New turbocharger technology with electric motor (ERS)
I have owned several turbocharged vehicles and am glad to see more manufacturers are starting to use them in their designs.
I have been reading about the ERS system ( http://www.formula1.com/inside_f1/understanding_the_sport/8763.html ) which places an electric motor-generator between the turbine and the compressor.
This appears to have GREAT potential. The energy in the exhaust which used to be lost out the tailpipe can now be harnessed by converting it to electricity to drive the rear wheels. Additionally, this motor can be powered by the battery to 'pre spin' the blower so there is no 'turbo lag'
I can say that technology which is being used in Formula1 often trickles down to what we drive on the streets. Many of the engineers which have looked at this technology suggest it is a "game changer" for any internal-combustion engine.
I am hoping to get some discussion going here about this ERS technology.

Here is another link that explains it http://www.electric-vehiclenews.com/2013/07/2014-formula-one-exhaust-energy.html
In the Formula1 application , this can add up to 160bhp to the drive wheels (electrically)
Let me be clear, this technology dates back to WW2.... but has only recently become feasible due to advances in turbocharging and electric-motors.
The F1 folks claim this system will conserve about 30% of the fuel they used to consume in a race. If this translates to daily-drivers.... consider the possibility of getting 30% better fuel-economy over what you are getting in today's vehicles. (Without any sacrifice in power!)
Yet another reason to put your money on the ICE in the 21st century horse race for fuel economy.
