Barcelona, Spain - Carrying different goals for the 2016 Formula 1 season, Mercedes and McLaren unveiled their new cars on Sunday (February 21).
Mercedes hopes to improve on the few weaknesses of last year's Silver Arrows, while McLaren brings what it calls a "significant number of innovations" to try to get back to the front of the grid after dismal results in 2015.
New cars unveiled on teams' websites
Mercedes was clearly ahead of other teams in the last two seasons, easily winning the drivers' and constructors' titles. McLaren is coming off a nightmare 2015 under a renewed partnership with engine supplier Honda, finishing second-to-last in the constructors' championship.
The new cars were introduced on the teams' websites a day before the first session of preseason testing begins in Barcelona.
