As you’re probably aware, Cadillac has different tiers for its performance vehicles. V-Sport cars make up the tier underneath full V-Series models that provide the most power. It’s much like how there’s a difference between the BMW M550i and the M5. Perhaps to give its flagship sedan an image boost, Cadillac is renaming the CT6 V-Sport to CT6-V, without making any mechanical changes.
Despite the new name, the Cadillac CT6-V will make the same 550 hp and 627 lb-ft of torque that the CT6 V-Sport debuted with earlier this year. This power comes from a hand-built 4.2-liter twin-turbo V-8 that GM calls the Blackwing. It produces significantly less power than another full V-Series model, the not-long-for-this-world CTS-V, which is rated at 640 hp and 630 lb-ft of torque.
“Beginning with the debut of the CTS-V Sedan in 2004, the V-Series sub-brand sparked new life into Cadillac,” said Mark Reuss, executive vice president and president of GM Global Automotive Group and Cadillac, in a release. “As a result of the overwhelming response the CT6 V-Sport received when revealed in early 2018, we’ve decided to formally make it a V-Series, signaling the expansion of V-Series.”
GM also announced that CT6 Platinum models will get a version of the 4.2-liter engine, which was previously said to be exclusive to the V-Sport. The engine will be detuned to 500 hp and 553 lb-ft in the Platinum trim, however.
The CT6-V is expected to arrive this spring. In addition to the CT6-V, Cadillac says it will expand the V-Series with new variants across the entire lineup starting in 2019. It’s unclear if this includes crossovers like XT4 and XT5, but Caddy say the new V models would get upgraded propulsion systems and brake systems, as well as chassis updates.
