I think we should give them more credit than saying it's a slightly modified Dallara lmp2 chassis also. The differences are big if you look closer at the car. It's hard to spot with the bare carbon color but the roof is different, the splitter and front nose is different, the sidepods, the rear wing etc. That's just bodywork, underneath the car I'm sure is hugely different as well. Plus lmp1's run different dimensions in terms of length. I like this little touch with the headlights!
