Honda's new F1 engine to turn its first laps in a McLaren at a filming day at Silverstone McLaren will give Honda's new F1 engine its first laps at Silverstone. MCLAREN have confirmed that they will debut Honda's new engine during a filming day at Silverstone on Friday. The team will end their 20-year partnership with Mercedes at the end of the season to reunite with the Japanese manufacturer, with whom they four consecutive Constructors" Championships between 1988 and 1991. McLaren confirmed on social media they would run "the interim Honda-engined MP4-29H/1X1" at the Northamptonshire venue on Friday. The team have been working on a test car to house the new power unit, but its running will be limited to just 100km due to the Sporting Regulations. Neither race driver will take part with the driving shared between test drivers Oliver Turvey and Stoffel Vandoorne. The team will also run two classic McLaren Honda's at Silverstone alongside their interim car. The team has prepared the MP4-29H/1X1 in order to do a systems check ahead of the launch of the renewed partnership's first bespoke McLaren-Honda early next year. "To make sure that we are ready at the launch of the new cars in 2015 we've decided to build a development car, as Honda needs to check all the multiple systems," team boss Eric Boullier revealed last month. We also need to check the IT link between track and Woking and between track and Japan. So as not to have to focus on these things too much in the test season, we've decided to run a development car programme. Gerhard Berger won McLaren and Honda's last race together in 1992. The move comes as McLaren prepares to trial a major upgrade package at the season finale in Abu Dhabi next week. It's believed the significant upgrade, penned by McLaren's new chief engineer Peter Prodromou, has been shaped by the aerodynamic concept that next year's car will be designed around. "At the moment they're just going to test it on the Friday," Sky Sports F1"s Ted Kravitz reported. It's a completely different concept, pretty much next year's concept, which the wind tunnel (data) is already saying is going to be better than this year's car. They're not sure if they're going to race it, but they're certainly going to test it. McLaren's 2015 line-up remains the subject of speculation. Fernando Alonso is expected to join the team from Ferrari next season, and will partner either Kevin Magnussen or Jenson Button. The first photo of Honda's new F1 engine.
