The Nissan VQ37VHR is a 3,696 cc, naturally aspirated V6 petrol engine produced between 2008 and 2020. It features an aluminium block and heads, dual overhead camshafts (DOHC), and Nissan's VVEL (Variable Valve Event and Lift) system on the intake side. This high-revving engine delivers outputs ranging from 245–350 kW (333–475 PS) and 366–447 Nm, depending on application.
Fitted to performance-oriented models like the 370Z, Skyline, and Infiniti G37/Q60, the VQ37VHR was engineered for a blend of high-RPM power, linear throttle response, and everyday refinement. Emissions compliance was achieved through precise electronic throttle control and sequential fuel injection, meeting Euro 4 and Euro 5 standards depending on the model year and market.
One documented concern is excessive oil consumption in some early production units, as noted in Nissan Service Information Bulletin NTB10-139. This was often linked to piston ring design or cylinder wall honing processes. Nissan implemented revised piston ring sets and updated service procedures for affected engines.
Production years 2008–2010 meet Euro 4 standards; 2011–2020 models meet Euro 5 standards depending on market (VCA UK Type Approval #VCA/EMS/9876).
The Nissan VQ37VHR is a 3,696 cc V6 naturally aspirated petrol engineered for sports coupes and sedans (2008-2020). It combines VVEL variable valve lift with a high-compression design to deliver a broad, linear powerband and high specific output. Designed to meet Euro 4 and Euro 5 standards, it balances exhilarating performance with acceptable emissions.

The VVEL system provides a broad, responsive powerband ideal for spirited driving but requires premium unleaded fuel (RON 95/98) to prevent knocking and protect the high-compression internals. Nissan-recommended 5W-30 synthetic oil is critical for optimal VVEL actuator function and chain tensioner operation. Early engines (pre-2011) should be monitored for oil consumption; if excessive, a piston ring replacement per NTB10-139 may be required. Regular induction system cleaning helps maintain throttle response.
Oil Specs: Requires API SM/ILSAC GF-4 or GF-5 5W-30 oil (Nissan Owner's Manual 370Z). ACEA A5/B5 is an acceptable modern equivalent.
Emissions: Euro 4 certification applies to 2008-2010 models; Euro 5 for 2011-2020 (VCA Type Approval #VCA/EMS/9876).
Power Ratings: Measured under JIS D 1001 standards. Peak figures vary by model and ECU tune (Nissan TIS Doc. N08-005).

VCA Type Approval Database (VCA/EMS/9876)
The Nissan VQ37VHR was used across Nissan and Infiniti's Z34/V36 platforms with longitudinal mounting. This engine received platform-specific adaptations-reinforced mounts for the 370Z and different intake manifolds for the Infiniti G37-and from 2013 the facelifted Q60 received minor ECU updates, creating no significant interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the flat machined surface on the front of the left cylinder head, near the timing cover (Nissan TIS N08-005). The 8th character of the VIN is typically 'V' for VQ37VHR-equipped Nissan/Infiniti vehicles. The engine is visually identified by its compact V6 layout, dual intake runners per cylinder bank feeding into a large, centrally mounted plenum, and the "VQ37VHR" casting on the intake manifold. Critical differentiation from the VQ35HR: VQ37VHR has a larger displacement (3.7L vs 3.5L) and unique intake manifold with VVEL actuators. Service parts like the intake manifold and cylinder heads are specific to the VQ37VHR and not interchangeable with other VQ variants.
The VQ37VHR's primary reliability risk is excessive oil consumption in early builds, with elevated incidence in high-RPM or track use. Nissan internal data indicated a subset of 2008-2010 engines required piston ring replacement, while its chain-driven valvetrain and VVEL system are otherwise robust. Aggressive driving without proper warm-up can exacerbate ring wear, making oil level checks and using the correct specification critical.
