Yes, if energy can be made by the MGU-H it can be either sent to the ES for later use by either MGU (but the MGU-K may only use 4MJ per lap from that source) or the MGU-H can send energy recovered directly to the MGU-K. The only limitation is the amount that can be used at one time, which is 120kw (or 161bhp).<br /><br />2. It's broadly understood that the MGUK recovers energy under Matthew Somerfieldhttps://www.blogger.com/profile/13759263537936706584noreply@blogger.comtag:blogger.com,1999:blog-2239944414177437471.post-86063653810483814832018-08-15T19:19:59.984+01:002018-08-15T19:19:59.984+01:00as there is no "reply" facility to your ...as there is no "reply" facility to your answering post: "yes there is no specific regulations that suggest the MGU-K must only recover energy when braking".

The idea that Ferrari have managed to take the PU and reduce drag by stalling the rear wing is quite interesting and I can see that it's a pretty touchy arrangement. From a driveability standpoint that could really change up the balance dynamically. Can you tell me .. do teams program specifically for a given track or do they rely on programming the PU for general John Whitlinghttps://www.blogger.com/profile/00658051934611054181noreply@blogger.comtag:blogger.com,1999:blog-2239944414177437471.post-15281135561800831062018-08-14T14:12:16.351+01:002018-08-14T14:12:16.351+01:00I would counter that by asking 'what is breaki...I would counter that by asking 'what is breaking?' - everywhere where you do not need full power from the engine, you could still run it full tilt, and let the MGU-K sap/recover some energy until you get at the amount you need at the wheels.Anonymoushttps://www.blogger.com/profile/05765736099937240637noreply@blogger.comtag:blogger.com,1999:blog-2239944414177437471.post-9146161372617970822018-08-13T13:19:04.942+01:002018-08-13T13:19:04.942+01:00In one part of your article you infer the MGU-K is...In one part of your article you infer the MGU-K is being used to harvest energy other than when braking, is that allows by the rules/regulations?
