What is this mystery Formula car?

[Blackout]

I think it’s a modified version of the Renault R29 (2009 car). Yep, some front wings were that basic back then

Actually I think it may be even older. The nose looks a lot like the nose used on the r27 showcar.

And this one is harder to guess but It can't be an R27 car. It's a very strange frankenstein car with the R26 unique sidepods and a single keel (R26 had a V keel under the nose)... but the airbox intake looks very close to the R23 one and that car had a single keel too. So this might be an R23 chassis/monocoque with re-adapted R26 engine cover, R26 sidepods, a modified nose, etc.

The Lotus one is the same car but with "2009ised" bodywork https://upload.wikimedia.org/wikipedia/ ... 213%29.jpg

Mercedes star is at a loss to explain what's going wrong with his new F1 car, dubbed "a diva" due to its unpredictability.

I believe this is a R27. R27 and R29 are extremely similar and I thought this was a R29 at first (I have seen it). But I found the small hole (I think it's for the rope to uplift the car while rescuing) behind the head rest, R27's hole is in a quite front position while R28 and R29's are at far back, at the edge of engine cover. This pic is highly possible to be this car, it was for sale and the description said it used some R28 parts. You can clearly see the difference of positions of two car's hole.
More ridiculously, this car somehow got a Benetton's rear end (see the diamond shaped taillight) and wrapped in Honda livery. It even got a Benetton and Honda chassis number plaques... Later F1 Authentics acquired this car and sold it as a R29... Here's the Honda livery sale link.
