Nice technical summary from Scarbs as to Manor's need to do things towards integrating the Mercedes engine and Williams transmission and suspension. Quite a lot of work for the team, but the components are there.
We already know quite a bit about the direction Manor were going to take, as we saw the unraced 2015 car wind tunnel model. This was going to run the Ferrari rear end with a shorter wheel base (than the 2014 car), by removing the roll hoop mounted oil cooler, to allow the fuel tank to be shorter and taller. The oil cooler being repositioned STR style with rhomboid cooler flanking the engine.
We also know the team will now run the Mercedes PU with the Williams gearbox and suspension. The Merc PU set up is different to the Ferrari, Merc place most of the ancillaries in front of the IC engine, meaning the fuel tank needs lots of relief to fit the compressor, airbox inlet, control electronics and battery. Ferrari pretty much only house the battery in the fuel tank area, allowing a short tank thus pushing the engine forward along the wheelbase. Ferrari also provide the Mezzo water intercooler, fitted in the V of the engine, as opposed to the Merc customers who tend to run air intercoolers in the sidepod. Countering that slightly is Ferrari’s larger electronics package which goes in the sidepods.
So Manor’s challenge will be to get the desired wheelbase and engine position. Mercs own powertrain set up is quite short, so using Williams gearbox should mean the length is greater by having a longer gearbox case. So the tub will no doubt have to retain a longer fuel tank, with a large space underneath for all the Mercedes gubbins. We haven’t seen a roll hoop fed oil cooler on the Merc PU installation, the Merc has a very bulky plenum, but the concept could work and will free up space in the sidepods. No doubt the Merc ERS water cooler will take its customary position above the gearbox, again fed from the roll hoop.
The front of the tub needs to be cleaned up from the interim 2015 spec, I’d be surprised if they go for a short nose, due to the resources that will suck up to get past crash testing, unless there’s some Williams cooperation there. As Williams have a very clever and different nose structure to all the other teams. The inboard suspension, will need developing, as the teams fledgling FRIC set up using telescoping pushrods was discarded and a parts bin set up refitted to the car when FRIC was banned mid 2014. I doubt they’ve had time or budget to develop this area in 2015.
This will be critical to manage ride height for a more raked set up. As will time in Williams tunnel developing the aero, which is still quite a step behind most of the grid.
This might be a stupid question. Why did they choose some bits from the Williams car and the engine from Merc? When it makes it difficult to fit together? Especially if they're going to be a Merc B team. Is there some, 'best of both worlds' thinking going on? Or is it ' you put the Williams in,the Williams out, the Merc engine in, And you shake it all about! '
So they're getting support from Williams because they're buying ' suspension components'. And they sort of fit with the Mercedes engine because Williams have one too. All good so far! But I've heard the fit isn't that brilliant, there are some issues, because the shape of the car is a bit different. So wouldn't it have been better to get the whole lot from Mercedes and the support from them too, especially if they're going to be the merc B team ? Unless they can somehow do a genie thing and make it fit together even better than the Merc.........which isn't likely. ( I added that last bit before you could!)
Some people say that Williams has the best transmission in the business. I think the idea here was to have Mercedes focus on what they do, engines and pawn off the support to Williams since there's much more to be gained by Manor from simply getting a competitive and well sorted chassis.
I think it's the best they were going to get. I don't think at this point that Merc was in the B team business if they could have Williams shoulder some of the burden. Any help they get will move them up the grid and Like I said, it's not like they're getting crappy components from Williams.
They can always revisit the relationship in a year or two. I also don't think that Haas will remain Ferrari bound forever if they really get to a point where they'll want to spread their wings.
When you are torn between choices, always pick the one that will make the best story. ¯\_(ツ)_/¯
