November 16, 2009 – Mercedes announces that it has bought out the Brawn Formula 1 team, returning the manufacturer to works status for the first time since 1955. McLaren, powered by Mercedes since 1995, consequently loses priority, but the engine partnership is renewed through to 2015. “We’re delighted that Mercedes-Benz has committed to continue not only as an engine supplier but also as a partner of ours until 2015 – and perhaps thereafter,” says then boss Ron Dennis.
2010/11 – McLaren continues to fight at the sharp end of the Formula 1 grid while Mercedes holds fourth place, adrift of the leading teams. Mercedes, meanwhile, begins to concentrate the bulk of its attention on the new-for-2014 regulations, with the power units receiving their first test run on the dyno towards the end of 2011. At the same time, rumours persist that Honda will return to Formula 1 with McLaren, potentially as early as 2014.

December 11, 2014 – McLaren confirms that it has signed Fernando Alonso on a three-year deal to partner Jenson Button. “I am joining this project with enormous enthusiasm and determination, knowing that it may require some time to achieve the results we are aiming for, which is no problem for me,” explains Alonso.

February 22, 2015 – Fernando Alonso crashes heavily through Turn 3 at the Circuit de Barcelona-Catalunya and is hospitalised as a precaution, with the cause of the accident remaining a mystery. Alonso ultimately withdraws from the final test, and opening race in Australia, as technical problems persist, leaving the team firmly on the backfoot.
March 15, 2015 – The first race of the partnership is a troubled affair. McLaren qualifies as the slowest team while Kevin Magnussen is unable to even take the start after smoke trails from his engine on his reconnaissance lap. Jenson Button finishes as the final classified runner in 11th place, having been lapped twice by race winner Lewis Hamilton.
May 24, 2015 – After a string of difficult events, as it becomes clear that Honda lacks energy deployment at the end of straights, the partnership scores its first points in Monaco, as Button comes home in eighth place.

Mid-2015 – Honda insists the relationship with McLaren remains healthy, and continues to target podium finishes across the remainder of the year, despite engine penalties racking up.

November 14, 2015 – Alonso, having humiliated Honda at Suzuka by labelling his power unit a “GP2 engine”, stops on track during qualifying at Interlagos. Alonso slumps trackside in a deckchair and briefly sunbathes, before he and Button make their way to the podium, demonstrating some black humour.

Mid-2016 – Honda remains the weakest power unit but gains enable McLaren to fight in the midfield, regularly finishing in the points, as reliability also improves. Boullier labels the transformation from 2015 to 2016 as “day and night”, and tells GPUpdate.net: “Based on where they are today and what we expect them to step up, we will get there. We will get there. I don’t know if it will be in six months, one year or two years. But we will get there.” Boullier also hints that the new 2017 regulations can be seen as a reset for everyone – including McLaren.

But I’d like to think we can target the second half of the year as a time when we’ll really be able to start making useful performance steps.”
March 8, 2017 – Pre-season testing turns out to be an abysmal period for the partnership, amid an absence of reliability and performance at the Circuit de Barcelona-Catalunya. Alonso comments: “We have only one problem at the moment and that is the power unit; there is no reliability and there is no power… I think we are around 30 km/h down on the straight, every straight.” Boullier admits the partnership is at “maximum strain”. Hasegawa concedes Honda is slightly “scared” about its performance deficit.

June 7, 2017 – Brown comments that McLaren has “serious concerns” over Honda, believing the engine supplier to be “a bit lost”. “Our preference is to win the World Championship with Honda,” he says. “But at some point you need to make a decision as to whether that’s achievable. And we have serious concerns. Missing upgrades, and upgrades not delivering to the level we were told they were going to, you can only take that so long. And we’re near our limit.”
June 8, 2017 – As doubts swirl over Alonso’s future, he makes an emphatic statement in Canada, declaring: “If we are winning before September or something like that, [when] I will make a decision, then I will stay.” Clearly, it is noted by observers, McLaren will not be winning by September…

We have some plans.” Hasegawa responds, stressing: “It is very unfortunate that we can’t give them a good [power unit], we can’t convince them that we can do that. Of course, we need much improvement from the performance and reliability point of view – we will do everything and we need to do everything.”

June 20, 2017 – Mercedes boss Toto Wolff insists the manufacturer will “not interfere” in the McLaren/Honda saga. “This is not our priority at the moment,” he tells GPUpdate.net. “First, we would like to see Honda and McLaren sorting out their relationship.

July 7, 2017 – After an evaluation during practice in Azerbaijan, and Alonso scoring the team’s first 2017 points in an attrition-filled race, Honda brings its Spec 3 power unit to Austria. Only Vandoorne runs it in the race after Alonso suffers reliability problems following Friday practice.
