We Blew Up the Engine in Our Cadillac CT5-V Blackwing During Initial Testing

If they’re keeping the car for 40k miles as they state, there’s plenty to test and review in a car while waiting for a 1500mi break in period. I don’t see why they wouldn’t respect it as journalists.

And even if they didn’t fully follow spec, having the engine literally explode after a few hard pulls immediately afterwards is a horrible outcome. No engine should do that, as there’s bound to be plenty of regular users that don’t actually wait the full 1500mi period.

The ECU puts you in what's basically valet mode until you hit the mileage.
