The title says it all really, but here is the skinny. They are predicting 0-60 in 5.7 seconds with lateral Gs at 0.9 with a solid 8:22 on the Nurburgring which set the lap record for front drive sports compact cars.
It has 260bhp@5300 rpm and 260 ft-lbs @2000 rpm, and weighs in at pretty light 2975lbs too.
That kind of power to weight ratio makes me think it will be a tad quicker to 60mph than 5.7 and can muster a quartermile in the high 13s with a skilled driver who knows how to drag a FWD car.
