The thing about these "new" engines, is that, if you understand internal combustion engine design and thermodynamic fundamentals whatsoever, the power and torque figures are really not that impressive at all. It's really to be expected if you look at the physics of it. These concepts have been around for years. What is impressive, if the fact that they are doing it in PRODUCTION cars and at the PRICE they are doing it at. It says a lot for modern manufacturing and engineering. The performance specs of these engines are nothing magical, but the reliability and the low cost is.
