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.
That appeals to me in some ways, however I don't think I want to go back to the sounds of the previous cars anymore. I personally am not minding the sound these PUs are making. I also like these hybrid motors and their complexities! I say allow for more exotic materials to allow the manufacturers to make lighter cars.

1200-1400 bhp wouldn't be an unreasonable amount of power in these cars. The power to weight ratio would still be less than a 505kg 1994 Ferrari V12 with just short of 800bhp...

Before 1995 the minimum weight did not include the driver. Gerhard Berger weighed 74kg and Jean Alesi 72kg in 1994 so that's 579kg and 577kg total weight.

Where do lap records stand now that this season is nearing conclusion? Did the lower & wider cars prove to be quicker?

Ultimately faster lap times, year to year, aren't really a big concern for the sport. Have they ever been? The championship winner only cares if they are faster than the other teams. There are limits in terms of what the tracks can safely accommodate, and what the cars can withstand during a crash. Also, I doubt there's much interest within the sport to develop G-suits for use in land vehicles.

This would all be the purview of a new series.

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.

The W08 is "over 5.7m long".
