A simmering Jerome D'Ambrosio, speaking to Nicki Shields in the garage, he says: "Well it's ridiculous. You have a guy like (Felipe) Nasr causing a huge amount of smoke who caused a collision, he should have pitted to make it safe, and it should be a grid penalty for the next race.

"It's disappointing, we knew there would be an incident, but it's poor standards from him and his team not to pit.

Speaking on his championship lead, he says: "It doesn't matter at this stage we can focus on the next race."

This is a similar situation to what we had in Mexico when Nissan miscalculated how fast the leaders would be going and how many laps the race would be and they ran out of energy before then.

Today is going to be an even more complicated set of sums because as the track dries out it's going to keep getting faster and faster, so it's not going to be much of a static lap time.

Both of our challenging drivers are out. Pascal Wehrlein led the race in Mexico, and D'Ambrosio won in Marrakesh.

D'Ambrosio is our championship leader, and that's the end of the Hong Kong ePrix for him.

Wehrlein is also out of the race for the second time this year.

You can see different parts of the track is drying up, at Turns 7,8,9 and 10 but other parts still look pretty damp.

Sam Bird goes up to second, from seventh including a wheel to wheel with Stoffel Vandoorne.

As part of strategy, there's attack mode. The drivers can leave the racing line and follow some arrows on the track which gives them 25kw of extra energy to deploy throughout the race. All the drivers must use attack mode before the end of the race.

Oliver Rowland takes the lead, and comes out of the first hairpin ahead of pole sitter Vandoorne.

There's 10 turns on this street circuit in Hong Kong. And it's tricky for numerous reasons. The skyscrapers have caused problems over the radio in previous years when teams have struggled to communicate with their drivers. It may seem like a minor thing, but if you're the driver in the cockpit receiving no information from your team on what's happening around you, you have to make those strategic decisions yourself.

The cars are on the grid, the rain has stopped in Hong Kong and the track is drying out. Are you ready?

Rob Frost: Quality @FIAFormulaE coverage from the BBC. Combine this with the high quality racing and madness that goes with it and you've got a recipe for big success.

Nick: I'm up early in a Sunday??? It must be motor racing. So good to have racing back on the BBC. It's not just a warm up for F1

Lee: Up bright and early to watch #FormulaE, external and the #HongKongEPrix, external and possibly the first ever wet race! This could be more crazy than usual

Darren: Great to see Formula E back on the BBC this morning long may it continue

David Cunliffe: Scepticism parked. Giving it a try... After 40+ years of F1, now disenfranchised by Ecclestone’s Sky deal, I hope to be convinced. Excuse a newbie’s questions - are Tesla involved? If not, why not?

This is what we like to hear! Given the action from the first four races, it won't let you down. No Tesla aren't involved.

The track is drying out, since we had a very wet qualifying session earlier this morning when the Belgian Stoffel Vandoorne drove a stunning lap 0.5 seconds quicker.

But we are due to start in a few minutes time, so it may still be slippery conditions...

Stoffel Vandoorne for HWA Racelab, who starts on pole says: "It's great to be on pole today for the 50th E-Prix race.

"It'll be tricky conditions out there, as it was qualifying, so to do have done the job, especially when it's so challenging, was great.

It's important to start ahead but let's see if we can keep it up in the race."

Matt Cleevely: The BBC 2 continuity guy just announced ‘Rev your engines for the formula E’.

Jack Mannion: Lets see what all the fuss is about

Neil Denham: Coffee made, ready for a morning of electric action!

Skip: Good to be able to watch the 50th Formula E race on the BBC, would love to see them show more on the main channels rather than hide it on the red button

Really do expect the unexpected.

As Jamie said, it's got great drivers and great cars, with the biggest difference between this and Formula 1 - there's no engine, no fuel tank.

It's all about electric racing and that's at the heart of it. It's going to be spectacular.

We spoke to Sam Bird earlier this week about his helmet. He's got all the tracks on his lid.

Here's a breakdown...

Formula E is so exciting at the moment, it's taken the sport to a new level.

For me, the main thing is it's world class drivers and world class teams, going to some awesome venues, with the racing so close.

You really do have your heart in your mouth at the times and it really is that close, so I'm looking forward to seeing how this one pans out.
