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.
Announced by Infiniti on December 15, 2015 the VR30DDTT 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. It is on the Ward's 10 Best Engines list for 2017 and 2018.
- 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
The VR38DETT features 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.
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
