How does a company increase the appeal of an outgoing and outdated flagship sedan? If GM had to choose, it would opt to omit the V8 engine.
For those who still recognize the existence of the seemingly forgotten Cadillac STS sedan, this is probably similar to adding insult to injury. But when General Motors announced that it would no longer produce its Northstar V8 engines as of this past July, we knew it was only a matter of time before the STS would no longer offer the 320 hp cast-iron DOHC V8 engine. Additionally, the STS was the sole model in the General Motors lineup that offered the Northstar engine. From now until the Sigma-based sedan is put to rest, the STS will only offer the direct-injected 3.6-liter LLT V6 engine that’s good for 302 hp and 272 lb.-ft. of torque.
The GM Authority Take
It seems that General Motors has officially thrown in the towel for the Cadillac STS. That said, The General’s next-generation Cadillac flagship cannot get here soon enough – but will it be the shimmering XTS, or something more appropriate?
