Lotus has confirmed that it will stick with the Coanda-effect exhausts on Kimi Raikkonen's car for the remainder of the Korean Grand Prix weekend.
The team tested its new design during Friday free practice at Yeongam and, after detailed analysis of the data overnight, the team is confident enough to stick with it.
Technical director James Allison believes that the benefits of the new concept will increase over the forthcoming races, as the team understands them better.
"We are at the beginning of a relatively long road with them," he said. "It's not straightforward to make them work from the start, but the numbers we got are good so we are quite pleased."
Lotus only has enough parts to run on Raikkonen's car in Korea, but the plan is for the team to be able to run it on both cars from the next race in India.
