Safety

The 911 offers optional Porsche Active Safe, which use forward mounted sensors to warn the driver of a possible collision ahead. If the driver doesn’t react and the system determines a collision is imminent, it automatically applies the brakes at full-force in order to reduce the force of the crash or avoid it altogether. The GT-R doesn't offer collision warning or crash mitigation brakes.

The 911 has a standard automatic post-collision braking system, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The GT-R doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

The 911’s optional blind spot warning system uses digital cameras monitored by computer to alert the driver to moving objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. The GT-R doesn’t offer a system to reveal objects in the driver’s blind spots.

The 911 has standard Porsche Connect, which uses a global positioning satellite (GPS) receiver and a cellular system to 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 GT-R 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 911 and the GT-R have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras and available all-wheel drive.

Warranty

The 911 comes with a full 4-year/50,000-mile basic warranty, which covers the entire car and includes 24-hour roadside assistance. The GT-R’s 3-year/36,000-mile basic warranty expires 1 year and 14,000 miles sooner.

The 911’s corrosion warranty is 7 years longer than the GT-R’s (12 vs. 5 years).

Reliability

To reliably power the ignition and other systems and to recharge the battery, the 911 has a standard 204-amp alternator (245-amp - 911 S and 175 Turbo). The GT-R’s 150-amp alternator isn’t as powerful.

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 Nissan vehicles. J.D. Power ranks Porsche fourth in initial quality, above the industry average. With 6 more problems per 100 vehicles, Nissan is ranked 10th.

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 Nissan vehicles. J.D. Power ranks Porsche second in reliability, above the industry average. With 33 more problems per 100 vehicles, Nissan is ranked 10th.

From surveys of all its subscribers, Consumer Reports’ December 2018 Auto Issue reports that Porsche vehicles are more reliable than Nissan vehicles. Consumer Reports ranks Porsche 3 places higher in reliability than Nissan.

Engine

The 911 GT2 RS’ 3.8 turbo 6 cyl. produces 100 more horsepower (700 vs. 600) and 72 lbs.-ft. more torque (553 vs. 481) than the GT-R NISMO’s optional 3.8 turbo V6.

In a Motor Trend race course test, the Porsche 911 Turbo S Coupe was clocked 1.8 seconds faster than the Nissan GT-R NISMO (93.21 sec. vs. 95.01 sec.).

The flat cylinder configuration of the boxer engine in the 911 lowers its center of gravity, enhancing handling stability. The GT-R doesn’t offer a boxer engine configuration.

Fuel Economy and Range

On the EPA test cycle the 911 Coupe Carrera 4 Auto with its standard engine gets better fuel mileage than the GT-R Auto with its standard engine (22 city/28 hwy vs. 16 city/22 hwy).

Regenerative brakes improve the 911’s fuel efficiency by converting inertia back into energy instead of wasting it. The GT-R doesn’t offer a regenerative braking system.

In heavy traffic or at stoplights the 911’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 GT-R doesn’t offer an automatic engine start/stop system.

The 911 GT2 RS’ optional fuel tank has 4.2 gallons more fuel capacity than the GT-R (23.7 vs. 19.5 gallons).

Transmission

A seven-speed automatic (SMG) is available on the Porsche 911, for better acceleration and lower engine speed on the highway. Only a six-speed automatic is available for the GT-R.

Brakes and Stopping

For better stopping power the 911’s front brake rotors are larger than those on the GT-R:

GT-R

Front Rotors

16.1 inches

15.35 inches

Rear Rotors

15.4 inches

15 inches

The 911 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 GT-R doesn’t offer ceramic brake rotors.

The 911 stops shorter than the GT-R:

Tires and Wheels

For better traction, the 911 GT2 RS/GT3 RS’ tires are larger than the largest tires available on the GT-R (F:265/35R20 & R:325/30R21 vs. F:255/40R20 & R:285/35R20).

The 911’s optional 245/35R20 front and 305/30R20 rear tires provide better handling because they have a lower 35 series front and 30 series rear profile (height to width ratio) that provides a stiffer sidewall than the GT-R’s 40 series front and 35 series rear tires.

