The CT6’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Model S doesn’t offer pre-crash pretensioners.

For enhanced safety, the front seat shoulder belts of the Cadillac CT6 are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The Tesla Model S doesn’t offer height-adjustable seat belts.

In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the CT6 are reminded to check the back seat if they opened the rear door before starting out. The Model S doesn’t offer a back seat reminder.

The CT6’s standard pretensioning seatbelts also sense rear collisions and remove slack from the front seatbelts to help protect the occupants from whiplash and other injuries. The Model S doesn’t offer a whiplash protection system.

Over 200 people are killed each year when backed over by motor vehicles. The CT6 Premium Luxury/Platinum has standard Reverse Automatic Braking that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The Model S doesn’t offer backup collision prevention brakes.

An active infrared night vision system standard on the CT6 Premium Luxury/Platinum helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera and near-infrared lights to detect heat, the system then displays the image on a monitor in the dashboard. The Model S doesn’t offer a night vision system.

The CT6 Premium Luxury/Platinum has a standard Surround Vision to allow the driver to see objects all around the vehicle on a screen. The Model S only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.

To help make backing safer, the CT6’s cross-path warning system uses wide-angle radar in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The Model S doesn’t offer a cross-path warning system.

The CT6 has standard OnStar®, which uses a global positioning satellite (GPS) receiver and a cellular system to get turn-by-turn driving directions, remotely unlock your doors if you lock your keys in, help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The Model S doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.

Both the CT6 and the Model S have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems and rearview cameras.

The CT6’s corrosion warranty is 2 years and unlimited miles longer than the Model S’ (6/unlimited vs. 4/50,000).

There are over 6 times as many Cadillac dealers as there are Tesla dealers, which makes it much easier should you ever need service under the CT6’s warranty.

The CT6’s maximum EPA estimated driving range on a full tank of fuel is 518.4 miles, after which it can be refueled at any gas station in minutes. The Model S’ range is only 348 miles, after which the minimum recharge time is 30 minutes for only a 54% charge at a specially configured quick charge station not available in most areas. A full recharge at a conventional charging station can take up to 82 hours and 53 minutes.

14 inches

In an emergency stopping situation, many drivers don’t press the brakes with enough force to stop the vehicle in the shortest distance. The CT6 has a standard brake assist system to detect emergency braking situations (by how hard and how quickly the brake pedal is pressed) and then automatically apply maximum braking immediately in order to help prevent a collision. The Model S doesn’t offer a brake assist feature.

The CT6 has a standard easy tire fill system. When inflating the tires, the vehicle’s integrated tire pressure sensors keep track of the pressure as the tires fill and tell the driver when the tires are inflated to the proper pressure. The Model S doesn’t offer vehicle monitored tire inflation.

The CT6 has a standard space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the Model S; it requires you to depend on roadside assistance and your vehicle will have to be towed.

The Cadillac CT6 may be more efficient, handle and accelerate better because it weighs about 300 to 800 pounds less than the Tesla Model S.

The CT6 uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The Model S doesn’t offer active noise cancellation.

The CT6 has 27.2 cubic feet more passenger volume than the Model S (121.2 vs. 94).

The CT6 has 1.4 inches more front headroom, 3.7 inches more front legroom, .9 inches more front hip room, .6 inches more front shoulder room, 2.7 inches more rear headroom, 5 inches more rear legroom and 1.2 inches more rear shoulder room than the Model S.

With its sedan body style and remote trunk release lockout, the CT6 offers cargo security. The Model S’ hatchback body style and non-lockable folding seat defeat cargo security.

To make loading groceries and cargo easier when your hands are full, the CT6’s trunk can be opened and closed just by kicking your foot under the back bumper, leaving your hands completely free. The Model S doesn’t offer a hands-free gesture to open its liftgate, forcing you to put cargo down if your hands are full.

A maintenance reminder system is standard on the CT6 to save the owner time and money by calculating maintenance intervals for oil changes and air filter replacement based on actual driving conditions. This takes the guesswork out of keeping your vehicle in top condition and helps it last longer. Tesla doesn’t offer a maintenance reminder on the Model S.

Unlike the driver-only memory system in the Model S, the CT6 Premium Luxury/Platinum has a passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position, suspension setting, outside mirror angle and radio stations and the front passenger seat also adjusts to the new passenger’s preset preferences.

The CT6 Premium Luxury/Platinum offers an optional heads-up display that projects speed and other key instrumentation readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Model S doesn’t offer a heads-up display.

On a hot day the CT6’s driver can lower all the windows from a distance using the keyless remote. The driver of the Model S can only operate the windows from inside the vehicle, with the ignition on.

The CT6’s power window, power lock, power mirror and cruise control switches are lit from behind, making them plainly visible and easier to operate at night. The Model S’ cruise control switches are unlit, making them difficult to find at night and operate safely.

The CT6’s standard side window demisters help clear frost or condensation from the side windows in the winter. The Model S doesn’t even offer side window demisters, so the driver may have to wipe the windows from the outside to gain side vision.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the CT6 has standard extendable sun visors. The Model S doesn’t offer extendable visors.

A power rear sunshade and manual rear side window sunshades are standard in the CT6 Premium Luxury/Platinum to help block heat and glare for the rear passengers. The Model S doesn’t offer a rear sunshade.

The CT6 Premium Luxury/Platinum has standard front air conditioned seats and the CT6 Platinum also has them in the rear. This keeps the passengers comfortable and takes the sting out of hot seats in summer. The Model S doesn’t offer air-conditioned seats.

The CT6 Platinum has standard massaging front and rear seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the Model S.

According to The Car Book by Jack Gillis, the CT6 is less expensive to operate than the Model S because typical repairs cost much less on the CT6 than the Model S, including $377 less for a water pump and $383 less for a power steering pump.
