Cadillac CT6

Overview

The Cadillac CT6 was one of the most technologically ambitious American luxury sedans ever produced. Introduced for model year 2016, the CT6 was built on a revolutionary multi-material spaceframe that combined aluminum, high-strength steel, and magnesium to create a structure that was simultaneously lighter and more rigid than conventional steel construction. This engineering approach — borrowed from aerospace thinking — gave the CT6 a curb weight competitive with European rivals despite its full-size dimensions, resulting in a luxury sedan that drove with surprising agility for its class.

Technology was the CT6's defining story. Super Cruise — Cadillac's hands-free highway driving system using LiDAR map data, GPS, and driver attention monitoring — debuted on the CT6 in 2018 and was considered the most sophisticated Level 2 driver assistance system available from any manufacturer. The available Bose Performance Series audio system with active noise cancellation represented a new benchmark for automotive audio. The standard 360-degree camera system with rear camera mirror, night vision, and pedestrian detection made the CT6 one of the safest full-size sedans in production.

The CT6 was available with an impressive range of powertrains from the 265 hp 2.0-litre turbocharged four-cylinder to the formidable 4.2-litre twin-turbocharged V8 — initially installed in the CT6-V Blackwing producing 550 horsepower, making it the most powerful Cadillac since the 1970s muscle car era. A plug-in hybrid variant (CT6 PHEV) was produced exclusively in China using a different 2.0-litre engine with electric motors. Despite critical acclaim for its technology and driving dynamics, the CT6 sold modestly and was discontinued in 2020, making surviving examples increasingly collectible — particularly the rare CT6-V Blackwing.
