Jun 02, 2008 Whats the future of gasoline engines?

With the way gas prices are on the rise, what will be the future for automobiles, or more specifically, gasoline engines? We all know that new technologies have already been progressing the last few years such as electric-based hybrids and flex fuel among others. While these new technologies will take hold and start to gain footing, I personally don't see the gasoline based engine disappear anytime soon.
