But they are rubbish - hybrids that is in general. BMW have been forced to go with the flow.
Take a look at the this car's Gallery pictures man. What's the point of a 4WD, SAV/AAV as BMW calls theirs if it sits on the ground? Good for reduced drag, but then why bother with automobiles at all beyond functional objects? It looks like one of those c.100gCO2/km VW BlueMotion Polos. Like an up-turned jelly mould. Do the wheels double up as childrens' windmills or perhaps wind turbines at speed?
Who's going to pay for all the extra kit with hybrids - all for the sake of theoretical, never achieveable in practice, sub 200gCO2 emissions? 8 speed heavy, complicated autos, extra motor, battery pack, controls, solar roof panels in cloudy Northern Europe, separate high-voltage system, instructions for dealership workshops etc., disposal/replacement of battery packs, 2nd/3rd hand reliability and operability factors - all a potential nightmare, oh but so good for the cool 'Hybrid' bullshit Toyota image.
BMW were, until Toyota and Hybrid mania came along, working away on Wasserstoff, Hydrogen fuel for engines and latterly fuel cells, again powered by hydrogen. This was and will again be the way to go. In the meantime, pure internal combustion technology, not petrol/diesel-electric hybrids like that showcased by Mercedes-Benz at Frankfurt last year, the Otto-Diesel engine is the way to go - diesel torque and efficiency without diesel soot, NOx or expense adding particulate traps and/or urea-catalysors. VW Group have also been doing excellent work with the low c.c. direct injection charged engines - very clean and highly efficient without all the weight, cost and fuss of the dreaded hybrids.
Do you really want to drag aroung several hundred more kilos of already bloated vehicle just to be able to say I can theoretically do 10mpg more in ideal test conditions and pay through the nose for the priviledge and drive something that looks lile a parody to boot? Madness.
If you have an uncontrollable urge to save the planet and boast of driving start-of-the-art 'green' machinery you should be wishing for all-electric vehicles or fuel cell powered vehicles. The cost, weight, size(energy density) and overall efficiency of battery packs will only come down to somewhere near reasonable cost with true mass production and the stepped up recycling facilities to go with it. The electricity for the 'plug in' car and hydrogen production will have to come from nuclear power stations or else in your carbon-obsessed world you're back to square one. You will not generate one tenth of the requisite elecrtricity from ranks of non-turning supposed 1MW-rated wind turbines or from solar power at Northern latitudes beyond 50deg..
