London: McLaren unveiled their new car, the MP4-30, which will be piloted by former world champions Fernando Alonso and Jenson Button in 2015, in an online presentation on Thursday.

The British marque will be running Honda engines for the first time since 1992 and they hope that Alonso and Button will help them end two years in the Formula One wilderness. But despite resuming their partnership with Japanese engine manufacturer Honda, the new car retains the predominantly grey livery synonymous with the team's 20-year partnership with Mercedes.
