Team members each learn three jobs and rotate, partly to ensure there are no gaps caused by absence and partly because, "at the end of the day it's a production line and it's going to be boring. And some jobs are more difficult or less comfortable in ergonomic terms, another reason to rotate."
Among all that these guys keep track of multiple components - Sunderland builds for 53 different countries, and even the language labels must be right. I'm told the device that makes quality fool-proof is called a poky yoke - "If the torque on the suspension bolts isn't done properly it'll auto stop the line; we have a lot of pokey-yokey devices around the shop."
Quality feedback stations punctuate the factory floor, an enormous dark cavern clanking with machinery, only the area immediately around the line brightly lit, to save power.
An axle, engine and transmission are lifted into a Juke and bolted down within a minute, "This is one of the most skilled areas, to put all that in at this speed, and the two operators have to work very closely together."
Each Juke takes three hours to complete before its final inspection, including an eight-minute rainstorm, a 1.7km drive over various surfaces plus rolling road tests, and I'm here to tell you that rocketing along at 110kph while pedestrians overtake you is a very strange feeling indeed.
Sunderland built 423,000 Nissans last year, one in three cars made in the UK from all brands. It exports 80 per cent of them, including the Jukes we'll drive in January.
