As we reported last week, the 2020 Cadillac CT4 Premium Luxury with the available turbocharged 2.7L I4 L3B gasoline engine wears the ‘500T’ badge on its tailgate, as per Cadillac’s new torque-based naming scheme. A handful of 2020 Cadillac CT4 models with the uprated turbo four-cylinder were shipped with incorrect ‘450T’ badges rather than ‘500T’ badges, however, so GM has now issued a TSB to instruct dealers on how to remedy the issue.
According to the TSB, roughly 1,155 examples of the 2020 Cadillac CT4 were shipped with ‘450T’ badges instead of ‘500T’ badges. Dealerships will remove the incorrect badge and replace it with the correct one. This work will be performed at no cost to the owner and should only take around 20 minutes to complete. GM is also instructing dealers to perform this fix on any vehicles that are sitting on lots and have yet to be sold.
The Cadillac CT4 Premium Luxury with the available 2.7L engine produces 310 horsepower and 350 pound-feet of torque. Cadillac’s torque badging strategy is based on the given vehicle’s maximum torque output measured in newton meters, and then rounded up to the nearest number divisible by 50. The Cadillac CT4 Premium Luxury with the 2.7L engine produces the equivalent of 475 newton meters of torque, so GM rounded up to 500 to get the ‘500T’ designation.
The 2020 Cadillac CT4 comes standard with a turbocharged GM 2.0L I4 LSY gas engine, which produces 237 horsepower and 258 pound-feet of torque. Converted to newton meters, the 258 pound-feet figure is equivalent to about 350 newton meters, so the standard CT4 receives ‘350T’ badge. The only Cadillac CT4 variant that does not receive one of these torque-based badges is the performance-focused CT4-V, which has a more powerful version of the 2.7L L3B engine good for 325 horsepower and 380 pound-feet of torque.
