Alonso's stint has been a bit erratic. His last time a 1:46.233. Three laps ago he posted a 1:44.786, so clear that these soft tyres drop off quite quickly. Suggests more than one stop on Sunday.
@ALessandro17: I think so - the drivers all say it's a circuit where you can follow much more easily than some other tracks. I would say we could have some really great racing on our hands on Sunday.
We're into the final eight minutes of this session now.
@Fényország: Forecast is for it to stay sunny all weekend.
(Back to the age discussion)
There was also a comment from someone saying they were 73, but I accidently deleted the comment rather than approve it. Wide age range of fans, clearly older fans not being put off too much by modern tech-heavy era...
Worth noting on Hamilton, he may not be using his race engine or gearbox so might not be an issue which carries over to tomorrow. But then I've been wrong before, once or twice.
@Phil,Maidenhead: Which grand prix was that Phil? And who was your favourite of all time?
@Mary-Paule: It would be in order of which one took the penalty - so if Hamilton took a penalty, and then Rosberg did afterwards, Hamilton would start ahead of Rosberg. They'd both be behind Vettel for the same reason.
I used to cover Superbikes in my previous job and I absolutely love Brands Hatch. Super, super circuit.
We're into the final minute of this session, but please do keep your comments coming in.
Rosberg labouring past Bottas on the straight, demonstrating how much the teams are struggling with the tail wind.
The clock has expired, that's the end of this session. We are due to have another trial of the 'virtual safety car' we saw at the end of the morning session. This is an initiative brought in after Bianchi's accident at Suzuka, to limit the drivers to a certain speed delta.
So, once again Hamilton tops a free practice session (his 14th one of the season), only just 0.003s ahead of Rosberg. Alonso is the best of the rest, a massive 1.104s down on his old McLaren team-mate.
The virtual safety car has been deployed - meaning all cars are driving to a certain delta. This idea is to neutralise the race and take the choice of speed out of drivers hands rather than judging it by themselves under double-waved yellows.
Thanks as always for joining me for this session, a pleasure as always - thanks to everyone who commented. Please be sure to join me again tomorrow for the one-hour FP3 - the last chance for these cars to get running in before qualifying on Saturday afternoon.
