I love watching racing so sprint races are not a total disaster as far as I am concerned. However, they would have to do something to make the sprint race different to the main race. In World Superbike they do this by having a completely different tyre for the sprint race. The outcome can result in different bike/rider performances between the sprint race and the main race. In F1 they could have different 'sprint tyres' plus they could chose to run old engines turned up to 11 in a 'win or explode' approach (this would only be true if the race was for half points and didn't change qualifying for the main race).
I doubt it will happen but I also think they need to make F1 more interesting for a wider audience.
A great way to recycle parts too. Everyone makes more engines and gearboxes than they are allowed to race, so allow used and rebuilt bits and send them out.
It’s simply a way to spice up qualifying which seems to change format every couple of races anyway, and quite honestly the excitement for me in Q only comes in the last few seconds of each session, so a couple of fun filled sprint races is just fine with me.
Using special tires that may jumble the order a bit depending on how the cars behave with the different compounds or more importantly how the various cars affect the tire performance, would make things all that more interesting.
Until they wipe out the aero shadow so that cars can actually close on one another and pass un-aided by gimmicks like DRS, I’m for anything else that tweaks interest.
