The Marina Bay Street Circuit began construction in 2007. It was designed by Hermann Tilke, modified by a company called KBR (they're not F1 experts) and first hosted the Singapore Grand Prix in 2008.
It's certainly not a track that will find its way into the hearts of millions, and there's little evidence it's particularly popular with the drivers. One of the few positives is that the race is held at night, which makes the place look rather beautiful.
Sadly, it also makes most of the corners look exactly the same.
A lap begins with a reasonable run down to Turns 1 and 2, a medium-speed left-right combination which leads into another, slightly tighter left (Turn 3).
Overtaking into the first corner isn't going to be easy unless one car comes out of the final turn very close behind another.
Turn 4 is one of those barely-there kinks, but Turn 5 is probably the most important corner on the circuit. A near-90 degree right, it leads onto the longest "straight" Singapore has to offer.
It's not a normal straight because it's split almost exactly in half by a right-hand kink (Turn 6), which is taken flat-out.
After the two halves of the straight comes Turn 7, a tight 90-degree left which is the primary overtaking spot on the circuit. That doesn't mean it's easy—Turn 6 has a tendency to disrupt moves into here—it's just not quite as hard to pass as it is elsewhere.
It's normal to run a little wide on the exit of Turn 7, which may be picked up on by commentators in light of the debate about doing this earlier in the season.
There's a short run down to Turn 8, which is a slightly less than 90-degree right. Turn 9 is a 90-degree left (you may have noticed Singapore has a lot of these).
Next up is a short straight, the cars reaching 160 mph before braking for the Singapore Sling—the most interesting corner we'll encounter this weekend.
Named after the cocktail, the Sling is an awkward, fiddly little left-right-left chicane which Lewis Hamilton once described as "ridiculous" and "pretty much the worst corner I've ever driven in Formula 1."
The kerbs are very tricky and with little room for error, it's likely we'll see at least a few drivers bounce painfully through here this weekend. One or two might end up in the wall on the exit, as Kimi Raikkonen did in 2008.
If that corner is successfully negotiated, next up is a slow right-left for Turns 11 and 12. The circuit is very narrow here, and it passes over the Anderson Bridge before Turn 13, which is a moderately tight, near-90-degree left.
A straight follows, directing the cars up Esplanade Drive. It's only a short straight before braking for Turn 14, which is on the same road junction as Turn 8. This one's another near-90-degree corner.
The next section almost seems like someone decided there weren't enough corners, but it keeps the drivers very busy. Turn 15 is a flat-out left kink just before braking for Turn 16, which is a medium-speed right leading into an almost identical left (Turn 17).
This is where Nelson Piquet Jr. intentionally crashed out in 2008, letting teammate Fernando Alonso take advantage of the safety car deployment to win from 15th on the grid.
Turn 18 is an interesting one, a tight 90-degree left before the track passes into a pseudo-tunnel below a grandstand. The end of the tunnel and Turn 19 (right-hand, near-90-degree) is only a few metres down the road.
Turns 20 and 21 are a slightly more open, reversed copy of 18 and 19—right-left instead of left-right. There's also a little bit more run-off here.
The cars then head down a short straight toward the fast left-handers of Turn 22 and 23. These two are the final (and probably the most fun to drive) corners of the lap, and they lead back onto the pit straight.
The start-finish line is only a short distance after the exit.
The pit-lane entry is on the inside of Turn 22, and the exit feeds into Turn 2.
