First things first... This has 99.99% nothing in common with the road car that's been on and off again development. The same goes for the GTR and the rest. Some of the body parts resemble the street car. because of this Honda will not be using this platform for Development or research for the road car. They have a finished product but can't release it yet due to many things one of which is market concerns and economy. But it will come to market when they see fit. The reason for the change in gt500 is because they could not race the nsx anymore and needed a replacement. Also lotus will be using the LFA engine in one of there future cars maybe the new esprit from what I'm told from an insider in Toyota/lexus. There is a sound clip and now video but I'm on my Mobile so I can't post it yet.
