World champion Lewis Hamilton coasted to victory from pole position at the year-ending Abu Dhabi Grand Prix on Sunday, and in doing so equaled his personal best for a season with his 11th win of the campaign.
He met ex-Formula One boss Bernie Ecclestone as well as a number of race fans and businessmen.
The Mercedes team chief, who has overseen Lewis Hamilton's memorable fifth title triumph and the Silver Arrows' fifth consecutive constructors' championship, said he felt humbled by the celebrations last week, but also determined to continue setting the pace.
The former McLaren driver has now won four races in Abu Dhabi to move ahead of Vettel's three.
"Since Monaco I've been hoping for a strong weekend and now this is my last chance with the team".
Red Bull's Max Verstappen, fastest in the first session with a lap of 1:38.491, was second fastest in the evening and 0.044 slower than the Finn.
"I saw a little bit of sky, tarmac, sky, tarmac and ended up upside down!" We've been talking about it for so long. I was racing Romain into Turn 8 and we both locked up. "I have no doubt we have the right people in place to take a step forward in 2019".
Williams engineer Rob Smedley foresees better racing, but issued a warning that it will not solve every problem that Formula One has.
Still, he's a hugely respected driver - arguably one of the greats.
It was a moment that left onlookers with their hearts in their mouths - but Nico Hulkenberg has played down his spectacular opening lap barrel roll in Abu Dhabi as "nothing really dramatic".
And Vettel, whose season was punctuated by a series of costly errors, admitted: "I think I need some time for myself".
When asked if Alonso could test the 2019 vehicle, Brown said: "Yeah, I wouldn't rule that out".
"Now, with age and experience, I'm able to do that".
"It is still the only team that I have worked with in formula one", said Vandoorne, whose did not flourish in F1 despite his ultra-promising junior career.
"But I do believe there's always areas to improve so we'll definitely look at the season, at the end of this year, and there'll always be areas you look at".
