2017 F1 general testing thread

That sounded like serious metal crunching in that Honda motor, of the hole in piston or bearing gone variety.

Bottas quicker than Hamilton on the softer tyre. That lap from him yesterday was very special indeed.

Do please share the cars respective fuel loads and setups since you think you can directly compare these two laps.

It was one fast lap I believe, what would be the point in doing one hot lap on a heavy car?

Getting data points in a wider area of variables. It helps mapping out behaviour of the car. During the race they can't choose the fuel load, so they could be trying out a variety of situations. For instance the start of the races usually are done on the softest tyres, on heavy fuel load.

Not saying necessary this is the case, but like Shakeman tries to explain, it's not possible to directly compare those laps. These are none-competitive conditions trying out a wide range of competitive conditions. Or in plain english: we don't know.

No one is doing low fuel laps. This is not qualifying!

This is testing and the teams are working on setups for the races and high fuel loads.

Renault also changing engines, it seems like neither Renault nor Honda have their formula right.

Not the entire time, that's why laps variate from 1. 25 to 1. 19.

[marvin78]

That's no the only reason. There are so much variables, that cause this variation in times, you can't put them in one post

[PhillipM]

Yes, it's also why they're sangbagging on fast laps and still aren't running flat out yet. As per yesterdays discussion where I got told they don't do that, they go flat out!

Well it's as plain as the day is today...they sandbag.

Sure i can, high fuel loads, fresh tires and engine modes.

[Wass85]

Of course they are doing low fuel runs, they might have slightly more fuel than a Q3 run but they are running low nevertheless.

there's a huge difference between a second or third stint fuel load to the egg cupful in Quali. We've no idea if DRS was used in these laps or not or for how long, how much down force the cars are setup with. There are way too many variables to make a comparison between two laps on two different days during testing which Wass85 was doing.

The quick times are not an indicator of quali setup in a grand prix weekend. IMHO.

[marvin78]

... specific Test-Program and other factors, like weather, wind, temprature changes etc... They are really countless.

From Sky Sports' "The F1 Gossip Column":

Have Ferrari found a loophole in the 2017 regulations to steal a march on their rivals?

'In recent years, Ferrari had been accused of having built a conservative car,' an article in Auto Motor und Sport states. 'Not this time.'

Comparing the sidepods on the SF70-H to their rivals' challengers, these appear much higher with several flow aids in front of them - but the German publication's Michael Schmidt writes that these side boxes, while following the FIA regulations, are attached to the real side pods which are hidden behind.

The FIA incorporated rules about what angle the side pods should be, and paragraph 3.8.8 says that that angle should be 75 degrees. This is purely to aid aesthetics - aerodynamicists would prefer the angle be 90 degrees to help air flow. All other teams' sidepods are 75 degrees - Red Bull technical chief Adrian Newey is said to be baffled by Ferrari's idea, while Mercedes are one of many teams who raised their suspension to clear a path for air to move under and around the sidepod.

Now, here's where Ferrari's loophole and possible advantage comes in. The carbon work in front of, and attached to the sidepods, is 75 degrees, thus following the rules, and this allowed Ferrari to make their actual side pods much smaller. It also allowed the Scuderia, under the guidance of technical chief Simone Resta, to make them at the desired 90 degree angle.
