasé.
