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.

The VQ is a family of V6 automobile petrol engines developed by Nissan and produced in displacements varying from 2.0 L to 4.0 L. Designed to replace the VG series, the all-aluminium 4-valve per cylinder DOHC design debuted with Nissan's EGI/ECCS sequential multi-point fuel injection (MPFI) system. Changes from the VG engine include switching to a timing chain from a timing belt, and relocating the water pump from the outside of the engine to inside the timing cover where the pump is driven by the timing chain. Later versions featured various improvements, such as variable valve timing, and NEO-Di designated VQ engines replace MPFI with direct fuel injection.
