⚙️ Engine Specifications

Engine Options Common:

V6 Twin-Turbo (3.0L) and V8 Twin-Turbo (3.8L - often Ferrari-derived). Earlier generations also featured naturally aspirated V8s (4.2L, 4.7L).

Horsepower Torque Ranges:

Horsepower typically ranges from 400hp to over 500hp, with torque figures exceeding 400 lb-ft, depending on the specific engine and model year. For example, the 3.8L Twin-Turbo V8 in later models often produced around 523 hp and 524 lb-ft of torque.

Fuel System:

Direct injection, twin-turbocharged induction for most modern variants.

Oil Type Capacity Example:

Specific to engine variant, e.g., for a 3.0L V6 Twin-Turbo, it might require synthetic 5W-30 or 0W-40 API SN certified oil, with a capacity around 7.5-8.0 liters. Always consult manual for precise specifications.

Coolant Type:

Ethylene glycol based coolant, often a specific long-life formulation. Capacity varies by engine, typically 9-12 liters.

Engine Codes:

Examples might include F136 (for Ferrari-derived V8s), F140 (if applicable), and specific Maserati codes for V6 variants.
