Chronology
Predecessor Nissan 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.

VR30 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.

Production

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

VR35 series

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

Designated the VR38DETT by Nissan, the engine is used from 2007Present 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]

Since 2011, all VR38DETTs produced came with a red top engine cover in the GT-R 2012 Nissan GT-R engine.jpg

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]

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. [15] [16]

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

The GM Ecotec engine, also known by its codename L850, is a family of all-aluminium inline-four engines, displacing between 1.2 and 2.5 litres. Confusingly, the Ecotec name was also applied to both the Buick V6 Engine when used in Holden Vehicles, as well as the final DOHC derivatives of the previous GM Family II engine; the architecture was substantially re-engineered for this new Ecotec application produced since 2000. This engine family replaced the GM Family II engine, the GM 122 engine, the Saab H engine, and the Quad 4 engine. It is manufactured in multiple locations, to include Spring Hill Manufacturing, in Spring Hill, Tennessee, with engine blocks and cylinder heads cast at Saginaw Metal Casting Operations in Saginaw, Michigan.
