McLaren will fit a new sensor to its Formula One car from the Malaysian Grand Prix, after revealing Fernando Alonso felt a sense of 'heavy' steering before his testing accident last month.
McLaren had blamed a strong gust of wind for the crash that ruled Alonso out of the first race of the season after he suffered concussion due to the heavy impact against the wall.
The team insists there is still no clear data that shows anything was wrong with the car, but revealed on Monday that Alonso has recalled something was not 100 percent right with the steering.
"While there was nothing evident in the extensive car telemetry data, nor anything abnormal in the subsequent reconstructions and laboratory tests, Fernando recalls a sense of 'heavy' steering prior to the accident," said McLaren in a statement.
"Consequently, the team has fitted an additional sensor to the car, to increase our data capture."
McLaren also confirmed Alonso will return to the cockpit in the Malaysian Grand Prix once he passes the final FIA medical assessment on Thursday.
"Since his Barcelona testing accident, Fernando has followed a rigorous, specialised training programme, designed and closely monitored by leading sports scientists, to ensure his safe and timely return to racing.
"At the McLaren Technology Centre last week, Fernando met with his engineers and drove the simulator, to bring him up to date with the latest developments on the MP4-30 chassis and power unit.
"As part of that process he spent time with senior engineers, discussing the accident and reviewing the comprehensive data and analysis, all of which has been shared with the FIA.
"Fernando is very much looking forward to getting back into the car and making a substantial contribution to our collective efforts with Honda, to accelerate the required improvement to our on-track performance."
