Aye, those were the days. Back then you could stop in the middle of nowhere on a dark night and tell the girl that you had to wait for the car to cool down, so we may as well "get comfy". These days they call it "inappropriate behaviour" and expect you to resign from parliament. It's PC gone mad...

Finally; something we can all agree upon, with a smile.

Are you smiling at me? That's inappropriate sexual coercion - I demand your immediate resignation!

"The beams of your smile entered my space and touched my heart via my left breast." You pervert. Off with your head: oops I meant hand; can't mention head and you in the same sentence.

Thanks for that david - I spent a couple hours and watched all the segments - good stuff (and probably as close as I'll get to having a beer with Niki ).


I recall when the current engine formula was introduced, everyone was tracking fuel used. There was even a display where, instead of their time gap, it would show fuel used - and the commentators speculating that driver x was over budget and would have to back down, or driver y was under and could push harder (not to mention Mr. Smiley getting DQ'ed from a podium at his home GP due to exceeding the max fuel flow rate).
Now I don't hear anything about it

From McLaren and Alonso's point of view, what do the goodbye Honda and hello Renault power units have in common?


Unreliablility. Still, Renault-powered Red Bulls are occasionally darting in and messing up the fight between Mercedes and Ferrari, so expect bursts of interest, even shark frenzy at times?

Let's get Mercedes, Ferrari, Rad Bull, perhaps one other; allow them 3 cars each and have a race series. Then all the others could have their race series, on the same day at the same track, but earlier. A sort of GP 1.5. Max was so far ahead of 4th last week that there were 2 races anyway. This way there are less cars on the track, they might all stay closer together and there might be more overtaking.

Ferrari have considerable previous on threatening to leave. And that is just what was made public.

This is one of the ways how Ferrari has received special treatment in the past, I suspect. They think they are F1.

It would be rather un-F1-ish without them.

Someone else, like Renault, or a new player like Alfa would surely step in and paint their cars red, and it would be back to racing. Gotta have a splash of red on the grid!

I believe that the MGU-H is a sort of electrically-driven turbocharger that can absorb power from the exhaust and generate electricity which is passed to the battery for storage - but can be 'recalled' to propel the turbocharger so as to negate turbo lag. So why is it a good idea to do away with it from 2020?

Go back more than half a century and you find a lot of aero-engine companies working on a concept called "turbo-compounding" in which an exhaust-driven turbo-supercharger had its rotor mechanically connected to the crankshaft so that the excess exhaust energy in the cruise could be extracted to do work rather than being "dumped" through wastegate systems. Many of the larger 1940s piston engines had turbocompounded versions (the 4360 twin wasp major being a good example), but the idea was obsoleted by the arrival of jets. The idea was also played with in cars and trucks where the mechanical coupling also eliminates turbo-lag, but it's difficult and expensive to do it right in a way that is reliable enough to be worth the effort.

Scroll forward to around 2010 when the hybrid engine formula was going through its concept stages. The fundamental idea of the formula was to use the vast development budgets of F1 to find ways to make infernal combustion engines more efficient. They'd elected for turbocharging (because that's an essential part of an efficient IC engine), and the idea of turbocompounding was attractive for making it even more efficient, so they decided to do it in a "modern" way by compounding it "electrically" via the hybrid system rather than with mechanical clutches and gears.

So the MGU-H is a Motor/Generator Unit which is on the shaft of the turbo. It can extract energy to charge the battery, and it can also be used to keep the turbine spun-up at low throttle to eliminate turbo-lag using power from the battery. In principle it can also be used to drive the compressor directly (becoming a mechanical supercharger), but this isn't very efficient and I understand it's rarely done (although I'm told by one source that this is also part of the Mercedes "magic qualifying mode" but I don't know if that's true).

Almost all of the energy extracted by the MGU-H (and there's a LOT of it) is "used" as mechanical drive, delivering torque into the gearbox via the MGU-K. A failed MGU-H is a big deal, losing a net 150-200bhp from the peak power available to the driver. The MGU-H also has a secondary function in that it is used to "regulate" the turbo's rotor speed. This allows them to run the turbo well into its surge island with impunity, making the whole thing even more efficient. So the MGU-H is an important part of this >900bhp, 50% thermally efficient power system - essentially you couldn't have the power or the efficiency without it.

The FOM proposal is to eliminate the MGU-H and recover the lost power by allowing more fuel and increasing the rev limit. The engine manufacturers don't want to do this because increasing the fuel consumption (reducing the efficiency) is the opposite of the whole reason why they're doing this F1 malarky anyway, and because the increased rev limit will require a complete redesign of the engines to cope with the extra stresses. They also don't want to add the weight of extra fuel to what they already regard as overly heavy cars.

Personally I think removing the MGU-H would be a silly thing to do. They will be starting to appear in hybrid road cars next year anyway, and they are a key part of the whole PU concept - they are what makes them technically seriously cool!

They may have something of a point.

Problem is that so many people paying to attend Grand Prixs or watching them on TV also think so.

Much as I hate to admit it, F1 would suffer greatly (terminally?) if there was no Ferrari participation. Ferrari say that F1 is in their DNA. Likewise, after 50+ years of following F1, I consider Ferrari is in the DNA of F1.
