Since taking over the team from the previous owner, Renault has been spending its time and money restructuring its chassis base in Enstone. But you can only use that excuse for so long, and 2018 is the year that it needs to start producing results.
With Red Bull and McLaren now also using its power unit, there are very few places for Renault to hide. That is the same for Red Bull and McLaren, so it will be good to see this three-team battle. I don't expect Renault to do the same as Mercedes does when you compare it to its customer teams, but respectability will be nipping at Red Bull and McLaren's heels.
With Nico Hulkenberg and Carlos Sainz Jr on board, Renault has the drivers to achieve success, but they need the chassis and power unit to achieve that success. Renault has struggled since the new engine regulations were introduced in 2014 and going to a maximum of three units per season is not going to make the job any easier.
