The M4’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The 718 Boxster doesn’t offer pre-crash pretensioners.

The M4’s standard pretensioning seatbelts also sense rear collisions and remove slack from the front seatbelts to help protect the occupants from whiplash and other injuries. The 718 Boxster doesn’t offer a whiplash protection system.

The M4 has a standard PostCrash iBrake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The 718 Boxster 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.

Over 200 people are killed each year when backed over by motor vehicles. The M4 offers an optional Active Park Distance Control that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The 718 Boxster doesn’t offer backup collision prevention brakes.

The M4 offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The 718 Boxster doesn’t offer all-wheel drive.

The M4’s 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 718 Boxster doesn’t offer a lane departure warning system.

The M4 offers an optional Surround View to allow the driver to see objects all around the vehicle on a screen. The 718 Boxster only offers a rear monitor and front and rear parking sensors that beep. That doesn’t help with obstacles to the sides.

The M4 has a standard blind spot warning system that 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 718 Boxster’s blind spot costs extra.

To help make backing out of a parking space safer, the M4’s standard Cross Traffic Warning uses sensors in the rear to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The 718 Boxster doesn’t offer a rear cross-path warning system.

The M4’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 718 Boxster doesn’t offer a driver alert monitor.

Both the M4 and the 718 Boxster have standard driver and passenger frontal airbags, front side-impact 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.

The BMW M4 weighs 605 to 1286 pounds more than the Porsche 718 Boxster. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.

BMW pays for scheduled maintenance on the M4 for 2 years and 26000 miles longer than Porsche pays for maintenance for the 718 Boxster (3/36,000 vs. 1/10,000).

There are over 76 percent more BMW dealers than there are Porsche dealers, which makes it much easier should you ever need service under the M4’s warranty.

To reliably power the ignition and other systems and to recharge the battery, the M4 has a standard 209-amp alternator. The 718 Boxster’s 175-amp alternator isn’t as powerful.

To reliably start during all conditions and help handle large electrical loads, the M4 has a standard 900-amp battery. The 718 Boxster’s 450-amp battery isn’t as powerful.

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the BMW M4 higher (5 out of 10) than the Porsche 718 Boxster (1 to 5). This means the M4 produces up to 39 pounds less smog-producing pollutants than the 718 Boxster every 15,000 miles.

An eight-speed automatic is available on the BMW M4, for better acceleration and lower engine speed on the highway. Only a seven-speed automatic is available for the 718 Boxster.

All wheel drive, available in the M4, 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 Porsche 718 Boxster is not available with all wheel drive.

For better traction, the M4 has larger tires than the 718 Boxster (F:275/40R18 & R:285/35R19 vs. F:235/45R18 & R:265/45R18). The M4’s front tires are larger than the largest tires available on the 718 Boxster (275/40R18 vs. 245/35R20).

The M4’s standard 275/40R18 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 718 Boxster’s standard 45 series tires.

For better ride, handling and brake cooling the M4 has standard 19-inch rear wheels. Smaller 18-inch wheels are standard on the 718 Boxster.

For better handling and stability, the track (width between the wheels) on the M4 is 3.7 inches wider in the front and 2.8 inches wider in the rear than the average track on the 718 Boxster.

The M4 Convertible has a larger trunk with its top down than the 718 Boxster (10.6 vs. 9.6 cubic feet).

With its coupe body style, valet key, locking rear seatbacks and remote trunk release lockout, the M4 offers cargo security. The 718 Boxster’s non-lockable remote release defeats cargo security.

To make loading and unloading groceries and cargo easier, especially for short adults, the M4 offers an optional power trunk, which opens and closes automatically by pressing a button or just by kicking your foot under the back bumper, completely leaving your hands free. The 718 Boxster doesn’t offer a power trunk.

The M4 (except Manual) 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 718 Boxster doesn’t offer a remote starting system.

The M4 offers an optional heads-up display that projects speed, tachometer, warning and navigation instruction readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The 718 Boxster doesn’t offer a heads-up display.

If the windows are left open on the M4 the driver can close them all at the outside door handle or from a distance using the remote. On a hot day the driver can lower the windows from a distance using the keyless remote. The driver of the 718 Boxster can only operate the windows from inside the vehicle, with the ignition on.

The M4 has standard Comfort Access that allows you to unlock the doors from either outside door handle, open the trunk, and start the engine, all without removing the key from the pocket or purse. Porsche Entry and Drive costs extra on the 718 Boxster.

The M4’s power window, power lock, power mirror and cruise control switches are lit from behind, making them plainly visible and easier to operate at night. The 718 Boxster’s cruise control switches are unlit, making them difficult to find at night and operate safely.

The M4’s LED headlights produce a white, bright light using less electricity than the 718 Boxster’s standard xenon high intensity discharge (HID) headlights. HID headlights can be slow to reach full brightness or power cycle, causing issues when flashing them to signal other vehicles; LED headlights light instantly. LED lights also last about three to four times as long.

The M4’s sun-visors swivel front-to-side to block glare from the side windows. The 718 Boxster’s visors are fixed into the windshield header.

The BMW M4 has power folding mirrors that offer unparalleled convenience while maneuvering in tight places or parked. With the mirrors folded it’s easier to walk past and help prevent parking damage. The mirrors can be quickly unfolded when the driver is ready to leave. Power folding mirrors costs extra on the 718 Boxster.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the BMW M4 has a standard wireless phone charging system (Qi) in the front center console. The 718 Boxster doesn’t offer wireless personal charging.

The M4’s optional Parking Assistant Plus can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. The 718 Boxster doesn’t offer an automated parking system.
