Looks fine to me.

What is the impact on suspension design in having significantly less sidewall?

Unsure at present, I though the tyre move was to do with being able to follow, although suggested so far, the wheel rims will be standard/standardised, hydraulic suspension is to be not allowed, the return of active suspension was rejected, and the tyres will be manufactured to degrade less. In this particular area of the new regs, what will be interesting is how they get the best out of the suspension/tyres under ground effect aero.

I thought the low profile tyres were all about marketing as they're more closely related to what the public have rather than being anything to do with solving the "following" problem?

What are the flaps on top of the front wheels for?

That’s part of it, but the teams also expend significant amounts of effort trying to engineer their way around the inherent wobbliness of the fat tyres.

I too am pleasantly surprised by the appearance of the lower profile tyres.

Looks good to me. Is the overall diameter increased? Visibility issues etc?

So Sergei did 94 laps with the 18 inch in the Renault.

And Ocon did 106 laps with the 13inch (same as now) but 18 inch ‘compound’, in the Merc.

Both going again tomorrow..

Currently the tyres are the suspension, the teams would generally prefer lower tyre pressures.

The purpose of what we think of as the suspension components is to present the aero to the air in the most favourable manner. That’s why a common active suspension would have been a good idea.

So it is a lot more than just bolting different wheels on with a different compound. Everything will need to be re-engineered, or the cars will be pretty underivable over a typical race distance.

F1 YouTube channel has put a vid out covering the main details. Personally there's nothing so far I'm not in favour of, and that car looks amazing!

[Arklight]

I like that, but its all about the racing in the long run.

[Sammo123]

If the cars actually end up looking like that and do what we’re being told they can do then I’ll be happy

Looks promising!

With less over car aero parts, will we see much higher top speeds again?

The F1 bosses expect them to be around three seconds a lap slower than the current cars. Not sure about the top speed increasing but I'd doubt it.

The car looks good and it seems like we know finally have a sensible revenue distribution model. If the car delivers what it promises, then this really will be win-win-win.
