McLaren's Formula 1 executives are clearly feeling pleased with themselves as the 2017 season reaches its denouement. Zak Brown says the team is almost having "a few giggles", such is the level of excitement building within Woking at McLaren's F1 prospects for '18.
The MCL32 is clearly a good F1 car, it has developed strongly, and those woeful Honda engines are about to be consigned to the dustbin of recent history. A new deal with Renault is struck, which means dollops more power to go with a car McLaren's data suggests is broadly a match for the Red Bull RB13, which has won three races against the might of Mercedes and Ferrari this year.
That's a job well done for McLaren's senior management - a good reason to pop the champagne corks, and who doesn't get a bit giggly after a few glasses of champagne?
