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.
"Although our renewed alliance began again many months ago, the launch of the McLaren-Honda MP4-30 marks the start of a lengthy journey," said chief executive Ron Dennis in a statement.
"I'm positive that, together, we'll get to where we want to be: winning Grands Prix and eventually World Championships as McLaren-Honda."
Flecks of red along the MP4-30's snout recall the red and white cars of McLaren's Honda-powered glory days in the late 1980s, when Alain Prost and Ayrton Senna dominated the sport.
Those days have seemed a distant memory over the past two seasons, during which time McLaren failed to register a single victory, but two-time champion Alonso said the team are ready to challenge for honours again.
