The 2025 and 2026 Mercedes S63 AMG Specs show a plug-in hybrid luxury sedan that pairs a handcrafted 4.0-liter V8 biturbo with a rear-mounted electric motor for output that rivals exotic supercars. Here is every specification that matters, from the hybrid powertrain and performance numbers to pricing and real-world efficiency.

S63 AMG Hybrid Powertrain Specs

The combustion side is a handcrafted 4.0L V8 biturbo displacing 3,982 cc with DOHC 32-valve valvetrain and variable valve timing on both intake and exhaust sides. It produces 603 hp and 664 lb-ft on premium unleaded fuel, with peak torque arriving at a relatively low 2,500 rpm and holding through 4,500 rpm. The rear-mounted 140 kW (188 hp) permanent-magnet synchronous motor adds 236 lb-ft of instant electric torque available from rest, bringing total system output to 791 hp at 5,500–6,500 rpm and a combined 1,055 lb-ft.

The P3 hybrid layout places the electric motor entirely at the rear, with its own 2-speed automatic transmission while the V8 uses the AMG SPEEDSHIFT MCT 9G. The result is AMG Performance 4MATIC+ all-wheel drive with a center limited-slip differential: the front axle is driven by the engine, the rear by both the engine and electric motor. This setup delivers full torque from low rpm without lag, and the electric motor fills any gap before the turbos spool. Only one trim is offered for the US market.
