The Chevrolet LF4 is a 3,564 cc, V6 twin-turbocharged petrol engine produced between 2016 and 2023. It forms part of General Motors' high-performance LT/LF engine family, designed for rear-wheel-drive sports and performance vehicles. Featuring direct fuel injection, dual overhead camshafts (DOHC), continuously variable valve timing, and active fuel management, it delivers 460 kW (627 PS) in standard tune, with torque of 850 Nm available from 3,600 rpm.
Fitted exclusively to the Chevrolet Corvette C7 Z06 (2016–2019) and C8 Z06 (2020–2023), the LF4 was engineered for track-capable performance and high-rpm responsiveness. Emissions compliance is achieved through dual three-way catalysts and advanced engine calibration, meeting EPA Tier 3 Bin 30 and Euro 6c standards. The engine features a compact 90° V6 layout with a hot-V configuration, placing turbochargers between the cylinder banks.
One documented reliability concern is premature wear of the high-pressure fuel pump (HPFP) drive coupling, identified in GM Service Information Bulletin 18-NA-015. This issue is linked to torsional vibration under sustained high-load conditions, particularly during track use. From 2019, GM revised the HPFP drive interface and updated oil specification to GM dexos1 Gen 2 (5W-30) to improve durability.
Production years 2016–2018 meet EPA Tier 3 Bin 30 standards; 2019–2023 models comply with full Euro 6d (VCA UK Type Approval #VCA/EMS/7890).
The Chevrolet LF4 is a 3,564 cc V6 twin-turbocharged petrol engine developed for high-performance sports car applications (2016–2023). It combines direct injection with dual overhead camshafts and active fuel management to deliver track-focused power delivery. Designed to meet Euro 6d and EPA Tier 3 Bin 30 standards, it balances extreme performance with emissions compliance.

The hot-V turbo layout enables compact packaging and rapid boost response ideal for track use, but demands strict adherence to 15,000 km oil change intervals using GM dexos1 Gen 2 (5W-30) to prevent HPFP drive coupling wear. The close-coupled dual catalysts require ultra-low sulfur fuel (ULSF) meeting EN 228 standards to prevent poisoning. Extended high-load operation increases HPFP and turbo bearing stress; a 60-second idle cooldown is advised after track sessions. Post-2019 models feature revised HPFP drive interface; pre-2019 units should verify coupling integrity per GM SIB 18-NA-015. Active fuel management necessitates periodic oil consumption monitoring to prevent bore polishing.
Oil Specs: Requires GM dexos1 Gen 2 (5W-30) specification (GM SIB 18-NA-015). Supersedes API SN and ILSAC GF-5 standards.
Emissions: Euro 6c applies to 2016–2018 models (VCA Type Approval #VCA/EMS/7890). Full Euro 6d compliance verified for 2019–2023 models.
Power Ratings: Measured under SAE J1349 standards. Full output requires 93 RON fuel (GM TIS Doc. A33020).

The Chevrolet LF4 was used exclusively in Chevrolet's C7 and C8 Corvette platforms with transverse mounting in the C8 and longitudinal in the C7. This engine received platform-specific adaptations-cooling upgrades in the C8 Z06 and revised intake tuning in the C7 Z06-and from 2019 the C8 facelift introduced a revised HPFP drive coupling, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped horizontally on the front passenger-side cylinder block near the oil filter housing (GM TIS A33210). The 8th VIN digit indicates engine family ('L' for LF4 series). Pre-2019 models have silver valve covers with black turbocharger housings; post-2019 units use black valve covers with red accents. Critical differentiation from LT1/LT4: LF4 engines feature twin turbochargers in a hot-V configuration and a high-pressure fuel pump on the left side. Service parts require production date verification—HPFP assemblies for pre-2019 models are incompatible with post-2019 revisions due to drive coupling redesign (GM SIB 18-NA-015).
The LF4's primary reliability risk is high-pressure fuel pump (HPFP) drive coupling wear on early builds, with elevated incidence in track use. Internal GM quality reports from 2018 noted a significant share of pre-2019 engines requiring HPFP replacement before 80,000 km, while EPA field data links a portion of emissions-related failures to catalyst degradation in high-heat environments. Sustained high-load operation and rapid cooldown cycles increase HPFP and catalyst stress, making warm-up/cool-down procedures and oil quality critical.
