I recently did technical deep dives on my late model Volvo XC90 and XC60. I was amazed to still see SuperH SH4 processors in use in various parts of the telematics system.
I worked in automative for lots of years. Up until around 2010 SH4 was mostly the dominating architecture for infotainment systems. Either with Windows CE or QNX running on top of it. Due to long development and product cycles as well as software reuse new cars with SH processors might have been released up to much later points in time.
