The 2017 Formula One season hasn't started off well for McLaren. During testing in Barcelona, the team went through no less than five different Honda-supplied power units, and had its car fail multiple times on track. It seems McLaren's engine situation is so bad, it's starting to shop around for a replacement.
Reports from and suggest that McLaren has reached out to Mercedes about possibly supplying engines to replace the unreliable Honda units. According to , Mercedes has one customer engine program slot left for the 2017 season that was set to go to the Manor F1 team before it was shuttered.
According to the BBC's sources, talks between the two constructors have been "brief and informal," meaning there might still be time for Honda to get its F1 act together.
Even when its cars were working, McLaren was the slowest team in testing, setting a fast time 2.7 seconds off the pace. So not only is Honda's engine unreliable, it seems to be underpowered as well. If things don't improve, we might be seeing McLaren-Mercedes cars on the grid very soon.
