2018 whopping car weight

Post by Javert » Fri Sep 01, 2017 4:44 pm

Mandated by the rules it will be 733 kgs if the tires stay at the same weight

However, given the difficulties by teams this year in respecting the weight, the introduction of Halo and only 3 engines in season (that means more weight for , I would assume a right call would have been around 755-760kg!

So will we see that whopping limit or it will be sticked to 733 kgs?

3 engines a season? What are they hoping to gain for with that? Reduced cost?

Only if it's for customer teams, and still only maybe.

733 is already because of the halo why would they 750?

Either way ridiculously heavy cars.

Break the world record for blowing up engines on the dyno.

Because cars have had difficulties this year with weight, without Halo, with 728 kg

I can remember Mercedes, Force India (and Red Bull??) quoting they had difficulties with weight

Almost impossible they can respect 733 kg next year .. So expect a political move before end of year :) :)

Of course you have issues reaching minimum weight if your car is 20cm longer than the rest

And 4th and 5th and 6th suspension elements, transformer-like body-work, money seat, batwing, batfunnel, internal aero work, brake ducts, variable this, variable that... if affects all teams, actually.

The regs force them to a minimum weight and a certain weight distribution... it follows that there is more to gain by having advanced systems and extra bodywork than by lowering the center of gravity by 0.01mm. So they all add hardware until they are just at the minimum weight.

It is a vicious circle, because the team that has 400 million less to spend won't be able to fit the last piece of hot hardware while staying under the minimum weight, so they fit it anyways, complain, and the minimum weight raises... cue the top teams adding yet another suspension element with yet another hydraulic line and yet another 20 sensors for the extra allowed weight...

They could slash the minumum weight to 700kg right now, halo included, and the only consequence would be that all cars would have to become 50 cm shorter and 1 second faster (due to the reduced weight). But politics...

Not a photoshop expert, but this is a layman crunch of the W08 I could do. Why do they increased the length and width or the car? That in turn increased the weight. With 2021 engine rules having been revamped, can they not revisit the rules for the size of the car? That would save hell of a lot of the weight and make the cars faster.

F1 cars are already massively overweight to what they need to be. Ballast is added for almost all tracks and there is a substantial amount of excess weight contained within specific "bits" of the car due to their own specific regulations. For example, the energy supply for the MGU-K and MGU-H systems is around 20kgs (give or take) and stores upwards of about 7MJ of energy. Cars can only use 4MJ per lap and excluding the 90/10 law for battery charging etc, that is still quite overrated to what it actually needs. They are also overengineered with safety in mind as well.

733kg is heavy though.... Allowing 30kgs for the halo though - I dunno why, but I didn't think it would be "that" heavy... :shock:

Add another 125kg of fuel at the start in 2021 and these cars will weight more as a small city car.

Funny how technology keeps advancing and yet everything becomes heavier..?

Taking one figure out of context doesn't tell much. Lap times are as quick as ever.

Lap times SHOULD be quicker than ever, it's 13 years after the V10 cars and they are running huge rubber and 13 years newer aero development. They are actually slower (typically) during a race lap due vs the V10 era to the absurd competition weights.

Here's a devil's advocate formula. What if you took the 2004/2005 rulebook +/-, and gave them the same fuel flow limit as the hybrids, and gave them current tire size. Engine and comp weight was open with only the fuel flow limit in place. I bet they could run the same or quicker lap times in sub 600 kg cars with 1/100th the complexity of the modern PU.
