Safety

Both the Panamera and Q70 have child safety locks to prevent children from opening the rear doors. The Panamera offers optional 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 Q70’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.

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 Q70 doesn’t offer a night vision system.

Both the Panamera and the Q70 have standard driver and passenger frontal airbags, front side-impact 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, blind spot warning systems and around view monitors.

Warranty

The Panamera’s corrosion warranty is 5 years longer than the Q70’s (12 vs. 7 years).

Reliability

The battery on the Panamera is in the trunk, which protects it from hot underhood temperatures that can degrade battery life. By keeping the Panamera’s battery 20 to 30 degrees cooler, its life is increased by years. The Q70’s battery is in the hot engine compartment.

J.D. Power and Associates’ 2018 Initial Quality Study of new car owners surveyed provide the statistics that show that Porsche vehicles are better in initial quality than Infiniti vehicles. J.D. Power ranks Porsche fourth in initial quality, above the industry average. With 13 more problems per 100 vehicles, Infiniti is ranked 14th.

J.D. Power and Associates’ 2018 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Porsche vehicles are more reliable than Infiniti vehicles. J.D. Power ranks Porsche second in reliability, above the industry average. With 20 more problems per 100 vehicles, Infiniti is ranked fourth.

The Panamera 4 E-Hybrid can drive on battery power alone for up to 31 miles. The Q70 must run its internal combustion engine to move.

An engine control system that can shut down half of the engine’s cylinders helps improve the Panamera Turbo’s fuel efficiency. The Q70 doesn’t offer a system that can shut down part of the engine.

Regenerative brakes improve the Panamera’s fuel efficiency by converting inertia back into energy instead of wasting it. The Q70 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 Q70 doesn’t offer an automatic engine start/stop system.

The Panamera E Hybrid’s standard fuel tank has 1.1 gallons more fuel capacity than the Q70 (21.1 vs. 20 gallons), for longer range between fill-ups. The Panamera’s standard fuel tank has 3.7 gallons more fuel capacity than the Q70 (23.7 vs. 20 gallons).

Transmission

An eight-speed automatic (SMG) is standard on the Porsche Panamera, for better acceleration and lower engine speed on the highway. Only a seven-speed automatic is available for the Q70.

The Panamera offers a standard sequential manual gearbox (SMG). With no clutch pedal to worry about and a fully automatic mode, an SMG is much more efficient than a conventional automatic but just as easy to drive. The Q70 doesn’t offer an SMG or a conventional manual transmission.

The Panamera’s optional launch control uses engine electronics to hold engine RPM’s precisely in order to provide the most stable and rapid acceleration possible, using all of the available traction. The Q70 doesn’t offer launch control.

Brakes and Stopping

For better stopping power the Panamera’s brake rotors are larger than those on the Q70:

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 Q70 doesn’t offer ceramic brake rotors.

The Panamera stops much shorter than the Q70:

Tires and Wheels

For better traction, the Panamera has larger standard tires than the Q70 (F:265/45R19 & R:295/40R19 vs. 245/40R20). The Panamera’s optional tires are larger than the largest tires available on the Q70 (F:275/40R20 & R:315/35R20 vs. 245/40R20).

The Panamera’s standard 265/45R19 front and 295/40R19 rear tires provide better handling because they have a lower 45 series front and 40 series rear profile (height to width ratio) that provides a stiffer sidewall than the Q70’s standard 50 series tires. The Panamera’s optional 275/35R21 front and 315/30R21 rear tires have a lower 35 series front and 30 series rear profile than the Q70’s optional 40 series tires.

For better ride, handling and brake cooling the Panamera has standard 19-inch wheels. Smaller 18-inch wheels are standard on the Q70. The Panamera’s optional 21-inch wheels are larger than the 20-inch wheels optional on the Q70.

Suspension and Handling

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 Q70 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. Infiniti doesn’t offer an active suspension on the Q70.

The Panamera offers an available 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 Q70’s suspension doesn’t offer adjustable shock absorbers.

The Panamera has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The Panamera’s height leveling suspension allows the driver to raise ride height for better off-road clearance and then lower it again for easier entering and exiting and better on-road handling. The Q70 doesn’t offer a load leveling suspension.

For a smoother ride and more stable handling, the Panamera’s wheelbase is longer than on the Q70:

116.1 inches

114.2 inches

LWB 4dr Hatchback

120.1 inches

For better handling and stability, the average track (width between the wheels) on the Panamera is 3.5 inches wider in the front and 3 inches wider in the rear than the average track on the Q70.

The Panamera Turbo handles at 1.00 G’s, while the Q70 3.7 LUXE pulls only .82 G’s of cornering force in a Car and Driver skidpad test.

The Panamera Turbo executes Motor Trend’s “Figure Eight” maneuver 2.8 seconds quicker than the Q70 5.6 LUXE AWD (23.9 seconds @ .86 average G’s vs. 26.7 seconds @ .67 average G’s).

Chassis

The front grille of the Panamera uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The Q70 doesn’t offer active grille shutters.

As tested by Car and Driver, the interior of the Panamera Turbo is quieter than the Q70 3.7 LUXE:

Passenger Space

Because it has more passenger and cargo room, the EPA rates the Panamera 4dr Hatchback a Large car, while the Q70 is rated a Mid-size.

The Panamera has 4.4 cubic feet more passenger volume than the Q70 (108 vs. 103.6).

For enhanced passenger comfort on long trips the Panamera’s available rear seats recline. The Q70’s rear seats don’t recline.

Cargo Capacity

The Panamera has a much larger trunk with its rear seat up than the Q70 (17.6 vs. 14.9 cubic feet).

The Panamera 4dr Hatchback has a much larger trunk with its rear seat up than the Q70 (18.3 vs. 14.9 cubic feet).

The Panamera’s available rear seats fold to accommodate long and bulky cargo. The Q70 doesn’t offer folding rear seats, only a ski pass-through.

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. The Q70 doesn’t offer a power trunk.

Ergonomics

Unlike the driver-only memory system in the Q70, 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 Q70 does not have an oil pressure gauge.

The power windows standard on both the Panamera and the Q70 have locks to prevent small children from operating them. When the lock on the Panamera is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The Q70 prevents the driver from operating the other windows just as it does the other passengers.

The Panamera’s front and rear power windows all open or close fully with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside the car. The Q70’s rear power window switches have to be held the entire time to open or close them fully.

To improve rear visibility by keeping the rear window clear, the Panamera offers an optional rear wiper. The Q70 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 Q70 doesn’t offer headlight washers.

While driving with high beams on, sensitive light sensors available for the Panamera detect other vehicles which could be blinded and automatically switch to low beams. The Q70 doesn’t offer automatic dimming high beams.

Optional air conditioned front and rear seats keep the Panamera’s passengers comfortable and take the sting out of hot leather in summer. The Q70 doesn’t offer air-conditioned seats in the rear.

Standard Connect Plus for the Panamera allows the driver and passengers access to select programs on their smartphones, including reading text messages aloud, playing internet radio stations, finding fuel prices at nearby service stations, searching the internet, following twitter accounts and other connected activities without taking their eyes off the road or their hands from the wheel. The Q70 doesn’t offer factory integrated smartphone program access.

The Panamera 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 Q70 doesn’t offer a house-current electrical outlet.

Model Availability

The Porsche Panamera comes in four door hatchback and station wagon bodystyles; the Infiniti Q70 isn’t available as a station wagon.

Recommendations

The Porsche Panamera outsold the Infiniti Q70 by 80% during 2018.
