Note there's camuflage in the front bumper. Could it be the F10 5 series? Hummm
in that case they gave some new info (about the front lights), as they aren't covered unlike the testing prototypes. And they don't look to be the 5GT...perhaps.
Other than that, the idea of recovering heat energy in one way or another isn't new, what is new is that finally someone took the plunge to work seriously on it and can make it economically viable. Thumbs up for BMW, and really hope it's already on the 5 series, along with other new measures for the Efficient Dynamics (ie. the new aero lay out around the wheels?)

Problems were that it was too fragile, too expensive and very difficult to manufacture...in fact it was almost impossible to build two identical ones (to current standard)

ITS RETARDED...
why dont they just do an electric car and forget about all this bullshit..its been done before by GM 8 years ago...all this crap is just gonna drive the price of the cars even higher and wont justify the .2% fuel savings.

Now thats the retarded comment. DO you think they spend the money elsewhere for fun?
Don't be overly and stupedly simplistic like some ignorant pseudo-ecologists.
While electric engines beat internal combustion ones in efficiency, simplicity, torque and other aspects, the problem with electric cars is that batteries are so undeveloped and "useless", with a really small energy density. Petrol is very dominant in that respect.
How many km do you think can be done with a electric car, and with a fuel tank?
Electric cars at best struggle to do more than 400km, while some efficient diesels have gone over 1500km. And most electric cars on sale don't even surpass 150km! Would you, or customers be up to that?
Whats more, would you be up to waiting for few hours (no less than 3, for example), while petrol refuelling takes you 3...minutes!?
Please get informed before saying BS.
The major challenge with E-cars is storage, which for now is rubbish and still needs lot of investment in new developments.
Whats more electric engines get the energy from somewhere, a pollutant source in the majority of cases too. In fact many times coming from coal, that is more pollutant than petrol!
Currently electric cars rather than solving the pollution/energy problem, simply change the place of contaminant emissions.
Lets not forget that while big energy powerplants can beat the 30%aprox efficiency of IC engines, the electrification and all the energy transport, which is then converted into chemical energy in the batteries and back into electricity doesn't overall get much better than IC. Actually only nuclear plants and gas combined cycles could be "winners" in this respect.
Needless to say that batteries add major weight to the car, overall increasing energy consumption.

Can I put a bbq grill on my engine and cook dinner on the drive home? 2000 rpm for medium rare?

You don't need that. Actually it is widely "tradition" in summer in Sevilla (southern Spain) to fry eggs and other stuff over the car hood. The good thing is that they don' need to start the engine, cause that heat is coming...from the "horrible" sunshine there!
