Mercedes due PU upgrade for Canada?

[TheDeuce]

Rumour from a recent Autosport video: https://www.youtube.com/watch?v=SV0khCjvAmI

It would be due - their two competitors have had PU upgrades, and they have not. Last years was planned for Canada too, although pushed back to France. Obviously it can't come soon enough as they've really struggled this season..

It's an interesting proposition, the idea that the Mercedes could end up being able to match Ferrari pace, in addition to already being stronger in every other area. Ferrari have already rushed through their first 2019 update, which was probably originally planned for Canada too - so it's unlikely they will have anything new for a couple more races yet.

In other news - Edd Straw now appears to be larger than the sofa he's sat on in that video. Perhaps just an unflattering camera angle

1030 + hp in race trim... quali trim (?)

It’s going to need to do 5/7 next races which are throttle heavy.

They might save it for France.

Maybe. Either way they must be pretty confident as the pre season PU completed well over a third of a seasons worth of laps.

What hp did they get from last years first upgrade?

Race trim 990hp (equiv).

What was the increase the update achieved? I think they started the season with about 950, so that would be a ~40hp increase. That would be significant if they managed the same increase now.

Do the teams have to publish the power output at all?

These are estimates the Pu range (ice) last year was 750/800 hp, and in the ERS then your looking at 160/200.

So yes I don’t think they’ll wring any more out of the ICE.

However.

Ferrari are getting there gains using bi metal alloys in the ice with clever fuel.

& Renault have made significant gains now there using the same fuel for race and dyno.

I think the next real gains are in understanding the electromagnetic drive in the MHU K, and how it can do more than it can now.

Hmm.. I wonder if there is more from the ICE too. Can't be much more, but reliability has been amazing for the last few seasons, which would suggest a little more is possible without risking meltdown.

It's quite amazing to think that the PU's are now likely meeting/exceeding Bugatti veyron power levels yet are only 1/5 the capacity.

Think fuel flow, and 105 kg limit.

These things are quicker than the v10’s (over race pace & quali) carrying the fuel, and electrics etc..

Jenson did a side by side at Barcelona in the Sky Pad, I’m sure the hybrids were 4 ish seconds quicker than the V8’s (fuel adjusted).

If he took the fuel flow limit away we would see more power & pace extracted.

No harm introducing it for the 7th rather than 8th race, as the first PU can do it's 7th race in Hungary.

Will add some extra spice if it's less than 100% reliable.

Or a further increase in efficiency. Their first hybrid was 44% thermal efficiency, in 2017 they exceeded 50% (almost unheard of), since then no figures but they have more power now and don't seem any thirstier. They must be close to the limit of what's practically possible now.

I bet there's a bit to come from the elctrickery side and how it all integrates.

I wonder if Ferrari still have their interesting battery set up?

Whatever they're doing, no sign they have a power advantage over Mercedes this year.

The ‘virtual’ energy store was judged as unsporting..

Will someone find something else, and get away with it..oh yes...
