Formula 1 teams should waste no time in implementing changes to make cars more spectacular, claims former driver Derek Warwick.
AUTOSPORT revealed last month that teams are evaluating a host of ideas to improve the look of the cars - including the potential return of sparks, vapour trails and glowing brake discs.
Warwick, who as president of the BRDC that owns Silverstone has an interest in the appeal of cars, believes such changes are a no-brainer, which is why he thinks they should be brought in without the need for lengthy discussions.
"I think that F1 always has to be cutting edge, it has to be ahead of the technology," Warwick told AUTOSPORT.
"And that is what we have got at the moment.
"But do we need to continually look at the show? Absolutely. Because that is what turns on the punter.
"The fans need to come in here [to a race track] and get goose bumps as they arrive. Things like sparks and vapour trails are all part of the package.
"But we should not just be saying these things in public. It is the sort of thing we should be going to Spain and suddenly the fans sees sparks coming out of the cars.
"That is what should be happening - as that has more of an impact."
One potential change to F1 that Warwick is not in favour of though is active suspension, which is being considered for 2017 as part of a cost-cutting effort.
Warwick fears that the current cars are already too complicated in technology terms - and he thinks that doing anything even more extreme would not be right.
"Active, I think that would be a wrong move," he said. "These cars are too technical now, too difficult to put together.
"In Bahrain I spent a lot of time in all the garages and you see that you cannot put a finger through any of the packaging as everything is so tight now.
"We have already got very technical cars. Do we need active suspension? I really don't think so."
