14:26 That's all for now, folks. Thanks for joining us. We'll have more from the McLaren launch throughout the day.

14:20 Brown returns to the stage to toast the season along with Boullier and Hasegawa and bring an end to the seventh F1 launch of 2017.

14:19 "The track will be the proof," says Boullier. "We would like to see some progress. What I can say is that we will win again."

14:19 Boullier says he is "pretty happy" with the approach the team has taken. He adds that the relationship with Honda is "going very well". He adds: "They changed the layout of the engine this year, so we had to take this into account when designing the car".

14:17 "We are not making any promises for this season, but our aim is to make progress and catch up the frontrunners," says Hasegawa, echoing Alonso's stance.

14:17 "We have modified our engine, with a lower centre of gravity and lighter weight," says Hasegawa. "I'm very proud our team members have made a very good job for this season."

14:16 Honda chief Yusuke Hasegawa and McLaren racing director Eric Boullier have replaced the drivers on stage.

14:15 "It's an important season for us," says Alonso. "It's been a difficult 2015 and 2016 so we have high hopes McLaren will get back towards where it belongs. It's a complex sport, we need to not promise anything to the fans. We need to work hard, a lot of mileage in testing and have a clear direction for the next couple of months. If we are here today, it's because we believe we can win."

14:14 Vandoorne says from his experience in the simulator, the cars definitely feel faster. "If we look at the cornering speeds, they are a lot higher than last year so it will be a step up, but we've had a long winter of training so we're prepared."

14:13 Vandoorne believes the focus for McLaren is to work together as a team and make sure the team keeps making progress and helps the package get back to winning ways.

14:12 "It's a very exciting time for me, to be finally a full-time McLaren racing driver," says Vandoorne.

14:11 "They become sexy when they become fast, so let's wait and see," says Alonso.

14:10 "It's the first time we've seen it today," says Alonso. "I'm excited. It's nice to see some McLaren colours, some orange."

14:10 Stoffel Vandoorne and Fernando Alonso are welcomed onto the stage, donning white racesuits with an orange and black stripe.

14:09 "I'm a McLaren fan," says Brown. "We're going to get there. We have a new package and it's going to take time. Last year was forward progress and that's what we've got to see this year. I have no doubt with the driver line-up we have, I wouldn't want a different line-up, we have everything we need."
