That 007, like its namesake, sounds a little bit to good to be true unless Dongfeng have just developed a solid state battery suitable for mass production. IMO 11.9 kWh per 100km of real world range for a long range, high performance mid size sedan substantially stretches the credibility envelope. Currently the most efficient mid size production EV is the Telsa M3 RWD at 15.1 kWh per 100km. The Hyundai Kona Std with similar specs comes in next at 15.7 kWh per 100km. In both cases the quicker, bigger battery siblings with AWD and longer range are less efficient so its more likely the 007 with its obviously less aerodynamic front end will come in at around 18 kWh per 100km about a 50% increase on Dongfeng's figure.
Reading a little further it seems that the 007 will have several different specs so the HiPo and Range extender versions won't be the models with the claimed 11.9 kWh efficiency. In fact the Range extender version will probably have the worst overall efficiency if it just has an ICE generator to enable its advertised 1200km range. I await further updates on the 007 to see if Dongfeng's claims match reality.

I’ve seen these battery packs in the past, so I dropped this one as a possibility with the idea of avoiding using a fossil fuel combination to charge the EV battery.
How credible they may be, may be seen as uncertain
