It sure is sexy, but it's unfortunate that they had to mount the turbos so low that they require a return pump to get oil back to the reservoir. This is why I no longer have the STS twin turbo mounted on my car. The oil return is the weak link in the system. It doesn't matter if you are pumping it 8 feet or 8 inches, if it fails, you are done. Gravity is an infallible pump. Move those turbos up a few inches and let gravity do it's thing.

“Superchargers are easier to package and the induction system is simpler. The downside is that it takes horsepower to turn them. A turbo does not take that horsepower to turn but is much more complex for packaging. For example the Twin Turbo Concept has both oil and coolant fed to the turbos, combine that with the location of the turbos and you need an oil return pump. With Ford’s experience in turbocharging in production we saw this as an opportunity to experiment with the Cobra Jet.”
