New Car: 2014 Mercedes S63 AMG

Ask Audi why there’s no RS8, or BMW why there’s no M7, and the answers inevitably will include: There’s not enough of a market for such a car, or, This is not a priority for us, or even, Those customers care about comfort, not performance. Thankfully, there is one automaker that continues to think otherwise: Mercedes-Benz. For the better part of the past decade, the S-class lineup has been crowned by not one, but two high-performance AMG derivatives. We’re told that three to five percent of S-class sales are S63s and one to two percent are S65s, which tells us that there is enough of a business case to satiate Mercedes. And when you consider that competition in the luxury segment, more than anywhere else, is still about bigger and better, Benz aficionados will take pleasure in the fact that the 2014 S63 AMG is the most powerful vehicle in its class—at least until the sheets come off the S65. 

The new S63 keeps its M157 5.5-liter twin-turbo V-8, but it gets a significant power boost. Output is up 49 horses over its predecessor to 585, served up at 5500 rpm, and torque jumps up 74 lb-ft for a total of 664, available from 2250 rpm. Thrust is fed exclusively through all four wheels—other markets have the option of rear-wheel drive—via a seven-speed automatic. Despite the addition of 4MATIC, AMG says weight is down versus the outgoing model, and improved aerodynamics further enhance performance and efficiency. 

The result is a sprint from standstill to 62 mph that, Benz says, takes an even four seconds—a number we feel is plenty conservative considering the last S63 we tested required just 4.1 seconds to accomplish the feat. Top speed is governed at 155 mph, although raising that number to 186 can be achieved via a factory-specified upgrade. The exhaust note should leave little to be desired, as Mercedes’ "logic-controlled" exhaust flaps ensure a minimum of compliance with regulations. The automaker says that the new S63 achieves 22.8 mpg in the ever-optimistic European cycle, but we’d be remiss if we didn’t point out that the brand frequently comes close to replicating its official figures in real-world consumption.
