AlphaTauri discover failure which caused Kvyat’s crash | RaceFans Round-up
In the round-up: AlphaTauri technical director Jody Egginton reveals what led to Daniil Kvyat’s tyre failure and crash in last weekend’s British Grand Prix.
What they say
Kvyat’s right-rear tyre failed before his lap 12 crash. Egginton explained what caused it:
The reason that we were not quick to come forward and say exactly what we thought the issue was, was that Pirelli were doing their analysis in Milan and we were doing our analysis. We’ve come to our conclusion, Pirelli have come to their conclusion, and it fits.
[It was] a rear brake duct we had a problem with. It was degrading and damaged and we had heat migrating to the wrong parts of the brake duct, which then affect heated the rim and that tyre. That got hot and then ultimately that’s what led to the tyre failure.
It took us a few days to arrive at that conclusion because, as you can imagine, there wasn’t much left to look at. Unfortunately is a component degradation which has led to a tyre failure.
“The two Red Bull drivers took new power units this weekend to open up flexibility in terms of PU management, and we will now go through all the data from the 200 laps of running across the four cars to work out the best approach for Saturday and Sunday.”
Ciaron Pilbeam: “Everybody ran the same tyres in the morning session, but we have done something different with our tyres compared to most others in the afternoon, and it will be interesting to see how the consequences of that shake out through the rest of the weekend.”
