Maserati M156 Series Engine: High-Performance V6 Twin-Turbo Power
The Maserati M156 engine series is a high-performance V6 twin-turbocharged gasoline engine, mainly used in the Quattroporte, Levante SUV, and Ghibli executive sedan. It features an aluminum alloy block and cylinder head, direct fuel injection (GDI), and offers multiple power outputs, making it the core power source for Maserati’s modern high-performance models from the 2010s to the 2020s.
Core Features of the M156 Engine:
V6 Twin-Turbo: Equipped with twin turbochargers to provide ample power and quick response.
Direct Fuel Injection (GDI): Improves fuel efficiency and power output.
Aluminum Alloy Construction: Reduces engine weight and improves handling.
Power Variants: Offers different power levels to suit various models and customer needs (e.g., Quattroporte’s 257kW low-power version and 316kW high-power version).
Transmission Matching: Typically paired with the ZF 8HP 8-speed automatic transmission.
Main Applications and Performance (M156C Example):
Maserati Quattroporte: Low-power version (M156D) around 350 hp (257 kW), high-power version around 430 hp (316 kW), with strong torque.
Maserati Levante: Uses the same V6 engine series with multiple tuning options.
Maserati Ghibli: Entry-level models also feature this V6 engine.
The M156 series (including M156C/D) has been Maserati’s primary V6 engine for mid-to-large vehicles over the past decade, combining Italian high-performance tradition with modern turbocharging technology, and is a key pillar of Maserati’s high-performance luxury sedan and SUV lineup.
Global Markets for the M156C Engine
The M156C engine is mainly installed in Maserati models such as the Ghibli, Quattroporte, and GranTurismo, making its primary markets countries and regions with high demand for luxury vehicles:
Europe: Italy (Maserati’s home market), Germany, United Kingdom, France, Switzerland
North America: United States, Canada
Middle East: United Arab Emirates, Saudi Arabia, Qatar, and other high-end vehicle regions
Parts of Asia: Japan, Hong Kong, Taiwan, and select mainland Chinese cities with luxury car owners
What to Consider When Choosing an M156 Engine
Fuel Requirements:
The M156 engine is sensitive to fuel quality and requires high-octane gasoline (usually 95/98 RON or higher). Long-term use of low-quality fuel may affect:
Fuel injection system
Combustion stability
Turbo performance and carbon buildup
This engine is not suitable for low-grade fuel, making fuel quality an important part of long-term operating costs.
Maintenance Frequency:
Compared to ordinary family engines, the M156C requires a higher standard of maintenance, typical of performance engines:
Shorter oil change intervals
High-quality fully synthetic oil is recommended
Regular checks for ignition and intake systems
Neglecting proper maintenance can significantly increase long-term costs.
Routine Maintenance Costs:
Maintenance costs are higher than standard brand engines
Spare parts and labor costs are elevated
High technical requirements for mechanics, low tolerance for mistakes
For ordinary owners, maintenance costs are considered high-end, while commercial or professional workshops must have the necessary experience and supply chain to manage the engine effectively.
Common Issues and Maintenance Tips
The M156 engine, a classic AMG naturally aspirated V8 in models like the C63, also applies to similar high-performance tuning concepts in Maserati. Common problems and preventative measures include:
Camshaft and Valve Lifter Wear
- Symptoms: “Ticking” noise at cold start, may extend to hot engine with mileage, sometimes accompanied by power loss.
- Minor wear: Replace valve lifters; some components can be replaced individually.
- Severe wear: Replace camshaft and full valve lifter assembly; forged camshafts and improved lifters recommended.
- Prevention: Use OEM or certified oils, avoid prolonged high-RPM operation, follow oil change intervals.
Camshaft Timing Sprocket Pin Misalignment
- Symptoms: Around 100,000 km, engine may shake, power fluctuations, or trigger fault codes.
- Repair: Replace timing sprocket or upgraded gear piece, requires professional tools.
- Prevention: Regularly check timing system, avoid aggressive driving.
Valve Seat Cup Wear or Leakage
- Symptoms: Abnormal engine noise, reduced valve sealing, power loss, increased fuel consumption.
- Repair: Replace valve seat cups, check valve springs and lifters.
- Prevention: Use proper valve seals, avoid prolonged high-temperature operation.
Oil Pressure Abnormalities
Symptoms: Oil pressure warning, possible engine vibration, or power loss.
Repair: Check or replace oil pressure sensor, inspect oil pump and passages.
Prevention: Regular oil pressure monitoring, use high-quality oil.
Summary: M156 engine issues are mostly related to high-load operation and component wear. Repairs should use genuine or certified parts, while preventative maintenance emphasizes attention to detail and driving habits.
