Nissan VR 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 seriesVR30DDTTAnnounced 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]
Applications:
ProductionProduction of the VR30DDTT engine began in 2016 at the powertrain plant in Iwaki, Fukushima.[5][6][7] VR35 seriesVR35DDTTThe 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] Applications:
VR38 seriesVR38DETTDesignated 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] Other pertinent features of the VR38DETT include:
