The McLaren MP4-29 is the last McLaren in an era powered by a Mercedes engine, a final iteration ahead of the team's partnership with Honda as of 2015. It's also the first turbo charged engine since McLaren became the last team to win a race with a turbo in the previous turbo era as Alain Prost triumphed at the Australian Grand Prix in 1988.

The car was officially launched on 24 January and than debuted on track on 29 January on the second day of testing at Circuito de Jerez, Spain. The team had failed to start the car the day before but as of its track debut then ran reliably an quick for the remainder of the Jerez test.

At the launch, McLaren claimed to have responded to the disappointment of its 2013 season by "pragmatically framing our approach to the technical challenge. The new MP4-29, revealed today, is a sensible and calculated response to the new regulations."

This pragmatic approach showed at the launch and at the first test, where it was clear the team went for a low nose without tricks to work around the regulations while also going for a very conventional, but possibly very efficient push rod front suspension. A technical analysis from the launch showed the car's potential of development, whereas at Jerez, the team immediately showed an innovative butterfly suspension.

Following reasonably promising running in pre season tests, the team immediately scored a double podium with Magnussen second and Button third following the disqualification Daniel Ricciardo at the Australian Grand Prix. After that however, things went downhill, with Button three times finishing fourth as the best results for the remainder of the season.

At the very end of the season, things started to progress as new Chief Engineer Peter Prodromou pushed ahead with a front wing design inspired by what he did at his former employer, 4 times World Champions Red Bull Racing. It essentially boosted the team for 2015, making Eric Boullier confident that his restructuring operations were starting to come to fruition.

McLaren ended the 2014 season with 181 points, good for a 5th place in the Constructors' Championship.
