McLaren have chosen some interesting design routes on their new competitor. In addition to our own technical analysis, McLaren's Tim Goss and Paddy Lowe explain why some decisions have been made in light of the regulation changes.
Not sure - But I'd like to think they would give it a try.jason.parker.86 wrote:Do we know if / McLaren intend on introducing a new exhaust system and/or a new suspension.
Yes new exhausts have been seen in the prototype area by the person I know at mclaren. They have heard they are low exhausts and the suspension is being changed too.dannyteasdale wrote:Not sure - But I'd like to think they would give it a try.jason.parker.86 wrote:Do we know if / McLaren intend on introducing a new exhaust system and/or a new suspension.
There is apparently a brand new car coming to Silverstone so who knows. Although its only rumoured.
JB we know , who is LW ?ChrisR20XX wrote:LW: "It works... so eeh"
JB: "Do you wanna take it out first?"
LW: "Naah i think we leave Gary to do it"
JB: "Yeah, thats what test drivers are for, isn't it ?"
LW: "Yeah exactly"
so great ^^
It is not quite as easy as that! The exhaust pipes have to be tuned and balanced to be compatible with the engine. It takes some time to achieve this. And further, some ancilliaries may have to be repositioned due to being closer to exhaust heat, extraction airflow, etc. Ferrari have acted promptly, but i think that mclaren have been wrong footed. Their f-duct has been designed with particular airflow through the diffuser, and messing with the diffuser, could negate some of the benefits of the f-duct. Ferrari had NO f-duct, hence it is less of a problem for them.ringo wrote:It wouldn't take much out of mclaren to lower the exhausts, based on the current design. Nothing needs to be repositioned to accomplish it; just new pipes and paneling.
One thing that may be completely new is the bridge wing panels that make up the huge upper deck of the diffuser.
Maybe he meant LeWis Hamilton?lotus7 wrote: JB we know , who is LW ?
The f duct doesnt pass any airflow through the diffuser!? Also Ferrari do have an f duct!?gilgen wrote: Their f-duct has been designed with particular airflow through the diffuser, and messing with the diffuser, could negate some of the benefits of the f-duct.

The tuning is dependent on the length. I doubt they will have a drastic change in the pipe length. With the software capability, and the engine load and flow data, i doubt it'll take a day to have a new layout ready for manufacture.gilgen wrote:It is not quite as easy as that!

The diffuser handles under car airflow, whilst the f-duct handles airflow over the wing. The two are complementary! You cannot change one without affecting the other. Mclaren went for controlling the higher airflow. Increasing lower airflow, and removing exhaust flow immediately below he wing, could cause aerodynamic inbalance.thestig84 wrote:The f duct doesnt pass any airflow through the diffuser!?

Rival engineers also believe the layout, pioneered by Adrian Newey, allows air to be channelled more efficiently into the downforce-producing double diffuser. The system is believed to be worth up to half a second per lap.
"We have a reasonably big upgrade that we are fighting to have for Silverstone, and if that is there then I would be disappointed if it is not a much bigger step than that," said McLaren team boss Martin Whitmarsh.
