施政報告: 買36台電動巴士...

In my opinion, it is not viable to pursue a 100% electric solution.
For years, we have been using little to none electronics in buses.
We are just at the beginning of the hybrid bus trial.
We still have no idea whether having half the powertrain as electronic components will work in Hong Kong or not.
And now they want to introduce fully electric vehicles. I cannot see why they have to rush.
The diesel buses are way more environmentally friendly than older diesel buses already.
They can send newer buses to areas known to be easily trapping pollutants as a temporary solution as they wait for newer designs to come out.
I do not see an urgent need for electric solutions.

So what you are now saying is completely different from what the initial post I was replying, which you were referring that the parallel drive system has superceded the serial drive system. This is clearly not the case. In fact, in a parallel drive system, the engine is actually used to drive the vehicle directly. Have a ride on the B5, and you'll see how it works.

well, this is at some point, as I referred to, when the batteries are low, and when accelerating. It is usually off when travel at steady speed and deceleration. Hence the engine is used to charge the battery as well as drive the vehicle directly sometime, but not all the time. Have a try on the Toyota Prius and you should know what I am talking about.

So far, the parallel drive system has proved to be the one that better suit HK environment, and there is no doubt about that.
