The Panamera offers available whiplash protection, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the whiplash protection system moves the headrests forward to prevent neck and spine injuries. The CTS-V doesn’t offer a whiplash protection system.

The Panamera offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The CTS-V doesn’t offer all-wheel drive.

A passive infrared night vision system optional on the Panamera helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera to detect heat, the system then displays the image on a monitor in the dashboard and even aims one of the vehicle’s headlights in the direction of the person or object. The CTS-V doesn’t offer a night vision system.

The Panamera offers an optional Surround View System to allow the driver to see objects all around the vehicle on a screen. The CTS-V 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.

Both the Panamera and the CTS-V have standard driver and passenger frontal airbags, front and rear 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, rearview cameras, available crash mitigating brakes, lane departure warning systems and blind spot warning systems.

The Panamera 4 E-Hybrid can drive on battery power alone for up to 14 miles. The CTS-V must run its internal combustion engine to move.

Regenerative brakes improve the Panamera’s fuel efficiency by converting inertia back into energy instead of wasting it (mild regeneration on non-hybrids). The CTS-V doesn’t offer a regenerative braking system.

In heavy traffic or at stoplights the Panamera’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The CTS-V doesn’t offer an automatic engine start/stop system.

The Panamera E Hybrid’s standard fuel tank has 2.1 gallons more fuel capacity than the CTS-V (21.1 vs. 19 gallons), for longer range between fill-ups. The Panamera’s standard fuel tank has 4.7 gallons more fuel capacity than the CTS-V (23.7 vs. 19 gallons).

The Panamera offers a standard sequential manual gearbox (PDK). With no clutch pedal to worry about and a fully automatic mode, a sequential manual gearbox is much more efficient than a conventional automatic but just as easy to drive. The CTS-V doesn’t offer a sequential manual gearbox or a conventional manual transmission.

The Panamera offers optional heat-treated ceramic brake rotors, which last ten to twenty times as long as conventional cast iron rotors, don’t rust, don’t fade during repeated high speed braking, and their lighter weight contribute to better braking, handling and acceleration. The CTS-V doesn’t offer ceramic brake rotors.

For better traction, the Panamera’s optional tires are larger than the largest tires available on the CTS-V (F:275/40R20 & R:315/35R20 vs. F:265/35R19 & R:295/30R19).

For better ride, handling and brake cooling the Panamera offers optional 21-inch wheels. The CTS-V’s largest wheels are only 19-inches.

The Panamera offers 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 CTS-V doesn’t offer an active sway bar system.

The Panamera 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 CTS-V.

The Panamera has a standard automatic load leveling suspension to keep ride height level with a heavy load or when towing. The CTS-V doesn’t offer a load leveling suspension.

For a smoother ride and more stable handling, the Panamera’s wheelbase is 1.5 inches longer than on the CTS-V (116.1 inches vs. 114.6 inches). The Panamera Executive’s wheelbase is 7.4 inches longer than on the CTS-V (122 inches vs. 114.6 inches).

For better handling and stability, the average track (width between the wheels) on the Panamera is 3.4 inches wider in the front and 3.5 inches wider in the rear than the track on the CTS-V.

The Panamera Turbo handles at 1.00 G’s, while the CTS-V pulls only .98 G’s of cornering force in a Car and Driver skidpad test.

For better maneuverability, the Panamera w/Rear Axle Steering’s turning circle is 2.9 feet tighter than the CTS-V’s (37.4 feet vs. 40.3 feet).

Because it has more passenger and cargo room, the EPA rates the Panamera 4dr Hatchback a Large car, while the CTS-V is rated a Mid-size.

The Panamera has 11 cubic feet more passenger volume than the CTS-V (108 vs. 97).

For enhanced passenger comfort on long trips the Panamera’s available rear seats recline. The CTS-V’s rear seats don’t recline.

The Panamera has a much larger trunk with its rear seat up than the CTS-V (17.6 vs. 13.7 cubic feet).

The Panamera Sport Turismo has a much larger trunk with its rear seat up than the CTS-V (18.3 vs. 13.7 cubic feet).

Pressing a switch automatically lowers the Panamera’s rear seats, to make changing between passengers and cargo easier. The CTS-V doesn’t offer automatic folding seats.

To make loading and unloading groceries and cargo easier, especially for short adults, the Panamera has a standard power liftgate, which opens and closes automatically by pressing a button, or optionally by just kicking your foot under the back bumper, completely leaving your hands free.

Unlike the driver-only memory system in the CTS-V, the Panamera offers an optional driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position, outside mirror angle, climate settings and radio stations and the front passenger seat also adjusts to the new passenger’s preset preferences.

The Panamera’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 CTS-V does not have an oil pressure gauge.

To improve rear visibility by keeping the rear window clear, the Panamera offers an optional rear wiper. The CTS-V doesn’t offer a rear wiper.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The Panamera offers available headlight washers to keep headlight output high. The CTS-V doesn’t offer headlight washers.

To help drivers avoid possible obstacles, the Panamera has standard cornering lights to illuminate around corners when the turn signals are activated. The CTS-V doesn’t offer cornering lights. The Panamera also offers optional adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle.

Optional air conditioned front and rear seats keep the Panamera’s passengers comfortable and take the sting out of hot leather in summer. The CTS-V doesn’t offer air-conditioned seats in the rear.

The Panamera offers optional massaging front and rear seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the CTS-V.

To keep a safe, consistent following distance, the Panamera offers an optional Adaptive Cruise Control, which alters the speed of the vehicle without driver intervention. This allows the driver to use cruise control more safely without constantly having to disengage it when approaching slower traffic. The CTS-V doesn’t offer an adaptive cruise control.
