2014 Mercedes S63 AMG: 577 HP And 3.7s 0-60 Performance

The 2014 Mercedes-Benz S63 AMG transforms the iconic S-Class into a high-performance beast, blending effortless luxury with explosive acceleration. Powered by a twin-turbocharged 5.5-liter V8 engine producing 577 horsepower and a staggering 664 pound-feet of torque, this sedan catapults from 0 to 60 mph in as little as 3.7 seconds, outpacing many supercars while maintaining the poise of a flagship limousine.

Engineering Marvel Under the Hood

At the heart of the S63 AMG lies the M157 twin-turbo V8, an evolution of previous AMG powerplants with significant gains over its predecessor: 14 more horsepower and 74 additional pound-feet of torque. This engine pairs seamlessly with a 7-speed automatic transmission and standard 4MATIC all-wheel drive, which biases 67% of power to the rear wheels for a rear-drive feel without sacrificing traction.

Mercedes claims a 0-60 mph time of 3.9 seconds, but real-world testing shatters this mark. Independent evaluations clocked it at 3.7 seconds, with a quarter-mile run in 12.1 seconds at 115.5 mph—nearly a full second quicker than the prior rear-drive model and the less potent S550 4MATIC. Mid-range punch from 35-80 mph feels missile-like, thanks to the torque-rich delivery that avoids turbo lag.

Dynamic Handling and Suspension Mastery

Despite its nearly 5,000-pound curb weight (around 4,914-4,943 lbs), the S63 AMG defies physics with agile handling. The AMG-tuned adaptive air suspension offers Comfort and Sport modes, adjusting damping on the fly to minimize body roll while preserving a compliant ride. In Comfort, a front stereo camera scans ahead to preemptively soften for bumps; Sport mode firms everything up for sharper responses.

Steering provides meaty feedback, though some note it can feel slightly numb in Comfort. Massive ventilated compound brakes haul the sedan to a stop from 60 mph in 100 feet, competitive with rivals like the Jaguar XJR. The 4MATIC system excels in wet conditions, delivering inexhaustible traction on rain-slicked roads without torque steer.

This table highlights how the S63 edges out luxury sport sedans in acceleration and stopping power, with handling on par or better.

Luxury Beyond Expectations

Inside, the S63 AMG elevates S-Class opulence with AMG-specific touches like sport seats, carbon-fiber trim, and an optional Burmester High-End 3D audio system that delivers immersive sound—its metal grilles proudly labeled for distinction. The cabin boasts flawless leather, wood accents, and vast space for four adults, with rear passengers enjoying reclining seats and entertainment options.

Technology abounds: massaging seats, ionized air purification, and a COMAND infotainment system, though its complexity can overwhelm. The ride remains supple over flawed surfaces, compensating for Sport mode’s firmness with buttery power delivery.

Real-World Driving Insights

Testers praise the S63’s versatility—from autobahn cruises at triple-digit speeds to low-speed luxury. However, minor quirks emerge: low-speed cornering can produce screeching tire noise due to AWD and massive tires, akin to binding in older 4WD systems. Fuel economy lags at 17.4 mpg combined (45% city/55% highway), reflecting its performance focus.

In Sport mode, the chassis stiffens for precise inputs, employing brake-based torque vectoring and a rear-biased AWD for playful dynamics. The AMG sport exhaust provides a refined growl—authoritative yet not harsh.

Pros and Cons at a Glance

• Pros: Explosive power and torque; superior handling for size; luxurious, spacious interior; advanced suspension tech.
• Cons: Sky-high price (~$140k-$160k); thirsty engine; intricate controls; occasional low-speed AWD quirks.

Competitive Landscape

The S63 AMG dominates rivals like the Jaguar XJR, Audi S8, and BMW Alpina B7 in raw speed and smoothness. Its AWD upgrade addresses prior rear-drive limitations, making it a year-round missile. While not a pure driver’s car like a BMW M3, it’s unmatched for being chauffeured at high speeds in supreme comfort.

Pricing and Ownership Considerations

Base price starts at $140,425, ballooning with options like the $6,400 Burmester system. Consumer ratings average 4.5/5 for performance and quality, though value scores lower due to cost. Maintenance suits high-end ownership, with AMG’s reputation for durability.
