Going into the off-season, Williams knew that their 2016 race car had to address the FW37's main weakness: low-speed cornering.
The FW38 looks quite similar to last year's FW37 race car, with a couple of subtle differences here and there such as the nose and the more aggressive rear.
The livery is also seems pretty much identical to what they were using in 2015, but in spite all this it is actually a brand new car.
According to team principal Claire Williams, however, it still needs development before it hits the track in anger.
"We are already planning updates for Melbourne and will be pushing for constant improvements over the course of the season", said Williams, adding that her team is entering 2016 "in a strong place".
Be that as it may, 2016 should be a more competitive year in Formula 1. It remains to be seen if Mercedes will still have an advantage over the rest or if Ferrari will have caught up, but it's more about the middle of the pack where teams such as Toro Rosso expect gain about a second thanks to its new Ferrari power unit.
Bottom line, it won't be easy for the FW38 to secure third place in the Constructors' championship once again, but the team will certainly give it their all.
Either way, we'll get a better look at the FW38 once pre-season testing starts on Monday in Barcelona.
