I am VERY dubious of the sub 5 second 0-60 time for the GRC. There is no way it is quicker off the line than the GRY (the GRY is capable of 4.8 0-100 (62 mph))"Toyota GR Yaris AWD Hot Hatch Does 0 To 60 MPH In 5.3 Seconds"

But once it has momentum on like a rolling lap of a track it may be quicker.
