McLaren has become the latest team to release audio from the first fire-up of its 2016 Formula 1 engine.
The new Honda power unit was started up for the first time at the McLaren Technology Centre, with the MP4-31 roaring into life.
The 16-second clip was posted by McLaren on Twitter, following Ferrari’s engine fire-up video post earlier in the week.
The new McLaren will be unveiled on the 21 February, with an online launch one day prior to the first pre-season test.
The Woking-based outfit was one of the last to announce that its 2016 car had passed the mandatory FIA crash tests, confirming the news on Tuesday.
Winter running kicks off at the Circuit de Barcelona-Catalunya on the 22 February, with the four-day event being proceeded by the second test from the 1-4 March.
