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 570S 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 570S 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 offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The 570S doesn’t offer all-wheel drive.

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 570S 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 570S 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 570S have standard driver and passenger frontal airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights and rearview cameras.

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 570S’ 3-year basic warranty expires 1 year sooner.

The 911’s corrosion warranty is 7 years longer than the 570S’ (12 vs. 5 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.

Engine

The 911 GT2 RS’ standard 3.8 turbo 6 cyl. produces 138 more horsepower (700 vs. 562) and 110 lbs.-ft. more torque (553 vs. 443) than the 570S’ 3.8 turbo V8.

In a Motor Trend race course test, the Porsche 911 Turbo S Coupe was clocked 1.66 seconds faster than the McLaren 570GT (93.21 sec. vs. 94.87 sec.).

The flat cylinder configuration of the boxer engine in the 911 lowers its center of gravity, enhancing handling stability. The 570S doesn’t offer a boxer engine configuration.

Fuel Economy and Range

On the EPA test cycle the 911 Coupe RWD Auto with its standard engine gets better fuel mileage than the 570S Auto (22 city/30 hwy vs. 16 city/23 hwy).

Regenerative brakes improve the 911’s fuel efficiency by converting inertia back into energy instead of wasting it. The 570S doesn’t offer a regenerative braking system.

The 911 GT2 RS’ optional fuel tank has 4.7 gallons more fuel capacity than the 570S (23.7 vs. 19 gallons).

Drivetrain

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 570S is not available with all-wheel drive.

Brakes and Stopping

For better stopping power the 911’s front brake rotors are larger than those on the 570S:

570S

Front Rotors

16.1 inches

15.5 inches

Rear Rotors

15.4 inches

15 inches

The 911 stops much shorter than the 570S:

Tires and Wheels

For better traction, the 911 has larger standard tires than the 570S (F:235/40R19 & R:295/35R19 vs. F:225/35R19 & R:285/35R20). The 911 GT2 RS/GT3 RS’ tires are larger than the largest tires available on the 570S (F:265/35R20 & R:325/30R21 vs. F:225/35R19 & R:285/35R20).

The 911’s optional 305/30R20 rear tires provide better handling because they have a lower 30 series profile (height to width ratio) that provides a stiffer sidewall than the 570S’ 35 series tires.

For better ride, handling and brake cooling the 911 GT2 RS/GT3 RS has standard 20-inch front and 21-inch rear wheels. The 570S’ largest wheels are only 19-inches in the front and 20-inches in the rear.

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 570S doesn’t offer an active sway bar system.

The 911 GT2 RS handles at 1.17 G’s, while the 570GT pulls only 1.03 G’s of cornering force in a Motor Trend skidpad test.

The 911 GT2 RS executes Motor Trend’s “Figure Eight” maneuver 1.3 seconds quicker than the 570GT (21.9 seconds @ 1.03 average G’s vs. 23.2 seconds @ .94 average G’s).

For better maneuverability, the 911 GT2 RS’ turning circle is 7.4 feet tighter than the 570S’ (33.6 feet vs. 41 feet). The 911’s turning circle is 4.6 feet tighter than the 570S’ (36.4 feet vs. 41 feet).

Chassis

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 570S doesn’t offer active grille shutters.

As tested by Car and Driver, the interior of the 911 Turbo S Coupe is quieter than the 570S Coupe:

 

911

570S

At idle

61 dB

63 dB

Full-Throttle

82 dB

97 dB

70 MPH Cruising

74 dB

74 dB

Passenger Space

The 911 has standard seating for 4 passengers; the 570S can only carry 2.

The 911 Coupe has 21 cubic feet more passenger volume than the 570S (70 vs. 49).

Ergonomics

The 911’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 570S does not have an oil pressure gauge.

To improve rear visibility by keeping the rear window clear, the 911 offers an optional rear wiper. The 570S 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 570S 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 570S 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 570S doesn’t offer cornering lights.

The 911’s sun-visors swivel front-to-side to block glare from the side windows. The 570S’ visors are fixed into the windshield header.

The 911’s power mirror controls are mounted on the armrest for easy access. The 570S’ power mirror controls are on the dash, hidden behind the steering wheel, where they are awkward to manipulate.

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 570S 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 570S 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 570S 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 570S doesn’t offer an adaptive cruise control.

To help keep the driver’s hands on the wheel, the 911 offers optional steering wheel controls for the radio. The 570S doesn’t offer steering wheel audio controls.
