The ceramic engines are quite the technological step, but they are veryyyyyy brittle--they are only good for one race...so you can only really start them once and race it once before they blow up or break apart...The coolant logic is what I've always heard, also. Honda's been experimenting with ceramic engines and running them glowing red hot. They've had a lot of success and get tremendous fuel mileage out of them.
