At those numbers the limitation is not the engine tech but the strength of the drivetrain. Most any electric motor can snap an axle if not regulated properly.

Most of the largest mining trucks are already electric drive, have been for many years, with an IC generator powering an electric motor. That is easier at scale than building a massive transmission.
