The VR is a series of twin-turbo DOHC V6 automobile engines from Nissan with displacements of 3.0 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.
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.

Applications:
| Years | Model | Power output |
|---|---|---|
| 2016–present | Infiniti Q50 | 300–400 hp (224–298 kW) |
| 2017–2022 | Infiniti Q60 | 300–400 hp (224–298 kW) |

| 2022–present | Nissan Z | 400–420 hp (298–313 kW) |
Production of the VR30DDTT engine began in 2016 at the powertrain plant in Iwaki, Fukushima.[5][6][7]
The VR35DDTT was announced in March 2024 for the upcoming, third generation Infiniti QX80. It will also be used in the related Nissan Armada/Patrol.[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]
Applications:
| Years | Model | Power output | Torque | Market |
|---|---|---|---|---|
| 2024–present | Infiniti QX80 (Z63) | 336 kW (450 hp) at 5,600 rpm | 700 N⋅m (516 lb⋅ft) at 3,600 rpm | North America |
| 2024–present | Nissan Patrol (Y63) | 335 kW (449 hp) at 5,600 rpm | 698 N⋅m (515 lb⋅ft) at 3,600 rpm[8] | Australia |
Designated the VR38DETT by Nissan, the engine is used from 2007–Present in the Nissan GT-R[10] 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.[11]
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).[12]

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.[15][16]
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.[17][18][19][20][21]
