Raikkonen, Hulkenberg, Verstappen and Wehrlein set their best times on the ultra-soft tyre; Alonso on the super-soft; Massa, Nasr, Kvyat and Palmer on the soft and the rest on the medium
So with that, the penultimate day of testing is done, with Kimi Raikkonen finishing with the fastest time of the day.
A red flag brought the morning session to a close early and the same has happened with the afternoon session.
And it looks like it might be Romain Grosjean again...
A first for Fernando Alonso in pre-season testing, he's got the ultra soft tyres on his McLaren...
F1 journalist Dan Knutson in Barcelona: "Today is the last time that Kimi Raikkonen, Daniil Kvyat, Nico Hulkenberg, Max Verstappen, Felipe Nasr and Fernando Alonso will drive their cars until the opening day of practice in Melbourne on 18 March.
"Valtteri Bottas and Kevin Magnussen had their last day yesterday.
"Romain Grosjean is scheduled to drive the Haas tomorrow, but the team is still deciding if Esteban Gutierrez will get some more time in the car on the final day of testing."
Pascal Wehrlein, there's a name we haven't mentioned for a while.
After two hours in the garage he is back out, ultra soft tyres on his Manor, and he clocks 1:24.913. A marginal improvement on his previous best.
F1 journalist Dan Knutson in Barcelona: "The Pirelli tyre fitters have been kept busy throughout the test."
The tweet below was the update at just before 16:00 GMT and the good news is that they've managed to get the Haas fixed up and ready to go again, so out goes Romain Grosjean for the final 40 minutes.
Felipe Nasr brings his race simulation to a close with 107 laps to his name. Looks in good shape, my legs are still shaking after 17 laps of go-karting.
