Ross Brawn, Formula 1's newly-appointed managing director of motorsport, has said he would like to see the shark fins and T-wings addressed in the regulations, as he feels they "spoil" the look of the 2017 cars.
Shark fins have made a return this season due to the lower rear-wings, whilst T-wings have sprouted at the rear of the car thanks to an opening in the regulations and a need to condition airflow running over the rear-wing.
Brawn, although happy with the overall look of the new cars, believes these two appendages must be addressed as soon as possible, though admitted it's common for unusual items to pop up with major regulation changes.
"As a racing car, it looks more exciting. The proportions of the car are better," he told the official Formula 1 website. "They’re much faster; pretty impressive performance. Drivers tell me they are physically challenging, which is what was wanted.
"As always with new regulations, there are few little hiccups. We’ve got the unpopular shark’s fin on the back. In time, I think we need to address those.
"Part of the objective of the new rules was to produce more exciting-looking cars, so we don’t want to spoil it with peripheral bits that take away from that. But that’s normal with new regs."
When asked about the T-wings, he added: "Those are all the consequences of new regulations, and not intended. So unintended consequences, over time, we need to iron out. And get the things looking a bit more pure."
The Briton is also keen to see the removal of DRS, but says that can only happen when the problem of overtaking is solved.
"We have to look at the whole topic of overtaking in racing, and how the cars can follow and overtake each other," he explained. "I would prefer that to be achieved by a normal process, rather than enhanced by something like DRS.
"But DRS was a solution to a problem we had at the time. I don’t think we should rush into taking DRS off, but what I’d like to see is a better long-term solution to car design so we don’t need it."
