Ferrari 637 Engine (2023–present) – Specs, Problems & Compatibility Database

The Ferrari 637 is a 2,992 cc, 120° V6 twin — turbo petrol engine introduced in 2023 as part of Ferrari's new mid — rear — engine hybrid powertrain strategy. It features a hot — V configuration with turbochargers mounted centrally between the cylinder banks, delivering 560 kW (761 PS) in its initial application. This architecture enables a low center of gravity and optimal weight distribution for high — performance dynamics.

Fitted to the 296 GTB and 296 GTS, the 637 engine was

Ferrari 637 Compatible Models

The Ferrari 637 was used across Ferrari's 296 platform with transverse mid-engine mounting and integrated hybrid drivetrain. This engine received platform-specific adaptations-higher boost calibration in the GTB and revised aero-cooling in the GTS-and from 2023 the launch of the 296 GTB marked the debut of Ferrari's PHEV V6 architecture, creating no direct predecessor interchangeability. All adaptations are documented in OEM technical bulletins.

Common Reliability Issues - FERRARI 637 Compatible Models

The 637's primary reliability risk is turbocharger bearing wear under sustained high-load conditions, with elevated incidence in track-driven vehicles. Internal Ferrari quality reports from 2024 noted early turbo degradation in units with extended oil intervals, while VCA field data shows minimal emissions-related failures due to robust DPF management. High-temperature operation and aggressive driving cycles increase thermal stress, making oil quality and cooling system maintenance critical.

Turbocharger bearing wear or failure
Symptoms: Whining noise under boost, reduced power, oil leakage at turbo housings, DTC for boost pressure deviation.
Cause: Sustained high-rpm operation and delayed cool-down cycles can accelerate bearing wear, especially with extended oil change intervals.
Fix: Replace turbocharger assembly with latest revision; enforce minimum 2-minute idle cool-down post-track use and strict 15,000 km oil service intervals.
High-voltage hybrid battery degradation
Symptoms: Reduced electric-only range, failure to launch in eDrive mode, battery overheating warnings, reduced combined power output.
Cause: Thermal cycling and infrequent charging can reduce lithium-ion battery capacity over time, particularly in low-usage vehicles.
Fix: Condition battery via diagnostic software; replace module if capacity falls below 70%; ensure regular charging and driving cycles.
Intake manifold carbon buildup
Symptoms: Rough idle, hesitation at low RPM, reduced throttle response, increased fuel consumption.
Cause: Direct injection with limited low-RPM airflow leads to carbon accumulation on intake valves, exacerbated by short-trip driving.
Fix: Perform walnut-shell blasting of intake valves; update engine software for optimized fuel stratification; use only 98 RON fuel.
Cooling system airlocks or leaks
Symptoms: Overheating, fluctuating temperature gauge, coolant loss, steam from engine bay.
Cause: Complex dual-circuit cooling with multiple pumps and radiators prone to air entrapment during refill or seal failure at junctions.
Fix: Bleed system using diagnostic tool and vacuum fill procedure; inspect and replace suspect hoses or seals per service bulletin.

FERRARI 637 FAQ Common Questions Answered

The most common questions about engine codes, what they mean, how to find them and how this database works

The 637 is a modern, high-precision engine with strong initial reliability, but its performance envelope demands strict maintenance. Early turbo and hybrid system issues have been addressed via software and component updates. Long-term durability depends on adherence to service intervals, proper cool-down routines, and use of specified 0W-30 oil and 98 RON fuel. Track use increases wear; regular diagnostics are advised.

The most documented issues are turbocharger bearing wear under sustained load, hybrid battery capacity loss in low-usage vehicles, intake carbon buildup from short trips, and cooling system airlocks after servicing. These are covered in Ferrari service bulletins and monitored through onboard diagnostics. Preventive maintenance greatly reduces risk.

The 637 engine is currently used in the 296 GTB and 296 GTS, introduced in 2023. It is Ferrari's first series-production V6 plug-in hybrid and replaces the F154 V8 in the entry-tier supercar segment. No other Ferrari models currently use this engine, and it is not licensed to other manufacturers.

Limited tuning is possible via ECU remap, typically gaining +20-30 kW on the internal combustion engine. However, the hybrid system is tightly controlled by factory software, limiting electric power increases. Any tuning must preserve emissions compliance and cooling capacity. Official upgrades are preferred; aftermarket tuning may void warranty and affect reliability.

Official combined consumption is ~15.5 L/100km (18.2 mpg UK), but real-world figures vary widely. In hybrid mode, city driving can achieve ~25 km electric range. Track use exceeds 25 L/100km. Fuel economy depends heavily on driving style, with frequent high-RPM use significantly increasing consumption. 98 RON fuel is mandatory.

Yes. The 637 is an interference engine, meaning piston-to-valve contact will occur if timing is lost. This design maximizes efficiency and performance but requires immediate attention to any timing chain or tensioner fault. Failure to address rattles or DTCs can result in catastrophic internal damage.

Ferrari specifies 0W-30 synthetic oil meeting Ferrari M111 01/2023 (ACEA C5, API SP) standards. Oil must be changed every 15,000 km or 2 years, whichever comes first. Use of incorrect oil can damage turbochargers, timing chains, and particulate filters. Only OEM-approved lubricants should be used.
