Renault has confirmed that its 2014 power unit ran in an updated configuration “without any reliability problems” during the Lotus filming days.
Lotus was present at Jerez over the weekend and managed to complete the maximum 100km of running allowed on Saturday with its new E22. Renault had been working on fixes for a number of problems experienced with its new power unit at the first test a week earlier, and Renault Sport F1 confirmed that it was able to authenticate those over the weekend.
“Basic objectives were to support the Lotus program with a power unit configuration and operation to allow systems' checks and basic car operation,” Renault confirmed. “The latest PU configuration was deployed without any reliability problems, allowing Lotus to complete the maximum amount of km permitted on a filming day.
”Updates developed in the dyno at Viry during and post-Jerez test were run. Updates included minor hardware changes, software bug fixes and calibration improvements,” while Renault added that “preparations at the factory are ongoing for the two Bahrain tests.”
Renault was also keen to point out that the filming day itself was not used to further develop the power unit.
”We should point out that no development was pursued during the filming day as stipulated in the sporting regs, rather upgrades trialled in the dyno in Viry were validated. As usual, everyone is committed to providing performance and reliability required for normal PU operation and a fully competitive 2014 season.”
