Sam Bird's Envision Virgin Racing team radio: "Ok, take a breath. I'll just remind you both of the Mahindra's are out, so this is a points haul, a points haul."
The translation of that team radio is: Don't do anything stupid because you could be leading the points by the end of the day!
Keith Massey: Getting into this electric motor racing. Great skill by the drivers on a tight circuit and love the siren sounds from the power chain. Incredible acceleration! Great coverage @BBCSport
Richard Hornby: If they all go to attack mode, Mortara is going to be a sitting duck.
Rob Spedding: Today’s @FIAFormulaE #HongKongePrix demonstrates every element of a top level international racing series. Great cars, same chassis, different surfaces and grip levels, varying conditions, attack mode and unforgiving walls to punish the slightest mistake. #FormulaE #BBCFormulaE

It's so slippery at that right hand turn at Hong Kong station.

Our pole sitter is out, as his car grinds to a halt.
Retired drivers:
Formula 1 fans will know it's advantageous to be leading since drivers have the clean air in front of them. In F1, drivers who are following in second they receive dirty air from the car in front which affects the amount downforce they have and causes their tyres to degrade quicker.
However, in Formula E, that scenario is flipped. The cars can race closer together, and since the cars are powered electronically, there isn't as much dirty air as there is from a fuel powered engine.
Formula E cars can draft one another (like in cycling) to save energy. On this occasion Lotterer is using more energy as the race leader, whereas Bird is following closely in second, saving some of his energy.
Smart racing from Sam Bird. He thought: "I'm not going to lose position and take myself out. I'll get to [Lotterer] later on."
Image source, BBC SportThe drivers are beginning to use their first lot of attack mode. Which gives them 25kw of extra energy to deploy.
However, you may notice Andre Lotterer's battery power is about 4% lower than Sam Bird's behind in second.

This is one of those points were if you're Andre Lotterer you want to push a little bit hard but if you're Sam Bird, you'll need to wait to see if they guy in front will make a mistake.
There's 25 minutes plus one lap to go.
Lotterer is our leader.

A problem for Sam Bird is he's got to push even harder to close that second gap of race leader Lotterer at the front.
If you've just tuned in, and you're new to Formula E, here's a quick explainer.

Oliver Rowland is very new to Formula E so he's probably going to be a little bit nervous but Sam Bird is an expert at applying consistent pressure.
Image source, BBC SportFormer One Direction singer Liam Payne says: "There's always so much drama.
"It's the first wet race they've had here and one team is already out, it's crazy.
I've actually got Stoffel Vandoorne trending fifth worldwide for the fanboost.
So hopefully that will help him out!

The Brit overtakes the Brit. Oliver Rowland's car grinds to a halt after the re-start, and Sam Bird takes the lead after starting in seventh.
Green flag! The cars meet the track again.

Mike Wood: Over 40 overtakes in first lap, probably the same in a whole season of formula 1. FormulaE was ok first year, but this year it's awesome, big thumbs up to BBC for the air time.
Red Firecracker: Did Nasr's front right suspension break on the curb turning into the corner?
Daniel Eckerlsy: It you’re new to FE and want to know if it’s always this mental...Yes. Yes it is
Julie King: Exciting Sunday morning ahead, kids and I all assembled on the sofa. @JamieChadwick55 doing amazing job in the studio, @Jack_Nicholls on top form and we have everything crossed for @svandoorne
Envision Virgin team Principal Sylvain Filippi, speaking on Sam Bird making up five places in that first section of the race, says: "It was an incredible start - we told him to take it easy at the start because the track is wet, and he didn't.
"At the beginning it's about space and if you're in the right place at the right time then it's a long way to go. A red flag at the beginning is annoying but that's what we have."
