I just got a brand new Scion tc, Iv had it for about a week and Iv noticed that after driving around for like 15min it gets REALLY hot under the hood and i could litteraly burn myself if i touch the area just over the passenger side head light. Is this normal or should i check it out????

I know my Honda got really hot nothing to worry about. If it really bothers you I think they make a heat sheild you can put under the hood.

The number one hp robbing unit in your car is your radiator. It robbs you of power and mileage. As I was explained in auto shop in early college an efficent and very powerfull engine would not give up any heat. It would retain all energy for the best result. So what I'm trying to say is as engines get better they will get hotter. Look at a engine from say the 70's. You would blow the radiator by the time most modern engines are warmed up.

No, the #1 power thief is a non-adiabatic thermal cycle. The exhaust is also hot. You lose about 1/3 of the energy to the cooling system, 1/3 to the exhaust and get about 1/3 in kinetic energy. An adiabatic engine would be cold to the touch, have ambient temperature exhaust, and no cooling system would be needed. It would also be 100% thermally efficient. It is the holy grail of engine design, and the closest man has come is some diesels that are just a bit over 50% thermally efficient. So, as engines get better, they get colder.

So your saying the engine would retain all heat to make more energy?
The ideal engine converts all the heat available from the fuel to kinetic energy. It doesn't retain any heat at all, it turns it all into motion.
