That's not bad, considering the limited displacement and torque. It makes good numbers for what it is.
As a comparison, this is a 4,680 lb B-Body with naturally aspirated (modified) LT1 on cast iron exhaust. The numbers translate to about 5.1 seconds to 60+ MPH, and under 8 seconds to 95 MPH. There's a LOT more torque available there, however, and the ATS is not a skateboard - There is some mass there as well.
