Short answer: no. Long answer: noooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo
I'm pretty sure just building and designing a new engine is against the rules, but even if it wasn't, there's no point because there's only so much you can do without actual field testing. The only real way Honda and Renault can catch up is if the restrictions are lifted, because as it is they can only keep up with Mercedes at best.
Thanks, I thought as much. So under the current rules the haves will always be ahead of the have-nots.
It is one of those things where the engine itself is not so much the cause of Honda's woes as the inefficiency of their energy recovery systems, particularly the thermal energy recovery system.
It is thought that Honda effectively made the same mistake as Ferrari did in 2014 by focussing more on the compactness of their engine package - driven by McLaren's focus on having the most compact rear bodywork possible - in order to optimise the performance of the chassis, and in the process hampered the efficiency of the engine package.
In both instances, one factor that has been cited is the design of the turbocharger - in the case of Ferrari, it is thought that they underestimated the potential for generating energy from the thermal energy recovery systems and focussed more on responsiveness, driving them towards a smaller turbine.
In the case of Honda, it seems that the driving motivation there was to adopt the most compact unit possible to satisfy McLaren's packaging requirements. The suggestion is that Honda tried to compensate for the restrictions on the size of their engine package by using a more compact turbocharger that was able to hit the limit of 125,000rpm dictated in the regulations (the rumour is that Mercedes focussed on a larger unit that reaches 100,00rpm by comparison) to try and hit their targets for the energy recovery systems.
However, the talk is that Honda have found it much more difficult to hit that target speed than they first thought and, due to issues with the bearings, are currently limited to 100,000rpm, creating their current issues where the thermal energy recovery systems are performance limited.
Now, the progress of the engine manufacturers under the regulations has been somewhat mixed - Renault have definitely struggled, but on the other hand the rather fractious relationship between themselves and Red Bull has been something of a hindrance (for example, Renault being forced to fast-track development parts without adequate testing after being pressurised by Red Bull to speed up development work). On the other hand, the Ferrari powertrain has definitely improved significantly from 2014 to 2015, and their performance was not that much better than Renault in 2014.
