i remember this "concept" engine design from a few years ago. is it still be developed or did it get shelved? The design would be great for GM. its a totally new engine design, and it would show that GM is leading in development of technology. also, its size and weight would allow it fit in many different cars. imagine a small 4.0xv8 that is the same length as a 4banger, the same width as a v-6 but the power or a nice v-8. any new updates or info. thanks!!!!!!!!
