Has anyone looked into an NGV conversion for an RS4, or any other Audi for that matter? I think this would be a great way to make this car fuel efficient. That would just be too cool to have a 420 hp low emissions vehicle. Is it even possible with such a high compression engine? The Honda Civic NGV is only 110 hp. :(
