The Mercedes‑AMG S 63 E PERFORMANCE (commonly called the Mercedes‑Benz S63 or AMG S63) is the high‑performance hybrid version of the S‑Class: a flagship luxury sedan that combines supercar‑like acceleration with first‑class comfort and technology. It sits near the top of Mercedes’ range as the ultimate blend of grand‑touring luxury and brute‑force performance.

Grand‑touring luxury sedan with four doors

The S63 is a four‑door, five‑seat luxury sedan built on the long‑wheelbase S‑Class platform, with a formal, imposing profile, huge rear doors, and a very low boot lip that makes loading and shipping easier. It offers around 500–550 litres of boot space (≈17–19 ft³)—enough for serious luggage while still keeping a sleek, low roofline. The interior emphasizes first‑class levels of noise‑isolation, air‑suspension comfort, and rear‑seat opulence, with plush materials, multi‑zone climate, massaging seats, and extensive sound‑deadening.

4.0‑litre V6 hybrid powertrain (E PERFORMANCE)

The current S63 uses a 4.0‑litre twin‑turbo V8 (M177) working with a rear‑axle electric motor, plus a relatively small lithium‑ion battery pack in the E PERFORMANCE layout. Key specs:

• 791 hp combined (≈270 kW from the V8 + 188 hp from the motor),

• 1,055 lb‑ft (≈1,430 Nm) of torque,

• 0–100 km/h (0–62 mph) in about 3.0–3.3 seconds, with a limited top speed around 290 km/h (180 mph).

Power is sent through a 9‑speed AMG Speedshift MCT automatic and all‑wheel drive (4MATIC+), giving explosive straight‑line performance while still allowing the car to drive short distances in electric‑only mode for smoother, quieter city operation. Official fuel‑economy figures are around 45–47 MPG‑e city and 50–53 MPG‑e highway (≈19–22 km/l‑equivalent) in EV‑plus‑hybrid operation.

Supercar‑like dynamics with S‑Class refinement

The S63’s chassis is tuned to handle its massive power while retaining S‑Class comfort:

• AMG‑specific suspension and adaptive dampers,

• Performance‑oriented steering and huge brakes (often carbon‑ceramic option),

• Rear‑axle torque vectoring and rear‑wheel‑steer on many trims,

The result is a planted, neutral feel in corners with strong grip and minimal body roll, yet it remains remarkably calm and isolated on bad roads. The E PERFORMANCE system also adds an electric “torque‑fill” that smooths out turbo lag, making throttle responses feel almost instant.

Tech‑rich, ultra‑luxury cabin

Inside, the S63 mirrors the S‑Class’ flagship tech:

• Dual curved display (12.3‑inch instrument cluster plus 14.4–17‑inch central screen) with AMG‑specific graphics,

• MBUX infotainment with voice control, augmented‑reality navigation, Apple CarPlay/Android Auto, and advanced connected‑services,

• Executive rear‑seat packages with reclining seats, fold‑out tables, rear screens, and mood‑lighting,

• Drive‑assistance suite including adaptive cruise, lane‑keeping, night‑vision, 360‑camera, and more.

Pricing and who it suits

The 2026 AMG S 63 E PERFORMANCE typically starts around $187,000–$190,000 USD MSRP, with well‑optioned cars often reaching $210,000–$230,000 USD. In used markets, earlier W222 S63 AMG sedans trade roughly in the $70,000–$120,000 USD band, depending on year, mileage, and condition.

The S63 is ideal for wealthy buyers who want a low‑profile super‑sedan: a car that can outrun many sports cars in a straight line while still offering limo‑grade rear comfort, refinement, and everyday usability—perfect as a flagship executive sedan, grand‑tourer, or high‑status family flagship.
