Compare the2023 BMW M2 VS 2022 Porsche 911

The BMW M2 has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The 911 doesn’t offer knee airbags.

The M2 has standard Post-Crash Braking, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The 911 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 M2’s standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane. A lane departure warning system costs extra on the 911.

The M2 has a standard blind spot warning system which uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them and moves the vehicle back into its lane. A system to reveal vehicles in the 911’s blind spot costs extra.

To help make backing out of a parking space safer, the M2 has a standard rear cross-path warning system, which uses sensors in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. Rear cross-path warning costs extra on the 911.

The M2’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The 911 doesn’t offer a driver alert monitor.

Both the M2 and the 911 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 and rearview cameras.

BMW pays for scheduled maintenance on the M2 for 2 years and 26000 miles longer than Porsche pays for maintenance for the 911 (3/36,000 vs. 1/10,000).

There are over 80 percent more BMW dealers than there are Porsche dealers, which makes it much easier should you ever need service under the M2’s warranty.

J.D. Power and Associates’ 2022 Initial Quality Study of new car owners surveyed provide the statistics that show that BMW vehicles are better in initial quality than Porsche vehicles. J.D. Power ranks BMW above average in initial quality. With 35 more problems per 100 vehicles, Porsche is rated below average.

The M2’s 3.0 turbo 6-cylinder produces 74 more horsepower (453 vs. 379) and 75 lbs.-ft. more torque (406 vs. 331) than the 911’s standard 3.0 turbo 6-cylinder. The M2’s 3.0 turbo 6-cylinder produces 10 more horsepower (453 vs. 443) and 16 lbs.-ft. more torque (406 vs. 390) than the 911 S’ standard 3.0 turbo 6-cylinder.

On the EPA test cycle the M2 gets better mileage than the 911 Coupe:

			MPG
M2
RWD	Manual	3.0 turbo 6-cyl.	16 city/24 hwy
	Auto	3.0 turbo 6-cyl.	16 city/23 hwy
911 Coupe
RWD	Manual	4.0 DOHC flat-6	14 city/18 hwy
	Auto	4.0 DOHC flat-6	15 city/18 hwy
AWD	Auto	Turbo S 3.7 turbo flat-6	15 city/20 hwy
		Turbo 3.7 turbo flat-6	15 city/20 hwy

Regenerative brakes improve the M2’s fuel efficiency by converting inertia back into energy instead of wasting it. The 911 doesn’t offer a regenerative braking system.

For better stopping power the M2’s standard brake rotors are larger than those on the 911:

	M2	911
Front Rotors	15 inches	13 inches
Rear Rotors	14.6 inches	13 inches

For better traction, the M2 has larger front tires than the 911 (275/35R19 vs. 235/40R19). The M2’s front tires are larger than the largest tires available on the 911 (275/35R19 vs. 255/35R20).

The M2’s 275/35R19 front and 285/30R20 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 911’s standard 40 series front and 35 series rear tires.

For a smoother ride and more stable handling, the M2’s wheelbase is 11.6 inches longer than on the 911 (108.1 inches vs. 96.5 inches).

For better handling and stability, the track (width between the wheels) on the M2 is 1.1 inches wider in the front and 1.6 inches wider in the rear than the average track on the 911.

Because it has more passenger and cargo room, the EPA rates the M2 a Subcompact car, while the 911 Coupe is rated a Minicompact.

The M2 has 15 cubic feet more passenger volume than the 911 (88 vs. 73).

The M2 has .2 inches more front headroom, 3.3 inches more front shoulder room, 2.2 inches more rear headroom, 5 inches more rear legroom and 3.8 inches more rear shoulder room than the 911.

The M2 has a much larger trunk than the 911 Coupe with its rear seat up (10 vs. 4.6 cubic feet).

With its coupe body style, valet key, locking rear seatbacks and remote trunk release lockout, the M2 offers cargo security. The 911’s non-lockable folding seat defeats cargo security.

The M2 Auto offers a remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The 911 doesn’t offer a remote starting system.

The M2 offers an optional heads-up display that projects speed and tachometer readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The 911 doesn’t offer a heads-up display.

If the windows are left open on the M2 the driver can close them all at the outside door handle. On a hot day the driver can lower the windows from a distance using the keyless remote. The driver of the 911 can only operate the windows from inside the vehicle, with the ignition on.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the BMW M2 offers an optional wireless phone charging system (Qi) in the center console. The 911 doesn’t offer wireless personal charging.

The BMW 2 Series outsold the Porsche 911 by 15% during the 2022 model year.
