Compare the2024 Cadillac CT5-VVS 2023 Porsche Panamera

The CT5-V Blackwing’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Panamera doesn’t offer pre-crash pretensioners.

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 CT5-V are reminded to check the back seat if they opened the rear door before starting out. The Panamera doesn’t offer a back seat reminder.

Over 200 people are killed each year when backed over by motor vehicles. The CT5-V (except Manual) 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 Panamera doesn’t offer backup collision prevention brakes.

The CT5-V 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. A system to reveal vehicles in the Panamera’s blind spot costs extra.

To help make backing out of a parking space safer, the CT5-V’s standard Rear Cross Traffic Alert uses sensors in the rear to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The Panamera doesn’t offer a rear cross-path warning system.

Both the CT5-V and the Panamera 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, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, lane departure warning systems, rearview cameras, available all wheel drive and around view monitors.

Cadillac’s powertrain warranty covers the CT5-V 2 years and 20,000 miles longer than Porsche covers the Panamera. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the Panamera 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 CT5-V’s warranty.

The CT5-V has more powerful engines than the Panamera:

On the EPA test cycle the CT5-V gets better mileage than the Panamera Sedan running its gasoline engine:

The CT5-V 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 Panamera doesn’t offer a cap-less fueling system.

A 10-speed automatic is standard on the Cadillac CT5-V, for better acceleration and lower engine speed on the highway. Only an eight-speed automatic is available for the Panamera.

In an emergency stopping situation, many drivers don’t press the brakes with enough force to stop the vehicle in the shortest distance. The CT5-V 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 Panamera doesn’t offer a brake assist feature.

The CT5-V stops shorter than the Panamera:

The CT5-V’s standard tires provide better handling because they have a lower 40 series profile (height to width ratio) that provides a stiffer sidewall than the Panamera’s standard 45 series front tires.

The CT5-V 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 Panamera doesn’t offer vehicle monitored tire inflation.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires available on the CT5-V can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The Panamera doesn’t offer run-flat tires.

The CT5-V Blackwing handles at 1.02 G’s, while the Panamera 4 pulls only .94 G’s of cornering force in a Car and Driver skidpad test.

The Cadillac CT5-V may be more efficient, handle and accelerate better because it weighs about 250 to 1250 pounds less than the Porsche Panamera.

The CT5-V is 5 inches shorter than the Panamera, making the CT5-V easier to handle, maneuver and park in tight spaces.

The CT5-V has 3 cubic feet more passenger volume than the Panamera (99 vs. 96).

The CT5-V has 1 inch more front headroom, .5 inches more front legroom, 2.3 inches more rear legroom and 1.4 inches more rear shoulder room than the Panamera.

A low lift-over trunk design makes loading and unloading the CT5-V easier. The CT5-V’s trunk lift-over height is 27.8 inches, while the Panamera’s liftover is 29.7 inches.

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 CT5-V (except Blackwing Manual) 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 Panamera doesn’t offer a remote starting system.

The CT5-V’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 Panamera.

On a hot day the CT5-V’s driver can lower all the windows from a distance using the keyless remote. The driver of the Panamera can only operate the windows from inside the vehicle, with the ignition on.

The CT5-V’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 Panamera’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 CT5-V has standard extendable sun visors. The Panamera doesn’t offer extendable visors.

The CT5-V (except Manual)’s optional Automatic Parking Assist with Braking can parallel park by itself, starting and stopping automatically, with the driver only responsible for switching from reverse to drive. The Panamera doesn’t offer an automated parking system.

The CT5-V Blackwing was chosen as a Car and Driver’s “Top Ten” for 2023 and 2022. The Panamera has never been chosen by Car and Driver in their “10Best” issue.

The Cadillac CT5 outsold the Porsche Panamera by over five to one during 2022.
