Hi Ron,
Thank you very much for the link.
For interested readers, Renault have this 27 page press kit on their 2014 F1 power
unit which they designate as "Energy F1-2014".

Development of it began in June of 2011 but the first race-intent unit only ran
on a dyno in June 2013 and is scheduled to be fitted to a car in early January 2014.
I can't imagine these people will be taking much time off over Christmas.
The development costs must be extraordinary. However, to try and keep this
under control, the FIA is planning a staged freeze on engine development through
to 2019. For example, by 2015, 8% of the power train components by weight
will be frozen and by 2019, 95%.
