Formula E plotting Gen4 rules with hydrogen shift touted
By:Matt Kew
Formula E will imminently begin plotting its Gen4 regulations, which could lead the championship to shift to adopting hydrogen fuel cell technology to attract new manufacturers to the grid.

During the pre-season test in Valencia last month,Formula E released the first teaser images of its delta wing-inspired Gen3 designthat will have 470bhp and a total regenerative braking capacity of 600kW.
The new rules will begin in the 2022-23 season and while private testing from car constructor Spark Racing Technology is in progress, the teams will take delivery of the new machinery in the spring.
This will be followed by a facelift of the car and technology for a Gen3 Evo rule set.
But the Gen4 regulations are already under consideration, and new manufacturers will be invited to “brainstorm” their concepts for the future direction of Formula E.
Speaking toMotorsport.tv, championship co-founder Alejandro Agag revealed: “Gen3 is already amazing.
“But we’re just going to start now thinking on Gen4, which is coming in five years.We have to start the discussion now.
“We will, of course, invite the OEMs and the manufacturers that are with us now.
“But we will also expand the group to invite all the manufacturers to brainstorm with a very open mind about how Gen4 should look.
“There, everything is open. Anything could happen.”
As part of this open approach, Formula E will consider adopting hydrogen fuel cell technology to power the electric motors.
Agag continued: “Hydrogen is within the licence of Formula E with the FIA [a supposed exclusive 25-year rights deal to electric-only single-seater racing].
“There are two ways to use hydrogen, one way is to burn the hydrogen, which is very inefficient, but some people are working on maybe making it more efficient.

“The other way, which is the one we would use, is a hydrogen fuel cell that basically produces electricity that then powers an electric motor.
“So as soon as those technologies start being widely available and operating in a racing level, we will definitely look into those.”
A hydrogen fuel cell is already used by effective sister series Extreme E to charge the nine Odyssey 21 E-SUVs on site at each race event.
In 2020, Mercedes technical partner HWA was a founding party in the announcement of the HYRAZE League concept - a hydrogen-powered sportscar series projected to launch with 800bhp cars in 2023.
But Agag did warn about the spiralling costs that come with greater technical freedom, although Formula E will impose a €25 million manufacturer cost cap over two consecutive seasons coming into effect on 1 October 2022.
Agag said: “You need to give that amount of freedom so manufacturers can develop technologies and have a reason why to compete in the championship.
“The balance is the key.
“[But] the more freedom you give, the more money the teams have to spend and then after a little bit they run out of money, and they leave the championship.”

机翻见谅
电动方程式即将开始制定其Gen4法规，这可能导致锦标赛转向采用氢燃料电池技术，以吸引新的制造商进入。
在上个月在瓦伦西亚进行的季前测试中，电动方程式发布了其三角翼启发的Gen3设计的第一张预告图，该设计将具有470bhp和600kW的总再生制动能力。
新规则将于2022-23赛季开始，汽车制造商Spark Racing Technology的私人测试正在进行中，将在春季交付新机器。
接下来将是Gen3 Evo的技术改变。
但Gen4已经在考虑之中，新的制造商将被邀请为电动方程式的未来方向"集思广益"。
在接受Motorsport.tv采访时，冠军联合创始人亚历杭德罗·阿加格（Alejandro Agag）透露："Gen3已经令人惊叹了。
"但我们现在才开始考虑Gen4，它将在五年内推出。我们现在必须开始讨论。
"当然，我们将邀请现在与我们在一起的原始设备制造商和制造商。
"但我们也将扩大小组，邀请所有制造商以非常开放的心态对Gen4的外观进行头脑风暴。
"在那里，一切都是开放的。任何事情都有可能发生。
作为这种开放方法的一部分，电动方程式将考虑采用氢燃料电池技术为电动机提供动力。
Agag继续说道："氢气在FIA的电动方程式许可范围内（据称是纯电动单座赛车的独家25年权利协议）。
"使用氢气有两种方法，一种方法是燃烧氢气，这是非常低效的，但有些人正在努力使其更有效率。
"另一种方式，也就是我们将使用的方式，是氢燃料电池，它基本上产生电力，然后为电动机提供动力。
"因此，一旦这些技术开始广泛使用并在赛车水平上运行，我们肯定会研究这些技术。
Extreme E已经使用氢燃料电池为每场比赛现场的九辆Odyssey 21 E-SUV充电。
2020年，梅赛德斯技术合作伙伴HWA是宣布HYRAZE League概念的创始方 - 这是一款氢动力跑车系列，预计将于2023年推出800bhp汽车。
但Agag确实警告说，技术自由度越来越高会带来不断上升的成本，尽管电动方程式将在2022年10月1日生效的连续两个赛季中实施2500万欧元的制造商成本上限。
阿加格说："你需要给予这种程度的自由，这样制造商才能开发技术，并有理由参加冠军赛。
"平衡是关键。"
"但是你给予的自由越多，车队必须花的钱就越多，然后过了一会儿，他们就没钱了，他们就离开了。"

还行

眼光够长远，还得隔1年看到GEN3，这都开始GEN4了
