Overview
The Cadillac CT6 is the brand’s largest and poshest sedan, competing with the Lincoln Continental, Acura RLX, BMW 5 Series, and Volvo S90. For 2020, it soldiers on with minor updates.
Sometime last year, the base 4-cylinder engine disappeared from the lineup. That leaves a 3.6-liter V6 as the new base engine, making 335 horsepower and 284 pound-feet of torque. Also gone is last year’s twin-turbocharged V6. In its stead is a more potent twin-turbocharged 4.2 liter V8 that measures 500 hp and 574 lb-ft. Both engines hook up to a 10-speed automatic transmission and standard all-wheel drive (AWD). Even the standard suspension setup is composed, but Cadillac offers a magnetic ride setup and active rear steering above that.
This year, the CT6 comes in Luxury, Premium Luxury, and Platinum grades. The Luxury includes 19-inch alloy wheels, LED exterior lighting, a panoramic power sunroof, heated front seats, heated outside mirrors, keyless access and start, 14-way power seats, memory settings, dual-zone automatic climate control, leather upholstery, an 8-inch instrument cluster LCD, a 10.2-inch infotainment system with Apple CarPlay and Android Auto connectivity, and 4G LTE hotspot capability. Features on higher trims consist of a 12-inch instrument cluster LCD, ventilated front seats, heated rear outboard seats, backseat entertainment screens, 4-zone climate control, 20-inch wheels, a rear spoiler, and a Bose Panaray system with 34 speakers.
As befitting a vehicle of its stature, the CT6 comes with an excellent array of standard and optional safety features. Every model gets forward-collision warning, automatic emergency braking, a safety-alert seat, a following-distance indicator, lane-keeping assist, lane-departure warning, rear cross-traffic alert, and blind-spot monitoring. Adaptive cruise control, enhanced automatic emergency braking, reverse automatic braking, night vision, and Super Cruise come standard on Premium Luxury and above trims. Super Cruise is a semi-autonomous driving function that works on certain divided-access highways. No major agency has crash-tested the CT6, but that’s pretty normal for large luxury sedans.

Is the 2020 Cadillac CT6 reliable?
Owners rate it 4/5, a solid signal of long-term satisfaction. That kind of owner feedback suggests the 2020 CT6 can be a reasonable used-car choice if you prioritize a well-kept example and verify its history before buying.

What should I look for when buying a used 2020 Cadillac CT6?
At 58.2% accident-free, a meaningful share of listings has prior incidents — history verification is especially important. You should run a vehicle history report on any CT6 you’re considering and give extra attention to signs of past bodywork, paint mismatch, or uneven panel gaps. A pre-purchase inspection should focus on overall condition, since the best buy is likely the one with the cleanest history and the most consistent maintenance record.

Should I buy a 2020 Cadillac CT6 or consider a different year?
If you're weighing the 2020 against nearby model years, here's how to think about it:
Choose the 2020 if:
- 32.8% of listings are priced as good or great deals.
- At 58.2% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
- Owners rate it 4/5 — a solid satisfaction signal.
