Safety Comparison

The M4 offers optional City Collision Mitigation, 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 S5 doesn't offer collision warning or crash mitigation brakes.

The M4’s optional lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane. The S5 doesn’t offer a lane departure warning system.

The M4 offers an optional Side and Top View Cameras to allow the driver to see objects all around the vehicle on a screen. The S5 only offers a rear monitor and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the front or sides.

The M4 has standard BMW Assist, 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 S5 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 M4 and the S5 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 and electronic stability systems to prevent skidding.

Warranty Comparison

BMW pays for scheduled maintenance on the M4 for 4 years and 50,000 miles. BMW will pay for oil changes, lubrication and any other required maintenance. Audi only pays for the first scheduled maintenance visit on the S5.

There are over 33 percent more BMW dealers than there are Audi dealers, which makes it easier should you ever need service under the M4’s warranty.

Reliability Comparison

To reliably power the ignition and other systems and to recharge the battery, the M4 has a standard 209-amp alternator. The S5’s 150-amp alternator isn’t as powerful.

J.D. Power and Associates’ 2014 Initial Quality Study of new car owners surveyed provide the statistics that show that BMW vehicles are better in initial quality than Audi vehicles. J.D. Power ranks BMW 8th in initial quality, above the industry average. With 3 more problems per 100 vehicles, Audi is ranked 11th.

J.D. Power and Associates’ 2014 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that BMW vehicles are more reliable than Audi vehicles. J.D. Power ranks BMW 11th in reliability. With 21 more problems per 100 vehicles, Audi is ranked 19th.

Engine Comparison

The M4’s 3.0 turbo 6 cyl. produces 92 more horsepower (425 vs. 333) and 81 lbs.-ft. more torque (406 vs. 325) than the S5’s 3.0 supercharged V6.

Fuel Economy and Range Comparison

In heavy traffic or at stoplights the M4’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The S5 doesn’t offer an automatic engine start/stop system.

The M4 offers optional heat-treated ceramic brake rotors, which last ten to twenty times as long as conventional cast iron rotors, don’t rust, don’t fade during repeated high speed braking, and their lighter weight contribute to better braking, handling and acceleration. The S5 doesn’t offer ceramic brake rotors.

The M4 stops much shorter than the S5:

Tires and Wheels Comparison

For better traction, the M4 has larger tires than the S5 (F:255/40R18 & R:275/40R18 vs. 245/40R18).

Suspension and Handling Comparison

For a smoother ride and more stable handling, the M4’s wheelbase is 2.4 inches longer than on the S5 (110.7 inches vs. 108.3 inches).

For better handling and stability, the track (width between the wheels) on the M4 is 1.1 inches wider in the rear than on the S5.

The M4’s front to rear weight distribution is more even (51.8% to 48.2%) than the S5’s (55.7% to 44.3%). This gives the M4 more stable handling and braking.

The M4 Coupe handles at 1.01 G’s, while the S5 Coupe pulls only .90 G’s of cornering force in a Motor Trend skidpad test.

The M4 Coupe executes Motor Trend’s “Figure Eight” maneuver 1.4 seconds quicker than the S5 Coupe (24.2 seconds @ .84 average G’s vs. 25.6 seconds @ .71 average G’s).

Chassis Comparison

The BMW M4 may be more efficient, handle and accelerate better because it weighs about 350 to 750 pounds less than the Audi S5.

The M4’s standard power retractable hardtop allows a seamless transition from an open car, to a completely sealed coupe. The S5 doesn’t offer a retractable hardtop.

Passenger Space Comparison

Because it has more passenger and cargo room, the M4 Coupe is rated a Compact car by the EPA, while the S5 Coupe is rated a Subcompact.

The M4 Coupe has 6 cubic feet more passenger volume than the S5 Coupe (90 vs. 84). The M4 Convertible has 10 cubic feet more passenger volume than the S5 Cabriolet (91 vs. 81).

The M4 Coupe has 2.2 inches more front headroom, .9 inches more front legroom, 1 inch more front shoulder room, .1 inches more rear headroom and 2 inches more rear legroom than the S5 Coupe.

The M4 Convertible has .4 inches more front headroom, .9 inches more front legroom, 1 inch more front shoulder room, .8 inches more rear headroom, 1.2 inches more rear legroom and 3 inches more rear shoulder room than the S5 Cabriolet.

Cargo Capacity Comparison

To make loading groceries and cargo easier when your hands are full, the M4’s available trunk can be opened just by kicking your foot under the back bumper, leaving your hands completely free. The S5 doesn’t offer a hands-free gesture to open its trunk, forcing you to put cargo down if your hands are full.

Ergonomics Comparison

The M4 offers an optional heads-up display which projects speed and other key instrumentation readouts onto the windshield, allowing drivers to view information without diverting their eyes from the road. The S5 doesn’t offer a heads-up display.

If the front windows are left down on the M4 w/Comfort Access the driver can raise them using the key in the outside lock cylinder. On a hot day the driver can lower the windows from outside the vehicle using the key in the outside lock cylinder or the keyless remote. The driver of the S5 can’t use the remote to operate the windows.

Comfort Access optional on the M4 allows you to unlock the driver’s door, trunk and start the engine all without removing a key from pocket or purse. This eliminates searching for keys before loading groceries, getting in the vehicle in bad weather or making a hurried start to your trip. The Audi S5’s Audi Advanced Key doesn’t unlock the trunk.

While driving with high beams on, sensitive light sensors available for the M4 detect other vehicles which could be blinded and automatically switch to low beams. The S5 doesn’t offer automatic dimming high beams.

When the M4 is put in reverse, the passenger rearview mirror tilts from its original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirror into its original position. The S5’s mirror doesn’t automatically adjust for backing.

On extremely cold Winter days, the M4’s optional heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the car heater warms up. The S5 doesn’t offer a heated steering wheel.

Standard BMW Apps for the M4 allows the driver and passengers access to select programs on their smartphones, including reading text messages aloud, playing internet radio stations, tagging songs to buy them later, following twitter accounts and other connected activities without taking their eyes off the road or their hands from the wheel. The S5 doesn’t offer factory integrated smartphone program access.

The M4’s optional Parking Assistant can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The S5 doesn’t offer an automated parking system.
