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…
Production years 2023–present meet Euro 6d standards .
The Ferrari 637 is a 2,992 cc 120° V6 twin-turbo petrol engine engineered for high-performance sports cars (2023–present). It combines hot-V turbo layout with plug-in hybrid electrification to deliver track-capable power delivery and agile throttle response. Designed to meet Euro 6d, it balances extreme performance with regulated emissions compliance.

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.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
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.

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.
