Power unit supplier Renault has warned that its fixes for this weekend's Bahrain Grand Prix are merely temporary as it attempts to recover from a difficult start to 2015.
Both Daniil Kvyat and Max Verstappen retired from the Chinese Grand Prix due to Internal Combustion Engine (ICE) failures, adding more pressure to Renault after problems in the first two races.
But the short turn around time between races in China and Bahrain means that the French company has only been able to apply temporary solutions ahead of this weekend's round in the desert.
"The Bahrain International Circuit is relatively similar to Shanghai with extended periods of wide open throttle and long straights," said Director of Operations Remi Taffin.
"We go there knowing it may not play to our strengths, but there are still opportunities to take the fight to the front of the field. Our Power Unit has moved forward in driveability and although there is still some room to play with, this should pay off in the twisty back section and under braking at the end of the straights.
"As well as optimizing performance, a significant part of our preparations for this race have been and continues to be analysing the issues from China.
"As a consequence, we will have to make some late calls. We now know that the failures on Kvyat and Verstappen’s ICEs are different and unfortunately one of them was known but built in when then ICE was introduced early on. The other is still to be fully explained and temporary fixes will be used in Sakhir."
