Guys, as much as I'd like to see the 2wd it's all a matter of money I'm afraid, let me try and explain......
The 8th was apparently significantly far on in its development.
There is a lot of money in 8th.
So.... get the 8th car finished.
The truggy, whatever way you look at it, will be similar to the 8th buggy and share many parts too I'd expect, so..... finish buggy - then design a few parts to make a truggy.
Bingo, two cars in a big market in a short~ish time. It's how all engineering works.
Hopefully it will give them more money to develop the 2wd though
