Yes, our roommate has one. We even directly compared the acceleration to our AWD Model 3. They go about the same from a dead stop, but the AWD rapidly gains ground above 30 MPH. We also compared our AWD to a P and the P takes off like a rocket.
It has very good power. Just going for a ride in the passenger's seat, I couldn't discern much of a difference between it and our car ... it's smooth and deceptively quick.
Too soon to tell on the efficiency, as he only has 1,000 miles on it. We did test Supercharging and it can do triple digits (over 100 kW) when the battery is warm.
