The VR is a series of twin-turbo DOHC V6 automobile engines from Nissan with displacements varying from 3.0 to 3.8 L (2,997 to 3,799 cc). An evolution of the widely successful VQ series, it also draws on developments from the VRH, JGTC, and Nissan R390 GT1 Le Mans racing engines.

DDTT series

VR30DDTT

Announced by Infiniti on December 15, 2015 the VR30DDTT[2] was first made available in the Infiniti Q50 sedan, followed by the Infiniti Q60 coupé a year later. Both platforms come in a 300 and 400 hp (224 and 298 kW) version.[3] It is on the Ward's 10 Best Engines list for 2017 and 2018.

Features:[4]

• Aluminium block with arc sprayed mirror coating to cylinder bores
• Aluminium cylinder head
• Lightweight resin intake and lower oil pan
• Compact twin direct-mount turbos with integrated exhaust manifold and electronic wastegate actuator
• Twin water-to-air charge coolers with one 300 hp (224 kW)/two 400 hp (298 kW) water pumps
• Electronically controlled variable displacement oil pump
• Intake: electronic Variable valve timing Control (VTC)
• Exhaust: hydraulic continuously variable VTC
• Fuel system: direct injection

Applications:

Years	Model	Power output
2016–present	Infiniti Q50	300–400 hp (224–298 kW)
2017–present	Infiniti Q60	300–400 hp (224–298 kW)
2019–present	Nissan Skyline	300–400 hp (224–298 kW)
2022–present	Nissan Z	400 hp (298 kW)

Production

Production of the VR30DDTT engine began in 2016 at the powertrain plant in Iwaki, Fukushima, Japan.[5][6][7]

DETT series

VR38DETT

Designated the VR38DETT by Nissan, the engine was used from 2007–2022 in the Nissan GT-R[8] and the limited production Nissan Juke-R.

The VR38DETT featured 24 valves controlled by dual overhead camshafts (2 per cylinder head) with variable valve timing on the intake only. The block is cast aluminium with 0.15 mm (0.0059 in) plasma-sprayed cylinder liner bores. This coating provides a hard protective layer for the piston rings to slide on as the piston moves up and down during its power cycle. The turbine housings for the two IHI turbochargers are integrated into the exhaust manifolds to decrease weight and bolster vehicle balance. The engine also features a pressurized lubrication system controlled thermostatically. The VR38DETT is equipped with a feedback control system that changes air fuel ratio depending on the engine load which has a significant effect on reducing the fuel consumption.[9]

Fully equipped with the first set of catalytic converters, turbos, all of the engine driven accessories, front differential assembly, and turbo outlet pipes, the engine weighed 608 lb (276 kg).[10]

Other pertinent features of the VR38DETT include:

• Continuously variable valve timing control system (CVTCS) on intake valves
• Aluminum cylinder block with high-endurance/low-friction plasma-sprayed bores
• Iridium-tipped spark plugs
• Electronic drive-by-wire throttle
• Multi port fuel injection
• Pressurized lubrication system with thermostatically controlled cooling and magnesium oil sump
• Fully symmetrical dual intake and low back-pressure exhaust system
• Secondary air intake system to rapidly heat catalysts to peak cleaning efficiency
• 50 State LEV2/ULEV

Applications:

Years	Model	Power output
2007–2022	Nissan GT-R	480–710 hp (358–529 kW)
2011	Nissan Juke-R (only 5 units were produced)	545 hp (406 kW)
2014	Infiniti Q50 Eau Rouge Prototype (Concept car)	560 hp (418 kW)
Racing:
2012–present	Nissan GT-R Nismo GT3	599 hp (447 kW)
2014–2021	Renault Sport R.S. 01	550 hp (410 kW)[11]
2017–2019	Ligier Nissan DPi	599 hp (447 kW)

VR38DETT NISMO Engine Tuning Menu Concept (2016)

It is a version of VR38DETT engine used in Nissan GT-R, with GT3-spec camshaft, connecting rod and connecting rod bolt, intercooler, intercooler piping, turbocharger, NISMO 1st and 2nd catalyzers, titanium muffler.

The engine was unveiled in 2016 Tokyo Auto Salon.[12][13]

Production

The engines are hand built by five specially trained mechanics called "Takumi Craftsmens" on a special line at Nissan's Yokohama plant and their names are badged on every GT-R engine. The cars are built at their Tochigi plant on a shared production line.[14][15][16][17][18]
