Safety Comparison

Over 200 people are killed each year when backed over by motor vehicles. The CT6 (except Base/Luxury) offers optional Rear Automatic Braking which use rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The A7 doesn’t offer backup collision prevention brakes.

The CT6 Luxury/Premium/Platinum has a standard Surround Vision to allow the driver to see objects all around the vehicle on a screen. The A7 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 optional 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 A7 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 A7 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 A7 have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, height-adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available crash mitigating brakes, night vision systems, lane departure warning systems and blind spot warning systems.

Warranty Comparison

Cadillac’s powertrain warranty covers the CT6 2 years and 20,000 miles longer than Audi covers the A7. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the A7 ends after only 4 years or 50,000 miles.

Cadillac pays for scheduled maintenance on the CT6 for 3 years and 36,000 miles. Cadillac will pay for oil changes, lubrication and any other required maintenance. Audi only pays for the first scheduled maintenance visit on the A7.

There are over 3 times as many Cadillac dealers as there are Audi dealers, which makes it much easier should you ever need service under the CT6’s warranty.

Engine Comparison

The CT6 has more powerful engines than the A7:




CT6 3.6 DOHC V6

335 HP

285 lbs.-ft.

CT6 3.0 turbo V6

Fuel Economy and Range Comparison

An engine control system that can shut down half of the engine’s cylinders helps improve the CT6 V6’s fuel efficiency. The A7 doesn’t offer a system that can shut down part of the engine.

The CT6 has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The A7 doesn’t offer a cap-less fueling system.

Brakes and Stopping Comparison

The CT6 stops much shorter than the A7:





70 to 0 MPH

152 feet

166 feet

Suspension and Handling Comparison

The CT6 offers an optional driver-adjustable suspension system. It allows the driver to choose between an extra-supple ride, reducing fatigue on long trips, or a sport setting, which allows maximum control for tricky roads. The A7’s suspension doesn’t offer adjustable shock absorbers.

For a smoother ride and more stable handling, the CT6’s wheelbase is 7.7 inches longer than on the A7 (122.4 inches vs. 114.7 inches).

The CT6’s front to rear weight distribution is more even (51.2% to 48.8%) than the A7’s (54.8% to 45.2%). This gives the CT6 more stable handling and braking.

The CT6 AWD handles at .86 G’s, while the A7 3.0T pulls only .84 G’s of cornering force in a Car and Driver skidpad test.

The CT6 AWD executes Motor Trend’s “Figure Eight” maneuver quicker than the A7 (25.4 seconds @ .75 average G’s vs. 25.8 seconds @ .71 average G’s).

Chassis Comparison

The Cadillac CT6 may be more efficient, handle and accelerate better because it weighs up to about 600 pounds less than the Audi A7.

The front grille of the CT6 uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The A7 doesn’t offer active grille shutters.

The CT6 offers available computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The A7 doesn’t offer active noise cancellation.

As tested by Car and Driver while cruising at 70 MPH, the interior of the CT6 is quieter than the A7 3.0T (66 vs. 68 dB).

Passenger Space Comparison

The CT6 has 27.2 cubic feet more passenger volume than the A7 (121.2 vs. 94).

The CT6 has 3.2 inches more front headroom, 1.1 inches more front legroom, 1 inch more front shoulder room, 1.4 inches more rear headroom, 3.4 inches more rear legroom and .3 inches more rear shoulder room than the A7.

For enhanced passenger comfort on long trips the CT6’s available rear seats recline. The A7’s rear seats don’t recline.

Cargo Capacity Comparison

With its sedan body style and remote trunk release lockout, the CT6 offers cargo security. The A7’s hatchback body style and non-lockable folding seat defeat cargo security.

Ergonomics Comparison

The CT6 has a standard remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The A7 doesn’t offer a remote starting system.

The CT6’s instruments include an oil pressure gauge and a temperature gauge – which could save your engine! Often ‘idiot lights’ don’t warn you until damage has been done. The A7 does not have an oil pressure gauge.

A power rear sunshade is optional in the CT6 to help block heat and glare for the rear passengers. The A7 doesn’t offer a rear sunshade.

Optional air conditioned front and rear seats keep the CT6’s passengers comfortable and take the sting out of hot leather in Summer. The A7 doesn’t offer air conditioned seats in the rear.

The CT6 Luxury/Premium/Platinum has a 115-volt a/c outlet, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The A7 doesn’t offer a house-current electrical outlet.

The CT6 Luxury/Premium/Platinum’s Automatic Park Assist can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The A7 doesn’t offer an automated parking system.
