The specifications for BMW X5 45e are back on their US website. If you check
BMW UK though, it says total torque is 600 N-m (442.5 lb-ft), Engine torque is 450 N-m (332 lb-ft) and Electric Engine torque is 265 N-m (195 lb-ft). If you add 450+265 = 715 N-m, so clearly that's wrong. The electric engine torque is 150 N-m (110 lb-ft). BMW US shows 77 lb-ft.
I initially thought maybe the electric torque is less in the US because the battery is limited to a lower capacity but, total torque should also be lower so I'm pretty sure they just messed up.
