Can Mclaren win championships with Renault?

[zako85]

McLaren started its long decline in 2013, where during the transition from 2012 to 2013, it went from hero to zero (McLaren was arguably the dominant car at the end of the 2012 season). The 2012 car reached the end of its development potential they said, despite many calls to return the 2012 car in mid-2013 season, so bad the 2013 McLaren design was. Then in 2014, McLaren went down even more, scoring zero podiums despite using the dominant Mercedes engine. Mercedes stopped sharing information with them, they said. Then they moved onto the Honda engine and had three horrible seasons as the backmarkers and F1's laughing stock. They blamed it on the Honda engine and then passed it onto Toro Rosso (who are now a solid mid-field team). Now in 2018, they use the Renault engine and if it wasn't for Force India's transfer of ownership, McLaren still would have been only in the the seventh constructors place right now.

So what should we conclude? We have seen six years of failures for McLaren. Why would we expect better for them in 2018?

PS: sorry I meant 2019 there.
