M-Sport drivers Sebastien Ogier and Elfyn Evans have done back-to-back tests with a new rear aero package on their 2018 Ford Fiesta WRC, ahead of the upcoming Rally Finland.
The current-specification car has taken three WRC wins so far this season in the hands of Ogier, but with title rival and points leader Thierry Neuville having won the last two rounds in Portugal and Italy, M-Sport is keen to achieve a performance boost for the six remaining events.
Team engineers have been busy in recent weeks developing new aero components for the rear of the Fiesta to improve stability and grip. The main focus of their efforts has been on the car's rear wing.
"We've got some parts coming for Finland and obviously we hope they're going to be an improvement," team boss Malcolm Wilson told Autosport magazine.
"The work on the rear wing was done in the wind tunnel in Charlotte (USA) when the car was out there [after Rally Mexico], the guys have been working hard on it since then.
A decision on whether the new aero package will be used in Finland will be made in the coming days.
