yea, but if its an X6 why would it still have the camouflage on the front bumper ???

looks more like an X5, look at the Headlamps
as for the camo tape. Could be the LCI X5(I could be wrong tho d: )

Also, how the hell they can prevent the engine from over heating with all that surrounding closure?

That's the whole idea. Take heat that you would be just throwing to the ambient air (through the radiator, exhaust, and general engine heat losses), capture it and transfer it to make electricity.

In chemical processes (like the combined cycle power plants), waste heat is often converted to steam and/or used to heat other processes going on (through heat exchangers). In a combine cycle power plant, you take heat generate from burning natural gas (usually) in a combustion turbine (think jet engine), convert it to high pressure steam and run a steam turbine. So you have essentially used the waste heat from the first combustion process to generate more electricity from the steam turbine. In chemical plants and refining operations, integration of processes to make use of heat generated from one process to provide energy to another is absolutely key to being able the make almost anything economically.

In the car, it is probably not economical to put in a steam turbine because of cost, and more likely because the steam you could generate with the temperatures engines run at is not high energy to make "high quality" steam.

The main challenge is probably how to cheaply transfer the engine heat away and use it without waste.

With the available heat at low temperatures, it is difficult to use it because the inherent maximum efficiency with be [T(hot) - T(cold)]/T(hot) (where T must be in absolute temperature units like Kelvin or Rankine), which probably won't be over 50% with the possible exception of the exhaust gases. T(hot) would be the engine or exhaust temperature and T(cold) would be the ambient temperature.

yes, that might be true since the latest spy shots suggest that the next generation X5 will share the headlights with the X6.

Actually I've done engine cooking on a motorcycle before... wrap potatoes in foil and lodge them next to the engine. Ride for an hour, and voila! baked potato. Guys riding behind you tend to get hungry though...

Indeed, though weight and space doesn't help either (yet). That was clear in the BMW TurboSteamer prototype http://www.autoblog.com/2005/12/09/b...-hot-and-goes/

Once it is further developed (in some 10 years), it should be a great addition to further enhance efficiency

Cool... more moving parts is always a worry from a maintenance point of view, especially when it is intimately mated with the drive train.

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)



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.



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!

im sorry but i still think its retarded.. and here is why..

since a simple USB connection costs about 400 bux on a BMW, a system like that is not gonna be cheaper then 3000 dollars..

now lets say u consume about 100 worth of gas a week.. .02 % of startups would probebly be around .50 if not cheaper since the percentage saved is ONLY of FUCKING cold starts.. now if ur the retard one that wants to pay 3000 for a system that would save u .50 a week then go ahead.. u see how shity i looked now cuz i caled u retarded. its just my opinion and u can blow me if u dont like it)

on electric cars.. instead of doing carbon fiber roof and all that gay stuff they can do solar panel roof and hood that will help with being able to do longer trips.. now i know they are underdeveloped but as much as i LOVE bmw (current owner of 3cars- 1983 518i 2006 330i and 2008 135i) they JUST started thinkin about hybryds and all that bullshit dynamic fancy names they come up with inorder to get better mpgs while toyota and honda been doing it for YEARS..
if u got beef with my im a vegitarian` :P no hard feelings
sorry
if u r ever in town ill buy u a beer..

heat will destroy whatever they wrap the engine with in the medium term. Did they move Bangle to engineering ? sounds like a lot a whacky ideas from summer interns ?
