What Do We Know About The Elio Chassis?

You're good at synthesizing, and accessing what you know you've seen.

So just what are the pros and cons of body-and-frame vs unibody construction?

IMHO, both have their place. Body-and-frame 'good' if you're using composites (i.e. - Corvette, Elio, etc...) to keep the vehicle light. Unibody either requires a steel (standard) or aluminum (not cheap) monocoque body to retain rigidity, or Carbon Fiber and a b*ttload of money to keep the weight down. I prefer the body-and-frame for an Elio type vehicle. If you do get something "dinged", it'll have no affect on the structural integrity.

I think the main reason for the glue on panels would be weight savings ,the tubular construction for safety ,and rigidity plus built in roll over protection.
So this image captured from the new EM investor inquiries video not only gives nice supplier information but also reveals a lot of changes to the EM chassis design. The over chassis and vehicle design now appears to be nicely fleshed out and about ready for pre-production testing.
Some chassis changes which have already been pointed out by myself and others:
The 'crush zone' details in the front are now present (see dimples in frame side).
The 'A' pillar base is now formed rather than the welded block of the P4. The forward main structural element runs to the back of the 'A' pillar base for integrity in that spar.
The 'B' pillar is now a formed and laminated section for strength, different from the P4 prototype stick construction, and typical of 'best practices' car construction..
The rear seat is integrated into the storage shelf/wheel well structure.
As expected the roof line behind the driver is less steep and more rounded which adds the extra bit of headroom which should allow an average height adult male to sit in the back seat comfortably. This also allows for about 50% larger rear windows which should make the space feel larger and less confined than in the P4.
Also note the low position of the engine, a positive feature for flat cornering and reducing the requirement for anti-sway bar to be as stiff thus improving ride and tracking.
As expected the exhaust system has been rerouted down the right side of the vehicle however what is unexpected is the exhaust exiting at the rear to the left of the rear wheel. As until now we have been told that the exhaust would not exit at the rear because the fuel tank was in the way, making routing the exhaust to the rear difficult, this image now has me wondering if the recent news about the slight fuel tank size reduction may actually be attributable to this new exhaust routing.
This view of the chassis shows a lot of changes from the P4 construction and some earlier images. It shows stamped/formed pieces, door opening flanges for seals, crush zone details, and the front seat slider mechanism, probably with a 'last position' feature for movement during rear seat entrance/exit.

Hey, G1, this is great, but it's a damn fuzzogram. Can you get an .eps version or a high res jpg file we can download?

If memory serves, it actually is 1/2 inch wider that the front tires. But in this drawing it looks larger in diameter, too. I don't know if it really is or not. Ask the Elio Oracle.
