Sauber is probably the team that has the most to gain from Formula 1's regulation changes for 2017. Over the past couple of years, it has struggled for budget, which has led to a lack of developments and a lot of time spent at the rear of the field.
It was only the wet race at Interlagos that brought Sauber its vital first points finish of last year, which allowed it to move ahead of Manor into 10th in the constructors' championship. That also brought with it a decently-sized cheque, which could be put together with the investment from new ownership to employ some much-needed, more experienced design staff.
After seeing the early renderings of the new Williams last week, I was a bit worried that the 2017 cars would mostly be a cut-and-paste exercise based on the previous models. But Sauber seems to have found some extra areas to optimise.
