    Lightbulb The F1 Technical Thread

    I created this thread to try and get some sanity back into a thread about the motor sport we love so much.

    Like there are rules in the Guns, Ammo and Hunting sections, I propose a few thread rules here, regarding what is to be discussed and posted:

    1. F1 cars, teams, tyres, new innovations, strategies, tracks, etc (you get the idea).
    2. Other motor sport news etc. (from time to time).
    3. New regulations.
    4. NO discussion about any driver or team member's personality, dress, looks, race etc.
    5. NO name calling of drivers, team members, or forum members.
    6. Only images of technical nature.


    If you are prepared to stick to these rules, please contribute. By posting here, you agree to the above guidelines.

    If you have a urge to post other matters relating to (what you consider to be important re) F1, please do so on the other thread.

    I will take it on myself to report any post that does not comply with this thread's purpose.

    Seeing as this is more technical. What is the story with 4 engines and what penalties do you get for changing engine.

    I am asking as RB are thinking of using this weekend and the penalty already given (3 places - not debating this) to sort of make the best of a bad situation

    4 engine restriction is an attempt to keep the costs down. Otherwise teams like Merc/Ferrari/RB would burn an engine every race.

    The penalties (10 grid places off the top of my head) are supposed to discourage taking more than the allocated amount.

    Problem is that Merc/RB are so dominant they can take 10 grid places and still carve through the midfield to get podiums. Like Bottas/Perez did in Italy.

    My solution to what has become an irritatingly boring farce...

    Only 3 rules

    Cars to be 1.5m shorter than they currently are.
    All to use the exact same braking components
    As for the rest, entrants to do whatever they see fit as long as they use an internal combustion engine

    Do the penalties stay the same for a 5th or 6th engine? (Thinking about what if there's another accident that requires a new unit).

    It is actually a three engine restriction:

    ICE – internal combustion engine, TC – turbo charger, MGU-H – motor generator unit heat, MGU-K – motor generator unit kinetic, ES – energy store, CE – control electronics, EX – exhaust system.
    In 2021 F1 season, drivers can use 3 ICE, 3 TC, 3 MGU-H, 3 MGU-K, 2 ES, 2 CE and 8 EX.

    Thank you.

    Help me understand Max current position. He has used his 3rd engine in Hungary so based on the following copied from the links in post 1.

    ith 23 races scheduled for 2021, here are the allowances for each component this year:
    Internal Combustion Engine - 3
    MGU-H - 3
    Turbocharger - 3
    MGU-K - 3
    Energy Store - 2
    Control Electronics - 2
    Teams can mix and match components throughout the season, but needing to use any new component from outside this allowance will result in a grid penalty. These parts cannot be changed once qualifying starts. If a driver needs a new power unit or ERS element after qualifying, that driver will get a grid penalty or could be required to start from the back of the grid.

    When does he get a grid penalty and when must he start from the back. If he already has a 3 place grid penalty will a new engine not result in just one more grid penalty?

    Reality! Uber.

    I am also not clear on how many places a "grid penalty" involves.

    Did Botas not start right at the back because of a new power unit?

    Can Max's engine penalty and infringement 3 positions run concurrently?

    The problem with the cost argument is that it is SUPER expensive to make a high performance engine last so long. Its actually cheaper to make 5 engines you turf after every race than engineer and build one to last 5 races.

    In the heyday of the previous turbo era, they would build a qualifying engine that lasted 1 flying lap nevermind a race weekend.

    I think so, otherwise Mazespin will never be able to be penalised.

    Nope, example Gasly crashed in the sprint race at Monza so was going to start last anyway so the team fitted a new engine (even though his was fine) because the penalties do not compound. I.e. they got an engine replacement "for free".

    A little add-on.
    A used engine is allowed to be re-utilised later in the season when overhauled as long as:
    - all the original main components are present in the rebuild
    - all components were registered with FIA before the first deployment

    This means a team can store an early season engine for later use and get away without a penalty when bringing it back.

    I agree 100% on this one.

    A current generation F1 car like the Mercedes is longer and wider than a current S-Class Mercedes, they are also heavier than they have ever been.

    People complain that the tracks are not conducive to racing, the absolute size of the current F1 cars prohibit close racing on most of the classic racing tracks.

    Ferrari did just this last weekend. They replaced Leclerc's troublesome power unit with a previous unit.

    "Yes" they did. It didn't seem it would have lost some of its grunt.

    I wonder anyway at what the loss of output would be from original to say after 5 race week-ends.
    5 race week-ends would possibly ad up to around 2500kms.
