The Senna name will be reunited with McLaren after the British marque announced Bruno Senna as a factory GT driver for 2015.
Senna, the nephew of Ayrton - who won his three F1 titles with the Woking squad - will be joining Rob Bell, Kevin Estre and Alvaro Parente in the McLaren GT line-up.
Former Formula One driver Bruno will race in 'selected events', but his main role will be the development of the 650S GT3 and 650S Sprint models.
"It is a great honour for me to be joining McLaren; a team my uncle enjoyed such huge success with, and one of the most famous names in motorsport," said Senna.
"It is a great honour for me to be joining McLaren; a team my uncle enjoyed such huge success with."
"2015 is a big year for the whole of McLaren, and it is an exciting time to be part of everything that is taking place.
"I am looking forward to working with the team at McLaren GT who I had a chance to get to know when I raced at the Spa 24 hour a couple of years ago, and I am really looking forward to getting behind the wheel of the new 650S.
"A lot of effort has gone into the development of the car since the 12C GT3, which I raced, and it made a big impression on its debut at the end of last season. It is shaping up to be a big year ahead."
Senna has spent the last two years competing in the World Endurance Championship, including the Le Mans 24 Hours, and is also racing in Formula E.
"Our factory drivers are some of the most accomplished and capable on the grid, and Bruno adds further strength to our team.
"At only 31, he has a huge amount of experience, having raced with success in all major international championships including Formula One, European Le Mans Series, World Endurance Championship and the Blancpain Endurance Series."
McLaren said further details of Senna's racing plans for 2015 will be announced in the coming weeks.
