In 2009, BMW will release the hybrid version of its new 7 Series that made its debut a few days ago. According to the folks at CarMagazine UK, the BMW 7 Series hybrid will be powered by a 4.4L V8 gasoline-electric engine that runs on Lithium-Ion batteries.
Same sources state that the fuel-economy would not be as great as we expect it to be and it will definitely be less than the 32.6 MPG, achieved by the 730d. On top of this, the base price is expected to be higher than the top 750i model.
Even though the fuel-economy ratio is not that great, BMW sees a demand in the hybrid market. Dr. Klaus Draeger, BMW board member responsible for R&D and project leader for the new 7-Series said: ”Some customers really want a V8 with very good fuel economy.”
Now, Mr. Draeger, please define "V8 with very good fuel economy".[Source: eGMcartech ]
