Renault were the ones that pushed for the new engine regs and yet seem to have built a dog that by all accounts is running @ around 125bhp less than the Merc, Ferrari is also having issues and they are around 75bhp down.
But none of it matters as the rules will be bent and twisted to help Renault and Red Bull back to the front
In the interests of the sport if the Renault is crap they will have to make changes even after they were signed off and sealed early last week F1 cannot afford for them to walk away.
But Honda is back for 2015 and Cosworth are interested and with McLaren leaving Mercedes this year people are wondering will Red Bull make the switch to Mercedes for 2015 but I can think of reasons why that may never happen.
