Cadillac's true flagship—a technological tour de force with rear-wheel drive and a twin-turbo V8 that's more art than engine. It's a masterpiece, but it's a rare, expensive masterpiece that was killed too soon.
The CT6 was a full-size luxury sedan on the GM Omega platform (rear-drive). Engines: 2.0L Turbo I4 (265 hp), 3.6L V6 (335 hp), 3.0L twin-turbo V6 (404 hp), or 4.2L twin-turbo V8 (550 hp in the CT6-V). Transmissions: 8-speed auto or 10-speed auto.
The CT6 is a rare car. The 3.0L twin-turbo V6 is a good engine, but it's complex. The CT6-V's V8 is a high-strung engine. The 10-speed automatic has some issues. The CT6 is a great car to drive, but it's expensive to maintain. It was discontinued in the U.S. because it didn't sell well.
