2018-2022 BMW M8 M5 F90 S63M 4.4L V8 COMPLETE ENGINE GUARANTEED 28K MILES

BMW M8 (F92/F93), M5 (F90) S63M 4.4L V8 Engine (2018-2022)

Engine Model:

• S63B44T4 (also known as S63M)
• This is a high-performance twin-turbocharged V8 engine used in BMW’s flagship M models like the M8 and M5.

Engine Specifications:

1. Displacement:
   • 4.4 liters (4,395 cc)
2. Configuration:
   • V8 engine with a 90-degree V-angle, featuring twin-turbocharging technology.
   • The engine is part of BMW’s hot-V design, meaning the turbochargers are located between the cylinder banks for quicker response and reduced turbo lag.
3. Induction System:
   • Twin-scroll turbochargers (one for each cylinder bank), integrated into the hot-V for enhanced efficiency and throttle response.
   • Boost pressure is around 1.5 bar (21.75 psi), allowing for powerful acceleration and top-end performance.
4. Power Output:
   • 600 hp (447 kW) @ 6,000 rpm for the standard M5 and M8 models.
   • 617 hp (460 kW) @ 6,000 rpm for the M5 Competition and M8 Competition variants.
5. Torque:
   • 553 lb-ft (750 Nm) of torque available from as low as 1,800 rpm up to 5,600 rpm, offering excellent low-end grunt and mid-range power for rapid acceleration.
6. Redline:
   • The engine can rev up to a maximum of 7,200 rpm, providing a broad powerband.
7. Compression Ratio:
   • 10.0:1, optimized for turbocharging while balancing power and fuel efficiency.

Engine Components:

1. Fuel System:
   • Direct Fuel Injection (High-Precision Injection): Fuel is injected directly into the combustion chambers at high pressure, ensuring better combustion, improved fuel efficiency, and power.
   • Dual high-pressure fuel pumps help maintain a consistent fuel supply even under high-performance driving conditions.
2. Valvetrain:
   • Double Overhead Camshafts (DOHC) with variable valve timing (VANOS) and Valvetronic technology.
   • Valvetronic adjusts the intake valve lift, improving throttle response and efficiency by controlling the amount of air entering the engine without relying on a traditional throttle body.
3. Turbochargers:
   • The twin-scroll turbochargers are positioned inside the “hot V” to minimize the distance exhaust gases travel, thereby reducing turbo lag and increasing responsiveness.
   • These turbochargers are water-cooled to maintain optimal performance during high loads and extreme conditions.
4. Cooling System:
   • Features a sophisticated liquid-cooling system with two intercoolers (one per turbo), additional radiators, and a high-capacity oil cooler.
   • An electric water pump helps cool the turbochargers after engine shutdown, reducing wear on the turbo components.
5. Exhaust System:
   • Sport-tuned exhaust system with electronically controlled exhaust flaps that adjust based on driving mode for a more aggressive sound during spirited driving and quieter operation when in comfort mode.
   • Exhaust flaps open in Sport and Sport+ modes, enhancing the engine note.
6. Lubrication System:
   • Dry-sump lubrication ensures consistent oil flow even during high lateral forces (cornering, acceleration, and braking) for track-ready reliability.
   • Includes an oil scavenging pump and oil reservoir located away from the crankcase, providing better lubrication in dynamic driving conditions.

Performance:

1. Acceleration:
   • The engine provides 0-60 mph acceleration in as little as:
     • 3.2 seconds for the M5.
     • 3.1 seconds for the M8 Coupe.
     • 3.0 seconds for the M5 Competition and M8 Competition variants.
2. Top Speed:
   • 155 mph (electronically limited).
   • Can be increased to 189 mph with the optional M Driver’s Package.
3. Power Delivery:
   • Strong low-end torque for swift acceleration and smooth power delivery through the entire rev range, making the S63M suitable for both street and track use.

Engine Weight:

• The S63M engine weighs approximately 617 lbs (280 kg). The relatively low weight for such a powerful engine helps improve the vehicle’s overall handling and agility.

Technological Features:

1. M TwinPower Turbo Technology:
   • BMW’s proprietary system that combines high-performance twin-scroll turbocharging with High-Precision Injection, Valvetronic, and VANOS variable valve timing to enhance both efficiency and performance.
2. Engine Control:
   • Managed by BMW’s Digital Motor Electronics (DME), which coordinates fuel injection, ignition timing, and turbocharging to ensure optimal performance across various driving conditions.
   • Customizable driving modes (Comfort, Sport, and Sport+) allow the driver to tailor engine response, shift points, and throttle sensitivity based on driving preferences.

Fuel Efficiency and Emissions:

• The S63M engine is designed to meet Euro 6 and US EPA emissions standards.
• Fuel consumption for the BMW M5 and M8 models ranges between 16-22 mpg depending on driving style and conditions, with higher efficiency in highway driving due to the advanced turbocharging system.

Mileage:

• 28,000 miles: This specific engine is guaranteed to have only 28,000 miles, indicating that it has relatively low usage and is in excellent condition for future use.

Warranty and Reliability:

• This engine’s low mileage (28K miles) means that it has plenty of remaining life and is suitable for both replacement and performance upgrades.
• Certified Used: The engine might come with guarantees or warranties depending on the seller or dealer, ensuring reliable operation.

Summary of Benefits:

• High Performance: The S63M engine is engineered for peak performance with exceptional power and torque, providing explosive acceleration and smooth power delivery.
• Guaranteed Low Mileage: With only 28,000 miles, this engine is relatively new and in good condition, offering a long lifespan for continued use.
• Ideal for Replacement or Upgrade: This engine is perfect for those looking to replace a worn engine or upgrade a vehicle with a low-mileage, high-performance powertrain.
• Track-Ready Engineering: The S63M engine’s advanced cooling, lubrication, and turbocharging systems make it capable of handling track use while maintaining everyday drivability.
