Chronology
PredecessorNissan VQ engine, Nissan RB engine

The VR is a series of twin-turbo DOHC V6 automobile engines from Nissan with displacements of 3.0, 3.5, and 3.8 L. 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.

VR30DDTT

[edit | edit source]

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 or two water pumps for the 300 hp (224 kW) and 400 hp (298 kW) variants, respectively
  • Electronically controlled variable displacement oil pump
  • Intake: electronic variable valve timing Control (VTC)
  • Exhaust: hydraulic continuously variable VTC
  • Fuel system: direct injection

Production

[edit | edit source]

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

[edit | edit source]
VR35DDTT

The VR35DDTT was announced in March 2024 for the third-generation Infiniti QX80. It is also used in the related Nissan Patrol/Armada.[8] It is a larger version of the VR30DDTT and replaces the 5.6-liter VK56 V8 engine in Nissan's largest automobiles. A bore and stroke of 86 mm × 100.2 mm (3.39 in × 3.94 in) makes for an overall displacement of 3.5 L (3,492 cc; 213.1 cu in).[9]

VR38DETT

[edit | edit source]

Designated the VR38DETT by Nissan, the engine was originally developed and used from 2007–2025 in the Nissan GT-R.[10] It is the first engine produced in Nissan's VR series, and the most powerful production engine produced by a Japanese manufacturer.[11]

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.[12]

Since 2011, all VR38DETTs produced came with a red top engine cover in the GT-R

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).[13]

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

VR38DETT NISMO Engine Tuning Menu Concept (2016)

[edit | edit source]

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.[18][19]

Production

[edit | edit source]

The engines were hand built by only a total of nine specially trained mechanics called "Takumi Craftsmens" since its introduction in 2007, on a special line at Nissan's Yokohama plant and their names are badged on each engine.[20][21][22][23][24]
