Not a structural component like the chassis.
So when your wife goes and rear ends somebody, the pre-preg chassis needs to be completely replaced and therefore has to have the whole car disassembled and reassembled on a new chassis?
Insurance rates would skyrocket and the car would get a bum reputation right from the outset.
On top of all that there would have to be a SERIOUS retool in order to have pre-preg autoclaved manufacture on a scale to bring the returns required to make it happen.
GM's bread and butter for the past 10 years has been the truck market.
How exactly does a CF investment make returns there?
Then there's the steel union. Can you imagine dropping the demand for steel from GM by probably 50%.
No way in hell.
But back on topic. I'm pretty sure the block in the Impala is the same as the truck motor. When I saw it at the LA auto show, from what I could tell, it looked nearly the same.

CF is great and it will become more comon (in high end cars) as time goes on. the problem is the manufatureing prosses is so much more labour intersive and requires larger amounts or resourses. its great stuff for low volume pruction but for mass it would coz har to much. Aluminium (so im english) is a better material to use for a car chassis and can be easier than steel if you bond the components instead of weld them! also much lighter.
thanks Chris.
thanks Chris.
I could see the accessory drive (with modified aftermarket cranks possibly), making its way into rods with tight fit specs... and perhaps maybe someone will toy with trying make more room in the already tight C5/C6 engine compartments for power adders... a big single hairdryer at or near the stock location of the original waterpump would be cool to see. Whatever comes of the LS4 means folks will have more options to amke things work for their projects I would think

There's a fair amount of LS4 info in this thread:
http://www.fiero.nl/forum/Forum2/HTML/058437.html
I think if I were gonna swap a V8 in to my Fiero, I'd do the LS4 & transaxle setup.
I also think that the most significant advancement is the Displacement on Demand feature. V4 to V8 automagically. The technology there is pretty cool. I think that's more interesting than the FWD configuration.

I bet when HP Tuners comes out for DOD vehicles, that's the first thing they'll disable is DOD.
DOD might not be that bad if they do it right. If it kicks in when Cruise is enabled than whats the problem? This technology has been around in Caddys in the 80's the V-8-6-4 if I am not mistaken. Besides whats wrong with getting a few more mpg with the way the petroleum prices are?
