"analog speedometer" does not need much fewer chips than a fancy display, it all goes over canbus 
and mechanical gauges are abandoned three decades ago
but it is easy today, you can shove any dashboard into a modern car with just a minor firmware tweak, they might have some stocks from other model

That may also be about avoiding an LCD (and driver). A customer of mine has been quoted >1 year leadtime for some special LCD monitors

They dont meant "mechanical gauges" but an electronic one like a 90ies solution a tiny 8/16bitter with air coil drivers and CAN or they could even go NOS
CS8190 etc both as a replacement of the big LCD and dedicated 32bit MCU +memory and all. It's cheaper, no software tweak and the car can be shipped
and sold instead of sitting on the shelf half built waiting for unobtanium like Ford done did with some of their models. But it would be interesting to see what
Peugeot actually did put in the 308.



Reely old school still electric!


Ultra 80ies old school retro mood with VFD old school, or something!

Maybe today, but certainly not historically. Intel microprocessors were the only game in town for many years since IBM adopted the 8086/8088, until AMD and a few others got into the business. Intel made a fortune out of the IBMPC and IBM clones.

Yes, I did mean lately. Intel mostly got out of the MCU market in the mid 90s if I remember right, although I think they kept manufacturing legacy products for many years.
