Mercedes AMG F1 W05

[Boost]

I don't think so, I have never seen post turbo air temps as high as water rad temps so there is no way you could cool the pressurised turbo air with water from the radiators that also cools the engine, just no way, now if it is a discreet system separate from the engine cooling system then yes but that would be less efficient than just cooling with ambient air.

Most road cars run water temperatures of around 90°c whilst the turbo exit temperature will generally be in excess of 100°.

The old Escort Cosworth actually had a two stage intercooler. The first bit was water/air and used the engine coolant which was able to knock a good 30° off the charge temperature in a very short distance. The charge air was then passed to a more conventional air/air IC.

An F1 engine is probably running 120-130*c water temperatures, not 90*c.

Good info, just that I have never seen compressor outlet temps at 100c, even boosting to 50 psi

afair there is a pressure limit that limits the water temperature to 135*C and they run as close as they can (atleast they did with the NA engines)

Can we get this thread back on track?

Technically speaking, how is it possible for Mercedes to find that pace with the W05? It surely isn't engine-related. McLaren have the firefly suspension and Williams have their nano gearbox and all that open space in the back... so what is it about this car that it makes it so special and good aero? Where's the trick?

If you compare the level of refinement and ingenuity of the W05 with the other cars, you can clearly see this car been developed over a longer period. We all heard the stories about how Merc wanted to win in 2014. They have obviously put a lot of effort in to this car. At the Jerez launch the difference between the level of detail compared to the other cars huge. When i saw to amount of detail the front wing an the suspension had compared to you could tell that the car should be competitive. The eye for detail compared with all the W0's before was night and day. Also the nose of the car, not like most teams choosing the easy option and choose for max air flow for the diffuser, Merc uses the nose the create down force. Little things like that makes the car go faster.

I'am most proud about the fact that they finaly sorted their tire wear issues. Because the W04 could have challenged for WC last year a lot of poles put the tires holding it back. Now they got it all sorted qualifying pace and race pace. A lot of credit must go to Costa, Bell and Willis because this cars looks fast and goes fast, a real silver arrow.

Something funny is going on under the Merc's nose. Also notice the Zr protection on the upper side of the crash structure

Do you have the 4th picture in high res? Thanks.

Here you go. The carbon panel under the nose is directing air towards the T tray

I don't think it's any one particular area - it just all works well together. The Red Bulls of the last few years have obviously been dominant but they never really had any particular trick up their sleeve which made them so much better. They cracked the EBD better than everyone else but that's just like Mercedes have cracked the engine better than others.

I mentioned earlier...but will that hull shaped part covering the CS beneath the suspension arms be better at interacting with the diffuser than say the RBR or Ferrari's 2d curve?

[Powershift]

is the crash structure not at a very regulated height? And with Kobay submarining under Massa's rear yesterday you would think the rules makers would make sure the front nose and rear crash structure were a uniform height so we don't see such a thing as Massa's rear crash structure in Kobay's face

also the placement of that "cooler" on top of ferrari's gearbox(in the previous pic) seems strange, would not the exhaust pipe be taking up that space by regulation?

You're looking the wrong way.

Regarding the new front wing not used in qualy, it seems to be that the odds are in favour of "FW doesn't match this nose like the one Merc are designing" instead of "Merc prefer to go with a wing they know better"

The new nose will be shorter, so that the under-the-nose airflow will be more energized (since there will be less space between nose tip and t-tray zone, the flow will be steadier) given the new level of pressure created, hence more rear downforce.

The gaining from the new wing in front downforce could have been unuseful compared to the (probably) unchanged rear downforce

What? What way are you looking at it?

ok, makes much more sense now

Elaborate this phenomena? Proof for your statement!

The devil is in the details. This car looks very developed as is. The internal packaging looks to have gone a step forward compared to the W04. Look at the carbon fiber casing under the radiators. The rear of the car is very open and clean. Just a good overall package.
