Scuderia Ferrari SF15-T

[PlatinumZealot]

The 2015 Mercedes HP gain seems to be dropping. The latest figure from AMUS is 40HP, though Lauda says its less. Not sure I would believe him though. If Ferrari have truly found 80HP, the deficit to Merc could be as low as 20HP.

From AMUS today:
'Especially not when you know that Mercedes has increased by 40 hp alleged. What Mercedes-Foreign Minister Niki Lauda denied: "Who was already at such a high standard as we are, is more difficult of zuzulegen "These figures are unrealistic 15 to 20 hp would be a great achievement..." '

He is right. Most of the other teams lacked mid rpm power more than peak power.

[Juzh]

He is right. Most of the other teams lacked mid rpm power more than peak power.

Sigh... this again? Please explain how are you gonna lack mid rpm power when rules dictate the same fuel flow from 10.5k rpm up to theoretical max 15k rpm. Utter nonsense.
Mid range power was important with the old V8s. It's irrelevant now.

[dren]

Alison has already stated they made gains with their energy management for better continuous power output during the race. They had decent peak power over one lap for qualifying.

Think again Juzh.
Mid range power is always important, makes a PU more drivable, improves acceleration, improves fuel economy.

Depends of what you define mid range.

[Chene_Mostert]

Well Juzh it is as the name suggests -Mid Range-, if you generally operate your engine between 3500 and 10500 RPM then the mid range would be about 6000 to 8000 RPM, generally were you would have your revs prior to accelerating out of slow to medium speed corners.
There is really no other way to define it?

This definition is false. Teams do not operate their engines between 3050 and 10500 rpm (more like 8000-12500). What I consider mid range are revs when you are no longer traction limited and accelerating at full power towards your maximum revs. This used to be important with peaky V8s which had "literally" no power under 17k rpm and gear ratios became essential, but is now obsolete because top power is constant. Mid-range effectively does not exist anymore.

But how engine goes from 8k to 10.5k? There was a notion that Ferrari engine suffers from poor driveability. IMO it means that it's not smooth accelerating from 8k to 10.5k. This is of course not the same as lacking midrange power.

Well then as you say,
So then the other teams struggled with power developed in the revs band when you are no longer traction limited and accelerating at full power towards your maximum revs. - Most would just say they struggled with mid range power.

[Henne]

To early to be optimistic but the car looks better on the track, the engine sounds more powerfull and cleaner. And the car seems to be more constant on the corners. But it SO early!

The fast lap says nothing, of course.

Frankly, your observations are correct, and while it's early to draw conclusions, it is a sign that the team has taken previous woes seriously. Having a pretty stable car performing on this levels certainly means you have done something right. Whether that is going to be enough to reach your goals - time will tell.

Car looks a lot more 'simpler' too talking about aerodynamics... But its early to draw any conclusions, way too early

[Juzh]

This is of course not the same as lacking midrange power.

Yes, correct.
There are basically just 2 states of power. Either you're traction limited, at which point you're not at full throttle and so called "mid range" doesn't matter anyway, because you're demanding less than what is available from your PU. OR, you're at full throttle and above 10.5k rpm where power is constant.

Example:

The blue engine has more mid range power than the red engine...

In this case most would be wrong in that assumption.

Sorry, but this is not a valid argument. You can't compare a nissan gtr engine to an F1 V6t.

huh? Tell that to any racer.. any real racer, and they would just laugh at you. As long as your tyres can take it you need as much power out of the corners as you can get. Waiting for 11000 rpm is not an option.
