I made this simple engine comparison last year after the US GP qualifying. It seems clear honda and renault were neck and neck in quali trim, with ferrari in a completely different league. Hard to see either of them could bridge this massive gap in one winter, even to only 3% as was mentioned. Until there's actual on track proof of performance I'll remain sceptical.
Quali graph from suzuka (open in new tab)
Here data would suggest renault was tiny bit ahead of honda a this particular track.
Hmpfff, the data is a bit skewed because the mclaren car is labelled, by the team's own admission, to have poor downforce and poor straightline speed. This is quite reflected in the graph too, with the mclaren consistently having to shave off more speed than toro rosso and mercedes, which indicates less downforce, so also lower exit speed the mclaren constantly has to compensate for.

and again you can't compare the Honda of last year to Renault or Ferrari, due to the fact that TR didn't develop there car (at least not as intensiv as Renault or Ferrari did) .....
Actually, you can as long as you take quite a few nuances in check. The youtube video is quite handy to check out the acceleration at every stage. Especially early acceleration out of the slower corner, when downforce and drag don't play as much a role, can tell a few things. The US comparison is not completely fully alligned, so I think any percepted difference between renault and toro rosso would fall into an error margin. Even with that regard, we can clearly say Ferrari was a lot better and on that strip the toro rosso and renault had roughly the same engine power/drag ratio.
The few things I take out of it concerning renault and toro rosso:
-Both have similar speed for the first stages of acceleration, indicating similar torque in said stage (when aerodynamics are a bit less of a factor).
-Both have similar acceleration and top speed across the whole straight, indicating the same power/drag ratio at the end of the straight. But, given the high amount of similarity between the speed continually across the straight, and also because drag increases exponentially with speed (and there if both cars have a different drag profile this would show during the acceleration period), we can say the drag level increased similarily with speed with both cars, so I think it's also safe to say both have a similar drag. Note that I can't say anything about the downforce level based on this data.
