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…
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 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.
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.

The most common questions about engine codes, what they mean, how to find them and how this database works
The VQ37VHR is generally very reliable long-term, especially post-2011 models where the oil consumption issue was largely resolved. Its chain-driven timing system is robust and designed to last the engine's life. Key to longevity is using the correct 5W-30 synthetic oil, premium fuel, and addressing any VVEL or ignition coil issues promptly. With proper care, these engines can easily exceed 300,000 km.
The most common documented issue is excessive oil consumption in early (2008-2010) engines. Other frequent problems include failures of the VVEL solenoids/actuators causing performance loss, ignition coil failures leading to misfires, and oil leaks from the valve cover gaskets. These are well-covered in Nissan service information.
The VQ37VHR was primarily used in the Nissan 370Z/Fairlady Z (2008-2020) and the Nissan Skyline 370GT/RS (2008-2019). It was also used extensively in Infiniti models, including the G37 (2008-2013) and Q60 (2014-2020) coupes, sedans, and convertibles.
Yes, the VQ37VHR responds well to tuning. Basic ECU remaps can yield 20-30 kW gains. More significant power increases require bolt-on modifications like performance intakes, exhausts, and camshafts. The engine's internals are strong, but pushing beyond 300 kW reliably often requires forged components. Forced induction (supercharger/turbo) kits are available for extreme power.
Fuel economy is moderate for its performance. Expect around 12-14 L/100km (20-24 mpg UK) in mixed driving for a 370Z. Highway cruising can yield 9-10 L/100km (28-31 mpg UK), while aggressive driving or track use can easily push consumption to 18 L/100km (16 mpg UK) or higher.
Yes. The Nissan VQ37VHR is an interference engine. This means if the timing chain were to fail or jump timing (an extremely rare event), the pistons would collide with the open valves, causing severe internal engine damage. This underscores the importance of using the correct oil to ensure chain tensioner function.
Nissan specifies a 5W-30 synthetic oil meeting API SM/ILSAC GF-4 or GF-5 standards. Using a high-quality, full-synthetic 5W-30 is crucial for protecting the VVEL system and ensuring proper lubrication of the timing chain tensioners. Regular oil changes (every 10,000 km or 6 months) are recommended.
