For enhanced safety, the front and rear seat shoulder belts of the Rolls-Royce Phantom have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision. The Cadillac CT6 doesn’t offer pretensioners for the rear seat belts.

Both the Phantom and CT6 have child safety locks to prevent children from opening the rear doors. The Phantom has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The CT6’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.

The Phantom has standard PostCrash, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The CT6 doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

The Phantom’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The CT6 doesn’t offer a driver alert monitor.

Both the Phantom and the CT6 have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights and rearview cameras.

The Rolls-Royce Phantom weighs 1218 to 2046 pounds more than the Cadillac CT6. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.

The Phantom comes with a full 4-year/unlimited-mile basic warranty, which covers the entire car and includes 24-hour roadside assistance. The CT6’s 4-year/50,000-mile basic warranty expires sooner.

Rolls-Royce pays for scheduled maintenance on the Phantom for 1 year and -36,000 miles longer than Cadillac pays for maintenance for the CT6 (4/unlimited vs. 3/36,000).

To lower fuel costs and make buying fuel easier, the Rolls-Royce Phantom uses regular unleaded gasoline (premium recommended for maximum performance). The CT6 with the 3.0 turbo V6 engine requires premium, which can cost 20 to 55 cents more per gallon.

The Phantom has 4.3 gallons more fuel capacity than the CT6 (23.8 vs. 19.5 gallons), for longer range between fill-ups.

Tires and Wheels

For better traction, the Phantom has larger standard tires than the CT6 (255/45R22 vs. 235/50R18). The Phantom’s tires are larger than the largest tires available on the CT6 (285/45R21 vs. 245/45R19).

The Phantom’s tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the CT6’s standard 50 series tires.

For better ride, handling and brake cooling the Phantom has standard 21-inch wheels. Smaller 18-inch wheels are standard on the CT6. The Phantom’s optional 22-inch wheels are larger than the 20-inch wheels optional on the CT6.

Having a flat tire is dangerous, inconvenient and expensive. The self-sealing tires available on the Phantom can automatically seal most punctures up to 3/16 of an inch, effectively preventing most flat tires. The CT6 doesn’t offer self-sealing tires.

The Phantom has active sway bars, which help keep it flat and controlled during cornering, but disconnect at lower speeds to smooth the ride and offer greater off-road suspension articulation. This helps keep the tires glued to the road on-road and off. The CT6 doesn’t offer an active sway bar system.

The front and rear suspension of the Phantom uses air springs for a smoother, controlled ride than the CT6, which uses coil springs. Air springs maintain proper ride height and ride more smoothly.

The Phantom offers an available adjustable active suspension system, which counteracts cornering forces actively, limiting body roll and improving handling and stability. Cadillac doesn’t offer an active suspension on the CT6.

The Phantom has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The CT6 doesn’t offer a load leveling suspension.

For a smoother ride and more stable handling, the Phantom’s wheelbase is 17.4 inches longer than on the CT6 (139.8 inches vs. 122.4 inches). The Phantom EWB’s wheelbase is 26.1 inches longer than on the CT6 (148.5 inches vs. 122.4 inches).

The Phantom has a much larger trunk than the CT6 (19 vs. 15.8 cubic feet).

A standard locking glovebox (which can’t be accessed with the valet key) keeps your small valuables safer in the Phantom. The CT6 doesn’t offer locking storage for small valuables.

Heated windshield washer nozzles are standard on the Phantom to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The CT6 doesn’t offer heated windshield washer nozzles.

The CT6 Premium Luxury/Platinum/Sport’s cornering lamps activate a lamp on the front corner when the turn signal is activated. The Phantom’s standard adaptive cornering lights turn the actual headlight unit up to several degrees, depending on steering wheel angle and vehicle speed. This lights a significant distance into corners at any speed.

The Phantom has a standard heated steering wheel to take the chill out of steering on extremely cold winter days before the car heater warms up. A heated steering wheel is only available on the CT6 Premium Luxury/Platinum/Sport.
