Looks to me they are copying what i did with the S4 and the S44 about 4-5 years ago by moving the motor further forwards
they worked great and i am sure with Tamiya quality this will also be a great car.
Will be nice to have a choice of belt or shaft 4wd tamiya's
Also looks like you can swap the diff's around inside the casings, so it would be possible to move the motor position around. And i think you could get a stick pack of lipos in there as well.
