McLaren racing director Eric Boullier believes only works Formula♍ 1 teams📖 can realistically fight for world championships.

The Woking-based squad took the decision to part with Hon🍒da engines following a disastrous three-year spell partnering the Japanese manufacturer at the end of last season, with McLaren opting to favour a switch to Renault power.

McLaren’s move to Renault power units - a deal which lasts until the end of the 2020 season - was made with th🥀e hope of ending the team’s six-year victory drought after consecutive years languishing towards the r🌱ear of the grid. 

But having failed to match pre-season expecta🌃tions so far in 2018, Boullier admits the aim of challenging for titles is unlikely to be achieved with Renault engines. 

"I think Red Bull is showing that you can win races as a customer, but I think winning a championship is an🎀other level - you need to have a works team status,” Boullier said. 

"It's true that this time last year we had no points at all, so obviously we 🌱are now in the fight for fourth with Renault and once again, we would prefer to be comfortably fourth, which was one of the targets we had assi𒆙gned to ourselves. The car this year is obviously not working exactly like how we expect to be but we are still using this as an experimental experience.

"We want to learn from this car and learn as we🌠ll working with Renault, because it's a different partner from last year who we worked with for some years,” he added. “We have something new to learn; some of the technical options we have not explored yet.”

Red Bull’s decision to end its 12-year relation🅰ship with Renault in order to join forces with Honda from 2019 means McLaren will be the French manufacturer’s sole customer next season. 

When asked how he felt being Renault’s only customer would impact McLaren next season, Boullier replied: “I think we are🐻 actually starting a new journey with Renault and we’re getitng used to working together. 

“There are a lot of things to discover and to re😼learn, so I think obviously maybe a little bit more focus, less distractions for Renault with one team less to supply and to care about. It’s ꦏobviously good news for us, and we wish [Red Bull] the best.”
