... the rules allow that only under braking. Any other means of recovery by the MGU-K, means 'extra' recovery over and above the 2mj per lap allowed by the rules.

Ispanol6. ''When compering with the FERRARI engine, the FERRARI electric motor (MGU-K) is listed as making 163 bhp/130 kw'' This is not possible according to the rules.....

the MGU-K can recover whenever the accelerator displacement has dropped (with or without brake pedal action)

in motoring the MGU-K can legally draw from the DC line at 126.3 kW
(because the '120 kW' rules assume 5% loss from DC power draw to mechanical power added to crankshaft)
maybe Ferrari just saying their MGU-K is rated ie safe to 130 kW ? - or maybe it's a typo ?
(a metric bhp is 735.5 kW but an 'English-speaking' bhp is 745.7 kW)
126.3 kW draw with 5% loss corresponds to a mechanical output of 120 kW/163 metric bhp

Goodness me - they have been using the ICE to drive the MGU-K!!!

If intended to mean 'driving the MGU-K by ICE power', the answer is no, as the MGU-K recovery rules does not allow that. Of course the MGU-K is actually 'driven' by the ICE crankshaft when recovering, but the rules allow that only under braking. Any other means of recovery by the MGU-K, means 'extra' recovery over and above the 2mj per lap allowed by the rules.

You should make it clear that this is only your opinion.
Honda has a different opinion.

Control technology since the 2014 season. Paragraph 6:
"Under partial throttle when starting to exit a corner, a different control technology called partial recovery is employed. It is used to generate electricity by diverting excess output to the MGU-K after the engine generates enough output to meet the driver’s needs."
