Teensy 3.6 Maximum CAN Bitrate

Apologies in advance since I think this has been covered, but what is the maximum bitrate for two Teensy 3.6 assuming that I get compatible transceivers? Searching for "CAN" was giving me erroneous results and I'm trying to decide whether to have my whole CAN network be Teensy 3.6s or a mix of microcontrollers, knowing that a mix would mean some would only support CAN 1.0.

Thanks!
Brian
 
theres a dual can board on tindie designed to piggyback the Teensy 3.6, CAN spec on all supported teensies are CAN2.0B
 
only Teensy 4.0/4.1 supports CANFD on CAN3 only. it is also backwards compatible with 2.0B in FD mode, or run legacy 2.0B mode only on CAN3.

Max bitrate there by the controller in FD mode is 8Mbps, supported by both skpang and pjrc breakout board transceivers (and proper setClock() frequency of the library)

all arbitrations are 1MBps max, even in FD mode.
only the data can be transfered at up to 8mbps in FD mode.
FD mode supports up to 64bytes data vs 8 for CAN2.0B
