I've started on a chassis that will eventually be used to build a supercar with, as per the unofficial Technic rite-of-passage:
Notable features include a floating differential setup that's borrowed from Thirdwigg's 8081 RT MOC (found here: http://thirdwigg.com/2014/01/12/8081-rt/)
The always necessary underside shot:
The right and left sides, respectively:
The back end:
And a shot from the top:
A lot of this is placeholder; the entire front steered suspension setup is also borrowed from Thirdwigg's MOC and as such is held on with the power of Grayskull wishful thinking. In addition, the chassis is about as short as it will get due to the fact that the drivetrain is artificially long to avoid issues with the half-width offset generated by the floating differential, and the servo motor is set directly end-to-end with the L-motor. Finally, I think the chassis overall is a little too tall for a supercar, and I would like to lower that somewhat.
Basically, I'm looking for what I can improve to make this a bit more compact (and yet still have room for a battery, something essential I forgot to put into this) and what I can do to make it stronger. This project is derived from the thread I made recently about developing a compact suspension (http://www.eurobricks.com/forum/index.php?showtopic=97809) - as you can see, I ended up using Thirdwigg's solution as it was going to be much better than anything I could come up with in a reasonable amount of time. Let's finish off this post with some nice pictures of the rear drivetrain, with and without the various supporting elements!
