Lewis Hamilton reveals Ferrari upgrade mystery: 'It's not normal'

Lewis Hamilton has explained a mystery surrounding Ferrari's Austrian Grand Prix upgrade package after detailing a "not normal" trait with it. 

The Scuderia is bringing fresh parts to the Red Bull Ring as it looks to regain the second place it lost in the constructors' to Mercedes in Canada, with Hamilton also still searching for a maiden grand prix podium for the team. 

Hamilton had called for fresh upgrades last time out in Montreal, with Ferrari delivering, but the seven-time champion has explained how the team will receive "not the normal information" gathered to determine whether the new package has been successful. 

"Firstly, I am happy that we have an upgrade, it is always exciting to get new pieces on the car," Hamilton told media, including RacingNews365. 

"So I am really grateful for everyone working hard to bring them, but we don't really know the actual effect it is going to have.

"It's not the normal information we're getting of much much load you've added to the car, it is not necessarily clear, but hopefully it will be a step in the right direction, but I wouldn't think we're expecting it to change a huge amoubnt, but fingers crossed it is better."

Hamilton was then pushed on his adjustment into Ferrari following a difficult start to the season, but was firm that he did not want to "make excuses."

"I've spoken so much about it, so I don't particularly want to give you more insight into it, because, and I am not making excuses, we were second in the constructors' before the last race, and we've had many problems in both sides, driver and car, but we are working towards it.

"The positive is that we are making improvements, we are progressing, whether or not you see that is not necessarily important to me. 

"Personally, I feel like I am making progress, we are making progress, and that is what is most important."
