If the Honda has a few more horses then Renault, then it would be all on this year. But new regs, its a reset and some will have got it right more than others, are 2 seconds a lap better, but after 5 years it will be closer, rinse and repeat
Its so annoying, after 5 years of these hybrids, last year was a 2 team championship, this year likely that RBR is closer, so a genuine 6 car title race (well, 3 car actually....)
I don't know why But I thought the new regs included engines, doh.
So, with that fumble out of the way, it might be darn good this year as the gaps will continue to close. Regs to tidy up a few things, remove aero help, which will help those with good balance and mechanical grip, i.e. RBR
