The 911 (except GT3) has standard Warn and Brake Assist, 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 812 doesn't offer collision warning or crash mitigation brakes.

The 911 offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The 812 doesn’t offer all-wheel drive.

A passive infrared night vision system optional on the 911 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. The 812 doesn’t offer a night vision system.

The 911’s optional 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. The 812 doesn’t offer a lane departure warning system.

The 911 offers an optional Surround View to allow the driver to see objects all around the vehicle on a screen. The 812 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.

To help make backing out of a parking space safer, the 911’s optional rear cross-path warning system uses sensors in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The 812 doesn’t offer a cross-path warning system.

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 812 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 812 have standard driver and passenger frontal airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rear parking sensors and available blind spot warning systems.

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 812’s 3-year basic warranty expires 1 year sooner.

The 911’s corrosion warranty is 9 years longer than the 812’s (12 vs. 3 years).

There are over 4 times as many Porsche dealers as there are Ferrari dealers, which makes it much easier should you ever need service under the 911’s warranty.

Engine

The 911 Turbo S’ 3.7 turbo 6-cylinder produces 80 lbs.-ft. more torque (590 vs. 510) than the 812 Competizione’s optional 6.5 DOHC V12.

As tested in Motor Trend the 911 GT3 4.0 DOHC 6-cylinder is faster than the Ferrari 812 (base engine) (automatics tested):

	911	812
Zero to 60 MPH	2.7 sec	2.8 sec

The flat cylinder configuration of the boxer engine in the 911 lowers its center of gravity, enhancing handling stability. The 812 doesn’t offer a boxer engine configuration.

Transmission and Drivetrain

An eight-speed automatic (SMG) is standard on the Porsche 911, for better acceleration and lower engine speed on the highway. Only a seven-speed automatic is available for the 812.

All wheel drive, available in the 911, provides the best traction for acceleration in wet, dry, and icy conditions. In corners, all wheel drive allows both outside wheels to provide power, balancing the car. This allows for better handling. The Ferrari 812 is not available with all wheel drive.

Brakes and Stopping

For better stopping power the 911 Turbo S/Sport Classic’s front brake rotors are larger than those on the 812:

	911 Turbo S/Sport Classic	812
Front Rotors	16.5 inches	15.7 inches
Rear Rotors	15.4 inches	14.2 inches

The 911 stops much shorter than the 812:

	911	812
60 to 0 MPH	93 feet	99 feet	Motor Trend

Tires and Wheels

The 911’s optional 305/30R21 rear tires provide better handling because they have a lower 30 series profile (height to width ratio) that provides a stiffer sidewall than the 812’s 35 series tires.

For better ride, handling and brake cooling the 911 offers optional 21-inch rear wheels. The 812’s largest wheels are only 20-inches.

Suspension and Handling

The 911 (except Base/GT3) 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 812 doesn’t offer an active sway bar system.

The 911 GT3 handles at 1.15 G’s, while the 812 Coupe pulls only 1.03 G’s of cornering force in a Motor Trend skidpad test.

The 911 GT3 executes Motor Trend’s “Figure Eight” maneuver 1 seconds quicker than the 812 Coupe (22.3 seconds @ .95 average G’s vs. 23.3 seconds @ .93 average G’s).

For better maneuverability, the 911 GT3’s turning circle is 7 feet tighter than the 812’s (34.1 feet vs. 41.1 feet). The 911’s turning circle is 4.3 feet tighter than the 812’s (36.8 feet vs. 41.1 feet).

Chassis

The 911 is shorter than the 812, making the 911 easier to handle, maneuver and park in tight spaces:

	911	812
2dr Hatchback	177.9 inches	183.3 inches
Convertible	177.9 inches	184.8 inches

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 812 doesn’t offer active grille shutters.

Passenger Space

The 911 has standard seating for 4 passengers; the 812 can only carry 2.

Ergonomics

The 911’s front and rear power windows all open or close with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside of the car. The 812’s passenger windows don’t close automatically.

The 911’s standard power window controls are mounted on the armrest for easy access. The 812’s available power window controls are spread out on the center console where they can’t be seen without the driver completely removing his eyes from the road.

Comfort Access standard on the 911 (except GT3) allows you to unlock the driver’s door, trunk and start the engine all without removing a key from pocket or purse. This eliminates searching for keys before loading groceries, getting in the vehicle in bad weather or making a hurried start to your trip. The Ferrari 812’s Keyless Start doesn’t unlock the doors or the trunk.

To improve rear visibility by keeping the rear window clear, the 911 (except Cabriolet/GT3) offers an optional rear wiper. The 812 doesn’t offer a rear wiper.

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 812 doesn’t offer automatic dimming high beams.

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 812 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 812 doesn’t offer a heated steering wheel.

To keep a safe, consistent following distance, the 911 (except Manual) 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 812 doesn’t offer an adaptive cruise control.

The 911’s standard separate stalk mounted cruise control on/off switch is conveniently located with the rest of the cruise controls. The 812’s standard cruise control must be turned on with a hard to find switch on the dashboard.

The 911 (except Manual/GT3)’s optional Active Parking Support can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. Remote ParkAssist will park and retrieve your car remotely: press a button and watch it park itself. This is ideal for tight locations. The 812 doesn’t offer an automated parking system.

Recommendations

J.D. Power and Associates rated the 911 first among premium sporty cars in owner reported satisfaction. This includes how well the vehicle performs and satisfies its owner’s expectations. The 812 isn’t in the top three.
