Formula 1 needs to find ways to bring 'flat out' racing back, claims Red Bull chief Christian Horner, after a boring Canadian Grand Prix.
Horner expressed his frustration after the Montreal race that was dominated by radio calls for drivers to save fuel and their brakes right from the start of the event.
He felt that, as well as a lack of decent action of the front of the field, it delivered the wrong message for Formula 1.
"If you are a fan sitting at home watching that [it's disappointing]," Horner said.
"You want to see the guys going flat out racing each other.
"It is something we need to take on board and react to."
No safety car
The extent of fuel saving in Canada was exacerbated by the lack of a safety car, and the fact that conservative Pirelli tyres meant teams were playing it safe with a one-stop strategy.
Horner added: "One-stop races aren't good for F1. You need to have two to three stops. That is important.
"The tyres that we have are a bit too conservative.
"The other thing that is not good for F1 is fuel saving. I think it should be a sprint race: and lift and coast doesn't belong in a sprint race.
"That is not the message that F1 should be putting across."
When asked what he would do to change things, Horner said: "Shorten the race by five laps or whatever it is.
"Either a bit more fuel or a bit less distance. It needs to be a flat out sprint race from start to finish."
