What Pirelli say about this track and race:
2017 Qualifying
2017 Race
Fastest Race Lap: 1:35.378 (L44, L. Hamilton; Mercedes)
Pirelli have skipped a compound and are bringing the ultrasoft as the qualifying tyre, should mean this race could throw up a similar tyre strategy variation as the last race.
Whilst this track has a very long back straight (one of the longest in F1), the total % of full throttle per lap is lesser than Bahrain, fuel consumption is also lower. Downforce level is said to be medium, as despite having quite a few high/mid speed corners, the end of straight speed is still very important for defending from attacks.
The cars spend the vast majority of the long straight doing well over 250 km/h, so good aero efficiency is important for a good race car especially for those in the midfield. It’s a front-limited track in contrast to Bahrain as well, so the midfield order could well throw up another surprise. Who will get it right and who will struggle?
Looking at the tyre choices, the teams are definitely anticipating a 2-stop race.

The tyre choices:
What Pirelli say about this track and race:
- Turns 1 and 13 are the most demanding corners for tyres. Turn 1 is a decreasing radius corner leading straight into Turn 2, while the long Turn 13 is taken at high speed.
- There’s a very long straight that can have the effect of cooling the tyres, meaning that drivers need to pay attention to the braking area: this is also a key opportunity for overtaking.
- The circuit isn’t used much during the year, which can make it quite ‘green’ and slippery.
- The 2017 strategy was influenced by rain and safety cars. Lewis Hamilton won with a two-stopper, starting on the intermediate and then completing two stints on the soft.
- It’s quite a fast and flowing circuit, with lateral forces (cornering) more predominant than longitudinal forces (acceleration and braking).
- In cold weather, some graining has been observed in the past: especially in free practice.
- The surface is quite smooth, making it easier to find a consistent set up: the main challenge is to identify the best compromise between downforce and drag to find the right wing level.

Looking forward to this. What's the story with the number of pit stops shown for last year's race?

Seem to remember some good races here. I'm not a big fan of the track but I like turn 1 and there seems to be decent overtaking opportunities in a couple of places.

That's better. Glad my sanity is just about still in check, possibly.

Yeah, the track does see some good racing although some of the passes felt a bit inevitable in the narrow pre-2017 cars, I think last year the effect of DRS+slip streaming was spot on, so the passes were good...hope the same for this year. I only paid attention last year, but the turns 1 through to 4 was very interesting to observe, how different drivers approached it over a qualifying lap.Seem to remember some good races here.

Hang on medium, soft and ultra soft?? No supers?
Haven't noticed a selection like that before, they are usually three sequential compounds aren't they?
It's a new thing Pirelli are doing this year to have more of a spread in tyre performance to encourage strategy variation between drivers/teams.Haven't noticed a selection like that before, they are usually three sequential compounds aren't they?
Bridgestone used to do it too, bringing two tyre compounds to a race that are two steps apart.

Thanks Dr Z for an excellent opening post, as always.
I expect it'll be an interesting race.
My only real wish is that McLaren and Alonso maintain their championship positions. (Its a big ask!)

If williams can't get a point here thy are doomed for the season
Given the weaknesses of their car seem to be aero, handling and top speed I’d say they’re pretty fked everywhere but you need all of those things to work in China to do anything. Gassing Station | Formula 1 | Top of Page | What's New | My Stuff
