The secrets of Honda's 'smaller than size zero' 2021 F1 engine

Honda infamously returned to F1 in 2015 with McLaren boasting about its 'size zero' packaging - a demand from the team that made the Japanese manufacturer's comeback much more difficult than it should have been. After those early failings Honda abandoned the idea with an engine revamp for 2017, but four years later it is now capable of producing an even tighter package than the one it failed to get results from with McLaren. Scott Mitchell explains how it achieved that, why it's a different attempt this time around, and what else we've uncovered about the engine that Honda is hoping will allow it to bow out of F1 in style in 2021.

    After seeing the Race at Imola which happened on 18th April I believe Honda has a 50-50 chance of winning the F1 title in 2021. But never rule out Mercedes and Hamilton especially, after he skidded off the track he dropped from 2nd to 8th but after daring skills and lots of DRS he quickly climbed back to 2nd but not close enough to trouble Verstappen in the Red Bull Honda.

    Why does “competitive season” have to equal rules changes to hurt Mercedes instead of the other manufacturers stepping up their game? Honda made great innovations but will we really see that they work since the rules were strictly written to punish not only Mercedes engine but also their chassis design? But yes let’s talk about someone finally giving it a go against Mercedes...leave the rules alone and then let them bring their best stuff and then if they challenge the mErc’s it would be legit. Even against all the odds the Mercedes still whooped the Honda’s. Lol

    "Size 0" during the McLaren period was pushed by McLaren, not Honda. Honda were against it because of heat dissipation issues. McLaren kept pushing and as a result got an engine which overheated rapidly, hence the drop in power and failures. Stop blaming Honda for McLaren's hubris.

    A lot of good this does when you GIVE the win to Mercedes! Max had Lewis' number at Bahrain but handed track position back to Lewis in a disgusting display of subservience and years of Stockholm syndrome. No way I would have given that position up. I would have let the Stewards make that decision all their own. Then they would look like jerks, because Lewis ran off track on lap 51 and gained advantage but not a word was said and he was not required to give up anything! LAME....

    How much longer will last in its present form ? The failure of leadership since 2011 has lead to a nose dive for this sport who has to compete with the finite sponsorship purse world wide. It been unable to attract two further teams on the grid due to capital barriers,media contract handcuffs for sponsors who have simply walked away from teram sponsorship to other sports. Whilst the smaller teams have been unable to compete as the sponsorship monies comming in have not been ditributed uniformly. We are comming to another crunch point when the combustion engine must be replaced by other technologies to meet climate change.The sport finds itself with no chair when the music stops. The latest vacum of leadership has let radical left wing political groups start the corrosive process of exclusion of sponsors, countries, and Brands from been associated with the sport. It is unclear whether Steffio Deminicarli apealsment stile will help this decline. Already he has taken his eye off the ball for the EU legal requirement to introduced quotas for all teams of 5% of severely disabled to be employed at senior level in all teams and suppliers this year and publish in the consolidated balance sheet on how this is going to be acheived in the next twelve months. The European/UK courts could fine promoters of the sport for not complying with this primary legislative requirement which could cancel some races in the European area. The retirement of Frank Williams and Robert Kubica with semmingly no replace of severely disabled replacement candidates has put on the red light to law enforcers and lobby groups. The courts have already warned that the sport must comply with disabled inclusion or risk procecution as they have had ten years to substantially change the sport to comply with the primary legislation. It is pointed out that the blind and severely disabled are the only legally recognised in primary legislation for quotas to be imposed on F1. This is distinct from political lobby groups or lower legislative boddies. How will Steffino and press license holders comply with this primary legislation in the next twelve months after ten years of inaction and deniel?

    I know pre-season testing means nothing but... in 2015 what we saw was what we got and pretty much has been since for most teams except Ferrari. Even when Merc hasn't been runaway favorites, they've been strong and RB has always seemed a step behind. Now they look a bit closer I do believe we will have a fight on our hands. Bring it on.

Stupidity spirit is good at many thing ! But adjusting the car is not one of them ! If hamilton and bottas need the car to go upside down on the track to go fast ? They have to word it to who ever they need to ! otherwise car stay down side down !
