Interesting, must be something new this year. I know that last summer they shut down for much, if not most of August.
This was posted by the production manager at Lotus last summer on another platform:
"So here we are
Its summer shutdown
I would just like to thank every single one of my production team for their efforts so far this year in what are exciting times for
#lotus
The year has had its challenges as always but as always the whole team steps forward and works hard to deliver
The
#emira launch team have done such a fantastic job launching our new and most exciting product taking us towards our Vision 80 target
Enjoy your holiday team and have a well earnt rest
And for everyone one else at
#lotus who are taking a break thank you for your support and enjoy
Out of office on time to relax"
On Lotustalk there are threads from back in 2004, just before the federal Elises came ashore, lamenting that production will be slowed as the plant had its annual August shut down.
