Safety Comparison

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 6 Series doesn't offer collision warning or crash mitigation brakes.

Both the 911 and the 6 Series have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding and available all wheel drive.

Tires and Wheels Comparison

For better traction and acceleration, the 911 has larger standard rear tires than the 6 Series (285/35R19 vs. 245/45R18). The 911 4S/Turbo/GT3’s rear tires are larger than the largest rear tires available on the 6 Series (305/30R20 vs. 295/35R19).

The 911’s standard 235/40R19 front and 285/35R19 rear tires provide better handling because they have a lower 40 series front and 35 series rear profile (height to width ratio) that provides a stiffer sidewall than the 640i’s standard 45 series tires.

For better ride, handling and brake cooling the 911 has standard 19-inch wheels. Smaller 18-inch wheels are standard on the 640i.

Suspension and Handling Comparison

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 6 Series doesn’t offer an active sway bar system.

The 911 S Coupe handles at .99 G’s, while the 650i Coupe pulls only .94 G’s of cornering force in a Road & Track skidpad test.

The 911 S Cabriolet handles at 1.03 G’s, while the 650i Convertible pulls only .87 G’s of cornering force in a Motor Trend skidpad test.

The 911 S Coupe goes through Road & Track’s slalom 7.3 MPH faster than the 650i Coupe (74.1 vs. 66.8 MPH).

The 911 S Coupe Carrera 4 executes Motor Trend’s “Figure Eight” maneuver 1.4 seconds quicker than the 650i Coupe (23.9 seconds @ .85 average G’s vs. 25.3 seconds).

The 911 S Cabriolet executes Motor Trend’s “Figure Eight” maneuver 2.7 seconds quicker than the 650i Convertible (23.7 seconds @ .88 average G’s vs. 26.4 seconds @ .67 average G’s).

For better maneuverability, the 911 Turbo/GT3’s turning circle is 3.6 feet tighter than the 6 Series’ (34.8 feet vs. 38.4 feet). The 911’s turning circle is 2 feet tighter than the 6 Series’ (36.4 feet vs. 38.4 feet).

Chassis Comparison

The Porsche 911 may be more efficient, handle and accelerate better because it weighs about 950 to 1100 pounds less than the BMW 6 Series.

The 911 is 1 foot, 4 inches shorter than the 6 Series, making the 911 easier to handle, maneuver and park in tight spaces.

As tested by Car and Driver while at idle, the interior of the 911 S Cabriolet is quieter than the M6 Convertible (49 vs. 52 dB).

Cargo Capacity Comparison

The 911’s standard rear seats fold to accommodate long and bulky cargo. The 6 Series doesn’t offer folding rear seats, only a ski pass-through.

Ergonomics Comparison

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 6 Series has neither an oil pressure gauge nor a temperature gauge.

To improve rear visibility by keeping the rear window clear, the 911 offers an optional rear wiper. The 6 Series doesn’t offer a rear wiper.

Economic Advantages Comparison

The 911 will cost the buyer less in the long run because of its superior resale value. The Intellichoice estimates that the 911 will retain 48.46% to 55.08% of its original price after five years, while the 6 Series only retains 39.45% to 40.38%.

Recommendations Comparison

Intellichoice recognized the Porsche 911 as a “Best Overall Value of the Year” for the 2013 model year.

Motor Trend performed a comparison test in its November 2013 issue and they ranked the Porsche 911 S Coupe Carrera 4 first. They ranked the BMW M6 Coupe tenth.

J.D. Power and Associates rated the 911 second among midsize premium sporty cars in owner reported satisfaction. This includes how well the vehicle performs and satisfies its owner’s expectations. The 6 Series was rated third.

The 911 was chosen as one of Automobile Magazine’s “All Stars” for 6 of the last 18 years. The 6 Series hasn’t been picked since 2005.
