The McLaren P1 has a centrally mounted exhaust. And the times that it isn't spitting flames are rarer than the times it is spitting flames. Simply put, this is basically a car with a damn afterburner.
We've already seen Chris Harris have his time in the P1 at Yas Marina Circuit, but Evo also got a chance in the car at the same time. Is what Dickie Meaden says about the P1 appreciably different to what Chris says?
