Voilà ce que pense F1technical :
The car itself is clearly an evolution of last year's Renault R29 as it still features a big and wide nose cone that aims to create a low pressure area under it. The much discussed nose is however still under development and may see another development before the start of the season.
Just like in 2009, the front wing is again a fairly simple solution. It is actually a surprise to see this largely unchanged wing as Renault pointed it out as one of the reason that its car in 2009 was not good enough to be a front runner. I will not be surprised if the team is hiding a newer version behind the scenes.
The sidepods are also a clear evolution, and contrary to the three other cars that have been launched, the Renault has sidepod air intakes that extend to the car's floor, instead of featuring rectangular inlets high above the car's floor.
The rear end of the car is still very much unclear as most of the tail is covered up. The rear wing does however still sport a single central support, with heat stickers attached to them. The team will no doubt be interested in the temperature of this element when the car is driving, as the engine's exhaust have been moved backwards and more to the centre of the car.
Le museau n'est pas le bon,
L'aileron est un faux pour la présentation
Les échappements sont plus à l'arrière et cachés,
Le diffuseur caché comme tout le monde
