Renault has made progress with their power unit ahead of this weekend's Chinese Grand Prix, according to head of track operations Remi Taffin.

Renault has been on the back foot for much of the season but Taffin believes that their four customer teams have received an improvement in grip and traction, especially at low speed.

"The cold temperature has made things a bit more interesting," said Taffin. "Even though lower temps do not change engine settings and fuel consumption this year, unlike with the V8s, it does make the cars move around a lot more, particularly with the harder tyre compound. As a result we have to make minor adjustments to give more traction, but with enough flexibility to adapt to the evolving conditions.

"The progress made back in the dynos at Viry, which was then corroborated on track at the test in Bahrain, has proved to be very useful and we appear to have consolidated our findings here today, allowing the teams to fully focus on their own run plans.

"Thanks to the software upgrades and some performance items, on a power sensitive track we are losing a lot less to the fastest cars. While it’s still a way off it does show we are going in the right direction. Likewise, the improvements in energy management and energy recovery have been well applied here and we’ve noticed an improvement in traction and grip, particularly in the slow corners such as T1 and the hairpins.

"Overall it’s been a productive day that has confirmed some steps forward. There are obviously still some more to come but from the longer runs conducted today we expect to be closer in race trim, which is what counts for points after all."
