1. They have really reinvented the sports car and bested everyone by a significant margin. Maybe it could be their AWD system.
2. The car is under rated in term of power
3. The car is under rated in terms of weight (claimed>actual)
4. The car had street legal race tires
What is the most likely scenario. I'd vote in order 4,3,2,1.
It makes some sense if the car tested was the speculated 530 hp version. Otherwise, I'd go with: 4, 2, 3, 1.
