The STM32F401VCT6: The 100-LQFP package brings out 81 I/O.
No automotive-grade qualification is listed, so for under-hood or chassis-domain use you would look at the STM32F4 automotive line.
It uses an ARM Cortex-M4 core, 32-bit single-core, with single-cycle DSP and FPU, running at 84 MHz.
A lower-power alternative is the STM32L151CBU6A, which uses a Cortex-M3 core at 32 MHz with similar peripheral set but less RAM and I/O. The STM32F401VCT6 offers higher performance and more memory for DSP or control applications.
