The 911 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 720S 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 720S 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 720S 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 720S doesn’t offer a lane departure 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 720S 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 720S 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, rearview cameras and available around view monitors.

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 720S’ 3-year basic warranty expires 1 year sooner.

The 911’s corrosion warranty is 2 years longer than the 720S’ (12 vs. 10 years).

There are almost 10 times as many Porsche dealers as there are McLaren dealers, which makes it much easier should you ever need service under the 911’s warranty.

An eight-speed automatic (SMG) is available on the Porsche 911, for better acceleration and lower engine speed on the highway. Only a seven-speed automatic is available for the 720S.

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 McLaren 720S is not available with all wheel drive.

The 911 S 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 720S doesn’t offer an active sway bar system.

For better maneuverability, the 911’s turning circle is 3.2 feet tighter than the 720S’ (36.8 feet vs. 40 feet).

To improve rear visibility by keeping the rear window clear, the 911 offers an optional rear wiper. The 720S 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 720S doesn’t offer automatic dimming high beams.

The 911’s sun-visors swivel front-to-side to block glare from the side windows. The 720S’ visors are fixed into the windshield header.

The 911’s power mirror controls are mounted on the armrest for easy access. The 720S’ power mirror controls are on the dash where they are possibly hidden by the steering wheel and are awkward to manipulate.

The 911 has standard 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 720S 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 720S 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 720S 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.

To help keep the driver’s hands on the wheel, the 911 has standard steering wheel controls for the radio. The 720S doesn’t offer steering wheel audio controls.
