自从2016年发表h-tron氢动力概念车后，Audi就聚焦在开发e-tron电动车，
并放慢研发氢动力车的脚步。
但现在Audi担心随着电动车销售成长，未来电池原物料将发生短缺 (价格成本上涨)，
因此Audi又重新转向发展氢动力车了。
Audi CEO Bram Schot说他们要优先研发氢动力车了，投入更多钱、更多人力和信心。

“We really want to speed it up,” Schot said. “We are going to put more priority into hydrogen fuel cells – more money, more capacity of people and more confidence.”
Schot, who succeeded Rupert Stadler as Audi chairman in January, pointed to the scarcity of materials and subsequent doubts over the high-volume supply of batteries as just two concerns facing car makers.
“If this modality is here to stay, then you have to try to find the most effective and efficient way to drive electric,” he said. “And then you come to hydrogen fuel cells.”
Bram Schot说Audi第六代氢动力的原型车将在今年内发表，
在2021年，就会有少量试产的Audi氢动力车提供给消费者租赁。
Audi氢动力车的量产时程可能会落在2020年代下半，也就是2025年后。
Audi认为氢动力车有几个优点
1. 节省电池的使用量，电池容量可以缩小52%~63%。
以今年即将发表的Audi六代氢动力原型车为例，只需要35~40kWh的电池，
比Audi e-tron 95kWh少了52%~63%。
2. 氢动力车的行驶里程较远，2016 h-tron加满可以行驶600公里远
3. 可以少建很多充电站
4. 在冬天低温时，不用担心电池蓄电力怕冷的问题。

它占去整个燃料电池系统成本的2/3，未来需要研发出更便宜的制程才行。

The plans to intensify hydrogen development at Audi also centre on attempts to create greater range and lessen the requirement for charging during long journeys and in cold weather.
Depending on the model, the battery capacity is put at 35-40kWh, significantly less than Audi’s all-electric E-tron, at 95kWh. It is sufficient for up to 93 miles of range alone.
==心得==
2016年h-tron的氢动力车已能行驶里程600公里，四分钟就能加满储氢桶，
所需的电池容量也小很多，未来是消费者的另一种环保选择。
目前有Toyota、Honda、奔驰、Audi、Hyundai在研发氢动力乘用车，
另外还有业者在研发氢动力大卡车，号称15分钟可以加满卡车的大型储氢桶。
