Renault risked a late introduction of their V8 engine; it never ran until the new chassis was ready. The team instead preferred to run with a detuned V10 engine in the 2005 chassis. Within the first few days of testing it was clear this risk paid off - the car has run reliably and fast throughout testing.
In recent weeks, new aero parts have been tested, including a new nose with a Midland-like wide flat tip and two different rear wing formats.
As well as the curved launch wing, one wing with a flatter middle section was tried, as well as a completely straight wing. This provides Renault with a range of different downforce\drag solutions, which could allow them to adapt at the first races.
