If Tamiya wanted to get into the mini 4wd cars they should have used the 30th anniversary Porsche TA05 chassis and shrink it 20mm more. Standard size 540 motor (like everyone else) and standard battery size (like everyone else)

2wd and 4wd are 2 different animals. The fun of a 2wd is the challenge to be able drive it well, especially if it a rwd. Mini 4wd pretty much is a shrunken TC. If you want a 4wd mini, I'd just get an ABC Genetics.
