Jenson Button called on the FIA to shorten the length of the Singapore Grand Prix, arguing that the event is currently too demanding for drivers.
Despite becoming a firm favourite with drivers, the race has quickly come one of the most challenging, with a tight and twisty 23-turn circuit, the added impact of racing under lights and the high humidity all working against the men on track.
A Safety Car period every year has meant the race has always run close to its two-hour limit but Button said it would be better for drivers if the race were to be shortened beyond its current length of 61 laps.
Such a move would require special dispensation because of regulations stating a minimum race length – which applies to all races bar Monaco – but Button said it was something that needed to be considered.
"It's a very tough race because it's long, the longest on the calendar, normally about two hours,” he told Sporting Life
. "Mentally it's very tiring because it's low speed, like Monaco in a way with the barriers so close to the circuit, very bumpy, dark, so it's very demanding for the drivers.
"We find it very, very tough, and after the race you are shattered, in pieces. It's one of the races we actually think is a little too long, that they need to maybe shorten.
"We do as much as we can physically, but you can't train for the bumpiness of the circuit, so it's tough for us. I do a lot of work in a hot climate beforehand. This year I was in Japan where it's very humid at the moment, which is great, perfect for Singapore."
Button goes into this weekend on the back of a solid run of form, but with his championship hopes all but over for another year given the gap to points leader Sebastian Vettel.
With that in mind, the McLaren man has just one aim for the weekend ahead.
"Given our current form I'm positive Singapore will be another strong race for us,' he said. "This is one of the races I'd most love to win, and I'm hopeful we'll be able to show the same sort of pace we showed at Monaco and Hungary where I had two of my best drives of the year."
