Here's something they are scratching their heads over at f1technical. The Red Bull was fastest in the speed trap yesterday, which is not the usual RB way of slower on the straight and faster on the bends because they have the downforce sorted, and good going for something with a Renault (TAG Heuere) engine. These photos show the RB and Mercedes on the straight, with the rear end squatting down. That's fair enough for the Mercedes because the DRS wing is closed, so it's got full rear downforce. The RB has its wing open, and the standard ride height for it has its rear end in the air, and they've got it to squat at least as much as the Mercedes.



Might be an aero trick? They are trying to work out what the hole in the nose does too.
Both Red Bull and Mercedes are running a hydraulic ride-height stabilisation system with generates hydraulic pressure and then deploys it to set the car's ride height, and equalise the ride height in roll. It's the system which Ferrari asked Charlie Whiting to clarify at the end of last year, and the likely source of a protest in Melbourne.

Hole in rb front end is just to reduce surface area and get more air under the car.

Exact same design as the tusk nose lotus.

Those semi-active suspensions are IMO aero devices and shoiukd be killed. All they do is widen the golf of spend o the grid.

On the pother hand, in s f1 active suspension would come back - its road relevant and interesting.

I thought there was a lot more snippet around yesterday, common sense prevails.

Also McLaren made it all the way to the end of the pit lane this morning before breaking down.

Seems the McLaren issue yesterday was the oil tank not being the correct shape.

Mercedes running a double front rear wing today.

Hamilton also said the tyres last a lot longer than they did before, but he thinks passing will be harder this year.

Baku and the turn beside the castle will be interesting with the new cars we have...

Any suspension is an aero device, if the suspension moves, you alter the chassis attitude.

The suspension on these cars is not semi active, its passive. They are just being very clever with the hydraulics.

Any damper and spring system can be setup to give variable ride heights depending on aero load or spring frequency, its been done since the ark with spring rate, valve rate, bump stop design and packing.

Gary Anderson implying on Autosport commentary that tyre deg is still very much a factor, suggesting that Pirelli have not succeeded in significantly toughening up their tyres. This is a bad thing.
Looks like he's barking up the wrong tree on that one. A few drivers have already said that they are able to push harder for longer.

Ham has just done a 19 lap stint on softs and only dropped off a second or so.

McLaren 5 seconds slower a lap than a Merc and second slowest in a straight line yesterday. You can argue its still in test phase but...

I'd imagine they are just pleased to get round a lap!

Mercedes bust out the super softs and Hamilton does a 1m20.983s. Impressive.

And 0.3 seconds slower in the last sector than his PB on soft tyres. A lot more to come yet

Pretty embarrassing considering that this is the third year of the McLaren & Honda partnership!

Mercedes are looking impressive.

But compared to last year, where Ferrari went through piles of soft tyres, they are sticking to the mediums.

They are certainly keeping their cards close to their chest for now. But they have decent enough pace and are racking up the laps pretty painlessly.

They have certainly closed the gap if nothing else.

And reliable so far, so they can get through the whole testing program to correlate against their models. A good sign.