For better ride, handling and brake cooling the 911 GT2 RS/GT3 RS has standard 21-inch rear wheels. The GT-R’s largest wheels are only 20-inches.

Suspension and Handling

The 911 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 GT-R doesn’t offer an active sway bar system.

The 911 has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The GT-R doesn’t offer a load leveling suspension.

The 911 GT2 RS handles at 1.17 G’s, while the GT-R Premium pulls only .98 G’s of cornering force in a Motor Trend skidpad test.

The 911 GT2 RS executes Motor Trend’s “Figure Eight” maneuver 1.7 seconds quicker than the GT-R Premium (21.9 seconds @ 1.03 average G’s vs. 23.6 seconds @ .79 average G’s).

For better maneuverability, the 911 GT2 RS’ turning circle is 3 feet tighter than the GT-R’s (33.6 feet vs. 36.6 feet). The 911’s turning circle is .2 feet tighter than the GT-R’s (36.4 feet vs. 36.6 feet).

Chassis

The Porsche 911 may be more efficient, handle and accelerate better because it weighs about 250 to 800 pounds less than the Nissan GT-R.

The 911 is 7.5 inches shorter than the GT-R, making the 911 easier to handle, maneuver and park in tight spaces.

The front grille of the 911 uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The GT-R doesn’t offer active grille shutters.

Cargo Capacity

The 911’s standard rear seats fold to accommodate long and bulky cargo. The GT-R doesn’t offer folding rear seats.

Servicing Ease

The 911 uses gas struts to support the hood for easier service access. The GT-R uses a prop rod to support its heavy hood. It takes two hands to open the hood and set the prop rod, the prop rod gets in the way during maintenance and service, and the prop rod could be knocked out, causing the heavy hood to fall on the person maintaining or servicing the car.

J.D. Power and Associates surveys of service recipients show that Porsche service is better than Nissan. J.D. Power ranks Porsche second in service department satisfaction. With a 50% lower rating, Nissan is ranked 20th.

Ergonomics

When three different drivers share the 911, the optional memory system makes it convenient for all three. Each keyless remote activates different, customized memories for the driver’s seat position, steering wheel position, outside mirror angle and climate settings. The GT-R doesn’t offer a memory system.

The 911’s optional easy entry system raises the steering wheel and glides the driver’s seat back when the door is unlocked or the ignition is switched off, making it easier for the driver to get in and out. The GT-R doesn’t offer an easy entry system.

The 911’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The GT-R’s intermittent wipers change speed with vehicle speed, but can’t turn on and off or change speed based on changing rainfall.

To improve rear visibility by keeping the rear window clear, the 911 offers an optional rear wiper. The GT-R 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 911 offers available headlight washers to keep headlight output high. The GT-R doesn’t offer headlight washers.

While driving with high beams on, sensitive light sensors available for the 911 detect other vehicles which could be blinded and automatically switch to low beams. The GT-R doesn’t offer automatic dimming high beams.

To help drivers see further while navigating curves, the 911 offers optional adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The GT-R doesn’t offer cornering lights.

The 911’s power mirror controls are mounted on the armrest for easy access. The GT-R’s power mirror controls are on the dash, hidden behind the steering wheel, where they are awkward to manipulate.

When the 911 is put in reverse, the passenger rearview mirror tilts from its original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirror into its original position. The GT-R’s mirror doesn’t automatically adjust for backing.

The 911 offers optional automatic dimming rear and side view mirrors which automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The GT-R has an automatic rear view mirror, but its side mirrors don’t dim.

Optional air-conditioned seats in the 911 keep the driver and front passenger comfortable and take the sting out of hot seats in summer. The GT-R doesn’t offer air-conditioned seats.

On extremely cold winter days, the 911’s optional heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the car heater warms up. The GT-R doesn’t offer a heated steering wheel.

To keep a safe, consistent following distance, the 911 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 GT-R doesn’t offer an adaptive cruise control.

Model Availability

The Porsche 911 comes in coupe and convertible bodystyles; the Nissan GT-R isn’t available as a convertible.

The 911 is available in both rear-wheel drive and all-wheel drive configurations. The GT-R doesn’t offer a two-wheel drive configuration.
