I have seen something where BYD have used their tech to manufacture buses.these seem to be working well.

BYD seem to be a very large company that has the funding to develop new ideas mainly in Battery powered machinery.

Simple but effective in entering the market and over time might take on the major companies.

Companies like some leading European manufacturers simply improve their products over what the market demands and there for will ultamitly lose market share for being to expensive to purchase and maintain.

This is being shown by the emergence of some Asian mamufactures.
