I am not supposed to publish 'driving impressions' of the new Corvette ZR1 which I drove today at General Motors' Proving Grounds in Milford Michigan before next Wednesday.
And, tell you that the supercharged 6.2 litre V8 engine produces 638 horsepower - a number which actually has been raised twice since the first official press information was released some months ago - and 604 lb.-ft. of torque
And, that it is shod with massive, developed-specifically-for-the-car Michelin Pilot Sport 2 tires, P285/30ZR19 front, P335/25ZR20 rear.
And, that it is stopped by gigantic Brembo composite brakes.
And, that driven by one of the car's engineers,
Jim Merrill, it set a new fastest-ever production-car lap time on the Nurburgring's Nordschleife circuit of 7 minutes 26 seconds, beating the former short-lived record held by Nissan's GT-R by three seconds.
Which also makes it faster there than such as the Porsche Carrera GT, Ferrari Enzo - well, anything, really.
So, how bad could it be to drive?
You will have to wait until the print edition of Wheels shows up for the weekend after this coming Saturday to find out.
But I think you can probably guess.
