Never known for making environmental friendly vehicles, BMW now believes that they have a future in hydrogen. Until recently, BMW has been very quiet about hybrid electric vehicles. That is changing... BMW is working on a hybrid using an ultra-capacitor that is nothing like we are used to.
"Ours is lighter, faster and more efficient," says BWM Technology Guru Professor Freymann. Super capacitors, power boosted by regenerative braking, replace batteries. "[The super capacitors] are lighter and store less power, but unlike batteries we can use all their power — all 100 percent." So they give a quick, high-power, short-term "fix" to a small electric motor (mated to a conventional gasoline engine), used only for standing-start acceleration. "An electric engine has a lot of torque at low revs — that is its main benefit — so it's ideal for fast initial acceleration. At higher revs, once you've begun to accelerate, nothing can beat an internal combustion engine. Our hybrid approach combines the best characteristics of both engines."
It will be interesting to see what BMW does for the hybrid electric vehicle and the ultracapacitor.... stay tuned...
