Compare the2024 Cadillac LyriqVS 2023 Porsche Cayenne

Both the Lyriq and Cayenne have child safety locks to prevent children from opening the rear doors. The Lyriq 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 Cayenne’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.

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 Lyriq are reminded to check the back seat if they opened the rear door before starting out. The Cayenne doesn’t offer a back seat reminder.

Over 200 people are killed each year when backed over by motor vehicles. The Lyriq has standard Reverse Automatic Braking that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Cayenne doesn’t offer backup collision prevention brakes.

The Lyriq’s standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. A lane departure warning system costs extra on the Cayenne.

The Lyriq has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them and moves the vehicle back into its lane. A system to reveal vehicles in the Cayenne’s blind spot costs extra.

To help make backing out of a parking space safer, the Lyriq’s standard Rear Cross Traffic Alert uses sensors in the rear to alert the driver to vehicles approaching from the side and Rear Cross Traffic Braking automatically engages the brakes to help avoid a collision. The Cayenne doesn’t offer a rear cross-path warning system.

Both the Lyriq and the Cayenne have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras and available around view monitors.

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

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

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Cadillac Lyriq higher (10 out of 10) than the Porsche Cayenne (3 to 5). This means the Lyriq produces up to 36.3 pounds less smog-producing pollutants than the Cayenne every 15,000 miles.

In an emergency stopping situation, many drivers don’t press the brakes with enough force to stop the vehicle in the shortest distance. The Lyriq has standard Intelligent Brake Assist 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 Cayenne doesn’t offer a brake assist feature.

For better traction, the Lyriq has larger standard tires than the Cayenne (265/50R20 vs. 255/55R19).

The Lyriq’s standard tires provide better handling because they have a lower 50 series profile (height to width ratio) that provides a stiffer sidewall than the Cayenne’s standard 55 series front tires.

For better ride, handling and brake cooling the Lyriq has standard 20-inch wheels. Smaller 19-inch wheels are standard on the Cayenne.

The Cadillac Lyriq’s wheels have 6 lugs for longer wheel bearing life, less chance of rotor warping and greater strength. The Porsche Cayenne only has 5 wheel lugs per wheel.

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

For a smoother ride and more stable handling, the Lyriq’s wheelbase is 7.8 inches longer than on the Cayenne (121.8 inches vs. 114 inches).

The Lyriq’s front to rear weight distribution is more even (48.7% to 51.3%) than the Cayenne’s (53.6% to 46.4%). This gives the Lyriq more stable handling and braking.

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

The Lyriq has 3.2 inches more front legroom and 2.1 inches more rear shoulder room than the Cayenne.

The Lyriq has a larger cargo volume with its rear seat up than the Cayenne with its rear seat up (28 vs. 27.2 cubic feet). The Lyriq has a larger cargo volume with its rear seat folded than the Cayenne with its rear seat folded (60.8 vs. 60.3 cubic feet).

A low lift-over cargo hatch design makes loading and unloading the Lyriq easier. The Lyriq’s cargo hatch lift-over height is 28.5 inches, while the Cayenne’s liftover is 31 inches.

Pressing a switch automatically lowers the Lyriq Luxury/Sport’s optional rear seats, to make changing between passengers and cargo easier. The Cayenne doesn’t offer automatic folding seats.

J.D. Power and Associates surveys of service recipients show that Cadillac service is better than Porsche. J.D. Power ranks Cadillac second in service department satisfaction. With a 1% lower rating, Porsche is ranked third.

The Lyriq 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 Cayenne doesn’t offer a remote starting system.

The Lyriq’s standard easy entry system raises the steering wheel and glides the driver’s seat back, making it easier for the driver to get in and out. An easy entry system costs extra on the Cayenne.

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

The Lyriq’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 Cayenne’s cruise control switches are unlit, making them difficult to find at night and operate safely.

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

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Cadillac Lyriq has a standard wireless phone charging system (Qi) in the center console. Wireless charging costs extra on the Cayenne.

The Lyriq offers an optional 115-volt a/c outlet on the center console, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The Cayenne doesn’t offer a house-current electrical outlet.
