I'm hoping that the turbocharging system makes it into production vehicles. Being able to utilize the energy wasted by the exhaust system is a big boost (pun very intended) in efficiency. If the turbine is able to always spin at a given RPM, then it can generate enough electricity to forgo the alternator, maybe the mechanical water pump and A/C compressor (replaced by electric ones), and power an electric power steering motor. This would also help in packaging.
