This sounds very dubious, unless it has negative aerodynamic downforce. Even then, the times for each successive mph drop off too fast for it to be traction limited. Even F1 cars are not traction limited for more than a brief spell of straight-line acceleration. Aero drag dominates very quickly.
[My caveat on this, I'm not a road-car enthusiast, so I'm just deducing. But I used to work in motor racing, mostly bikes. Based on the standard of reporting I saw about stuff I did know well, I don't trust the motor press on tech claims.]

Cornering or braking, on the other hand...
