Here is what I have on the Huracan Facelift:

1. Huracan Evo (seriously)
2. No more Performante, maybe a Superleggera at some point
3. Exhaust pipes position and especially design similar to Performante (requirement because of the new particulate filter in certain markets)
4. 640 hp (some sources claim 620 hp, similar to Audi R8 facelift but a guy I know was at a dealer event and has been told 640). Personally, I believe 620 hp make more sense but maybe this time, Lamborghini wanted to give the Huracan a "heads up" vs. the R8, who knows?!
5. Touch display in the middle console (similar to Aventador Centenario but smaller).
6. Lower seats, so there is more headroom, especially for those who need to wear a helmet (track).
