SAM V71 devices are members of a family of Automotive Flash microcontrollers based on the high-performance 32-bit ARM Cortex-M7 processor with Floating Point Unit (FPU). These devices operate at up to 300MHz and feature up to 2048 Kbytes of Flash, up to 384 Kbytes
Automotive Grade — AEC-Q100 Grade 2 (-40C / 105C) qualified
ChibiOS actually supports AT91SAM7x?! Is that includes this chip, then we've got ourselves an automotive grade chip with ChibiOS and probably free GCC compiler. http://www.chibios.org/dokuwiki/doku.php?id=chibios:architectures

Not all the peripheral is supported by the HAL http://www.chibios.org/dokuwiki/doku.php?id=chibios:matrix but still, this is pretty interesting.

No unfortunately the AT91SAM7x is a really old ARM7TDMI based Atmel MCU.
These SAM V71 are very new and based on ARM Cortex M7 core.
Now I did a quick comparison and I am not sure there is much of an advantage over -for example- the STM32F7, apart from the automotive temperature rating of course.
So no advanced timer and no 5V Analog connectivity for instance..
