Just read this article on the 4car website:

This is the bit that made me laugh: "Renault is also to use more laser-welding, and plans to cut its manufacturing costs at many plants by rebuilding older equipment rather than buying new tooling. It is to reduce the number of quality inspection points in its factories, as more precise welding techniques and the stalling of imperfect vehicles before they go onto the final assembly lines, has meant that the usual 500 inspection points can be reduced to just 80."
Fair enough, but it remains to be seen if the next generation Clio removes all the current quality issues?
