EuroNCAP ratings are harsher, so not really. It's mostly that the US system is based on SUVs and other behemoths. Look at the new small Toyota Yaris. That's what is required to get a good rating these days. Most newish SUVs doesn't even have the same amount of safety systems (like airbags between driver and front passenger seat).
I was speaking solely about regulatory requirements (i.e FMVSS) for selling a vehicle, not the NCAP programs. It is generally legal to sell vehicles with bad NCAP scores. For instance: the 2018 Fiat Panda met EU regulations to be sold but scored 0 stars on EuroNCAP.
But when it comes to expensive systems like crash structures, active and passive safety systems, the US requires a lot.
