Renault is having a difficult time with its latest contender, the R29. After suffering a lack of running due to bad weather in their first test, the current Jerez test is hardly better, as the car is running the least laps of all teams.
On top of that, the car is the slowest 2009 car so far. Rumours are that Piquet is already getting frustrated by the lack of running he has had with the car. He is however reported to be optimistic about the car's potential despite minor gremlins that currently prevent much running.
Instead of going to Barcelona next week, the team is planning on taking the time to prepare improvements to the car due to be ready for a later test, again at Jerez. One week after it is likely that the R29 will be tested again at Portimao to better understand the car ahead of the Australian season opener at Melbourne Park.
