With drivers limited by just three of every one of those power component components for this entire year, moving on to the second element so early in the effort will be far from ideal.
On the back of several MGUK issues encountered in testing, Sainz admitted in front of the Bahrain Grand Prix that the energy recovery system was the ‘weak spot ’ of his vehicle.
“Hopefully they [Renault] will be looking at it, and they have been considering it throughout those last few days,” said the Spaniard. “and so they’ve learned hopefully the reason for the difficulties.
“We have put some solutions in place with this particular race, and if they works or not we need to find out. But it is true we had a few failures throughout testing, so it is some thing that is really a weak point of the car.
While visibility dramas are nothing new to Renault, that has endured some challenging times throughout the turbo hybrid era, Sainz explained that a collapse early at the very first race was not upto standard even though performance had improved.
“The PU [power unit], it is a strong PU at a straight line,” he explained. “We have done our steps forward in the ideal direction, and absolutely I advised this, however lap 1-1 of race one [to retire] is good enough. ”
On the flip side, Sainz believed that speed trap data from the opening race of this effort had delivered any reassuring news about power earnings.
“It felt as though we are getting great power, especially in both conditions — both qualifying and race,” he explained. “Our top rates this past calendar year, we’re 10-12kpm/h down into every qualifying semester, and this past year we look like I presume just 2-3km/h down.
“it ’s thanks to down-force but also since the engine has significantly improved.
“Unfortunately on reliability, I don’t mind if the speed is still so good if we can’t proceed through lap 11 at the very first race of this season. So hopefully that may improve. ”
