Palmer: Lazy drivers will be tested in 2017
9 January 2017 – Jolyon Palmer reckons drivers who have not worked hard enough in the gym over the winter will be "found out" due to the anticipated physical challenges of this year's cars.
Formula 1 cars are set to be four to five seconds per lap faster in 2017, compared to last season's numbers, through overhauled aerodynamics and much wider Pirelli tyres.
"I can see it making a difference," Palmer said of the changes.
"It depends… we don't really know exactly the performance [of the cars for 2017]. We know what the numbers are, but we don't know yet what the tyres are going to do.
"If it is what we think, it will show – certainly early on – who has been in the gym and who hasn't. If people are not in the gym so much, then I think they will be found out."
Palmer says is difficult to tell whether the changes will be positive for Formula 1.
"I think the cars going quicker will generally be a bigger challenge, but there will be some corners that will be less of a challenge because they will be flat," he commented.
Pushed on whether that will be negative for racing, he added: "It depends, maybe you can stay flat through Eau Rouge, when you are following, and you can get a massive tow.
"Maybe the slipstream effect will be more without DRS – but we don't know.
"I think you can look back and see when cars had a lot of aero it was quite difficult to follow, thinking of 2007 and2008, but they didn't have DRS and they were still overtaking.
"Some of the slipstreams were massive, but at the moment we are not getting much, so I think it's a double effect – we'll only really know [at the first round] in Melbourne."
Renault will launch its 2017 challenger on February 21.
