Cadillac has apparently allowed a little over a thousand CT4s to leave the factory with 450T badges instead of the correct 500T badges, per a report from Cadillac Society.

Okay, so the badges are a reference to the car's power, but not its horsepower, its torque instead, and not in pound-feet like we use in America where the car is made, sold, and designed, but in Newton-meters, like they use in Europe, and the numbers aren't exact, they're rounded up to the nearest 50. Got that? Good. Because apparently, Cadillac doesn't.

The CT4 450T 500Ts in question make use of the optional 2.7-liter I4 that produces 310 hp and 350 lb-ft of torque in the Premium Luxury (it makes more in the V). That amounts to 475 Nm of torque-hence the 500 badge. The 2.0-liter engine makes 258 lb-ft of torque or 350 Nm. 

That leads to the most mystifying part of this story, which is that there don't appear to be any CT4s that should wear a 450T badge. 

The solution is pretty simple, Cadillac will take off your 450 badge and give you a 500 one free of charge. Might be fun to keep the 450, though, since it will make your car one of the rare thousand that came from the factory with an error. Is that the kind of thing that forum nerds will be obsessing over in 50 years?
