We've heard many times from McLaren about how big a job it is to integrate a different engine package into the chassis. Well, Toro Rosso is a much smaller team and has had the same task in the reverse direction by switching from Renault to Honda.
Toro Rosso has been unfortunate enough to have made such changes a lot recently, having used Renault engines in 2015, year-old Ferraris in '16, Renault again the year after and now Honda for '18! For a team with that manpower and budget, having to do that job does mean there's so much more that it can't get on and do.
But this is a tidy-looking car nonetheless. The car has joined the club of the current regulations by taking some of the best ideas from both Mercedes and Ferrari, who seemed destined to lead the way.
