McLaren/Honda's pre-season testing has been a disaster completing very few laps and failing to complete a simulated race distance.
It is believed that the power plant, it's not just a petrol engine these days but a complex hybrid, was running on reduced power yet the majority of the problems were power plant related.
Practice for the first GP of the season today, the Oz GP, was another problem day.
So it's not looking good for McLaren/Honda.
