The naming convention originally adhered to the current trend of using a numeric designation derived from the engine's displacement, thus QX56 since the car has a 5.6 - liter engine . From the 2014 model year, the car was renamed the QX80, as part of Infiniti's model name rebranding . The new name carries no meaning beyond suggesting that the vehicle is larger than smaller models such as the QX60 . </P> <Table> <Tr> <Th_colspan="2"> First generation (JA60) </Th> </Tr> <Tr> <Td_colspan="2"> </Td> </Tr> <Tr> <Th_colspan="2"> Overview </Th> </Tr> <Tr> <Th> Also called </Th> <Td> Nissan Armada WA60 </Td> </Tr> <Tr> <Th> Production </Th> <Td> 20 January 2004--March 2010 </Td> </Tr> <Tr> <Th> Assembly </Th> <Td> Canton, Mississippi, United States </Td> </Tr> <Tr> <Th> Designer </Th> <Td> Masato Takahashi (2001) </Td> </Tr> <Tr> <Th_colspan="2"> Body and chassis </Th> </Tr> <Tr> <Th> Class </Th> <Td> Full - size luxury SUV </Td> </Tr> <Tr> <Th> Body style </Th> <Td> 5 - door SUV </Td> </Tr> <Tr> <Th> Layout </Th> <Td> Front engine, rear - wheel drive / four - wheel drive </Td> </Tr> <Tr> <Th> Related </Th> <Td> Nissan Titan TA60 Nissan Armada WA60 Nissan Frontier D40 Nissan Xterra N50 Nissan Pathfinder R51 </Td> </Tr> <Tr> <Th_colspan="2"> Powertrain </Th> </Tr> <Tr> <Th> Engine </Th> <Td> 5.6 L V8 VK56DE </Td> </Tr> <Tr> <Th> Transmission </Th> <Td> 5 - speed automatic </Td> </Tr> <Tr> <Th_colspan="2"> Dimensions </Th> </Tr> <Tr> <Th> Wheelbase </Th> <Td> 3,129 mm (123.2 in) </Td> </Tr> <Tr> <Th> Length </Th> <Td> 5,255 mm (206.9 in) </Td> </Tr> <Tr> <Th> Width </Th> <Td> 2008--2010: 2,019 mm (79.5 in) 2004--2007: 2,002 mm (78.8 in) </Td> </Tr> <Tr> <Th> Height </Th> <Td> 2005--2010 2WD: 1,956 mm (77.0 in) 2004 & 2008--2010 4WD: 1,999 mm (78.7 in) 2005--2007 4WD: 1,976 mm (77.8 in) </Td> </Tr> <Tr> <Th> Curb weight </Th> <Td> 2,539 kg (5,597 lb) </Td> </Tr> </Table>
