McLaren executive director Zak Brown insists the team is "very committed" to engine partner Honda and that there has been "no conversation" about a future split.
Honda's disastrous start to pre-season testing prompted McLaren to approach former engine supplier Mercedes about possibly rekindling its partnership in future in case the situation does not improve. With a revamped V6 power unit and the removal of the restrictive token engine development system many had expected to see Honda back at the front end of the grid in 2017.
Instead, Fernando Alonso said the team is last in terms of performance after the Australian Grand Prix, but Brown says McLaren is determined to work through the current problems with its current engine supplier.
