A disappointing day. The damp weather pushed the emphasis onto aerodynamic testing, but this was cut short by a failure of the revised seal introduced today in a bid to resolve the week’s MGU-K issues.
To compound a tricky day, Jenson suffered a punctured Intermediate tyre during a practice pitstop, coming to a halt before the end of the pitlane.
“Yesterday wasn’t bad, with more mileage and lots of data gathered, but today’s been tricky – it hasn’t been my day. We had a similar problem to the one we faced on Thursday, with the faulty MGU-K seal, so the afternoon running was limited to aero testing and pitstop practice.
“I still can’t comment on where the car will be when everything is running smoothly, as I haven’t had the chance to run it properly without meeting problems. Having said that, I feel like there’s definitely nothing wrong with the car or any stand-out issues with driveability. You jump in the car and everything feels good.
“Hopefully, our problems will be solved sooner rather than later, but tomorrow is still likely to be a reasonably difficult day. There’s a lot for us to improve at the moment – we’ve still got five days of testing left, so hopefully they’ll be five good days.”
