Aston Martin Red Bull Racing were forced to change their Honda engine during the second day of winter testing as a precaution. After checks, the engine has no problems and will be back in the car tomorrow.
Alexander Albon had his first go inside the new RB16 on Thursday after Max Verstappen completed both the first day of testing in Barcelona and the film day at Silverstone last week. Red Bull Racing head of engineering confirms there was a small issue.
"We had another very productive day with the RB16 today and although we didn't complete quite as many laps as yesterday, we once again got through all of the test items on the list," Guillaume Rocquelin said.
"We did have a small issue just before lunch when the Honda guys noticed something in the data and we, therefore, elected to perform a precautionary engine change. They've done a thorough check and there are no problems, so the original PU will be back in the car tomorrow."
