That is part of it, regenerative braking - and yes, the energy being
'recovered' came from the ICE.

It's not just to charge the battery - it's also to keep the turbo spooled. Now
they don't have the
MGU-H to pre-spool the turbo there is a lot more off-power revving going on.
Standing starts are a
lot noisier now, they're revving for a full 5 seconds to build boost before
dumping the clutch.

As well as the extreme downshifts during the first test a lot of drivers were
locking up / over
shooting corners* as so much more of the braking is being done by the rear
axle / MGU now. (I don't
know why they didn't go the whole hog and put a GU on the front axles like
Formula E have but
that's another story...)
Also there is what the teams are calling 'super-clipping'. This is where the
ICE is revving /
working and producing far more power than the car needs for forward movement
is slow speed areas.
During this phase the ICE is actually having a large chunk of it's output bled
off (braked) by the
MGU to charge the battery.
My peeve was that the pundits were saying that the power was being provided by
50/50 ICE and MGU.
It wouldn't have bothered my if they'd been saying it was DEPLOYED 50/50 by
ICE and MGU.
With the 25% reduction in amount of fuel allowed this year as well as it being
fully 'sustainable'
and no MHU-H to pre-spool and harvest I think this is going to be a step back
for F1. Definitely in
regards to lap times.
Also I've got a fair grasp of technical things but the removal of DRS only to
replace it with
'overtake mode' (an electric boost they get if they're within 1 second of the
leading car at a
single detection point for a whole lap) seems silly.
Then there's the movable aero. Two modes, straight and corner. If they're
keeping a passing aid
when within 1 second of the leading car why change from the old DRS? It's
largely because there is
much less power available to cars this year so to keep lap times remotely
respectable they need to
be able to bleed aero drag on every straight.
Then there's 'boost mode', a tool that drivers can use any time they want to
attack or defend (can
be used in conjunction with 'overtake mode'). The downside is it drains the
battery more. This
seems superfluous to me - why complicate things with THREE 'go-fast' modes?
This could just be part
of the software and not need to be talked about IMO.
As if the cognitive load on the drivers isn't increased enough this year
there's also three
different flash codes from the cars tail lights now. Single fast flash, double
fast flash and
triple fast flash all designed to impart information to a following driver. So
now as well as all
the other settings they're dealing with they're expected to spend more time
watching the rear of
cars ahead?
* So the reason a lot of drivers have been over-shooting corners under braking
is that the software
is dynamically adjusting how much braking needs to be done by the rear axle to
maintain the SoC
(State of Charge of the battery) lap by lap. So if a driver's been braking at
the 50m marker with a
60/40 front/rear braking split and settled into a groove, then he uses boost
mode as well as having
had overtake mode for a lap next time he comes to that corner the software
decides the battery
needs a 40/60 front/rear braking split. Result? The car doesn't have the same
braking performance
and if the driver brakes at the same marker he goes wide or locks up - or hits
the car he's trying
to overtake. To me this is shades of Bernie's turning sprinklers on randomly
to spice up the spectacle.
I really enjoy F1 but at this stage of the new regs this all seems a bit too
much Mario Kart++
