Safety Comparison

The M3 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 M3 and the S5 have standard driver and passenger frontal airbags, front side-impact 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 M3 for 3 years and 45000 miles longer than Audi pays for maintenance for the S5 (4/50,000 vs. 1/5000).

There are over 33 percent more BMW dealers than there are Audi dealers, which makes it easier should you ever need service under the M3’s warranty.

Reliability Comparison

To reliably power the ignition and other systems and to recharge the battery, the M3 has a standard 180 amp alternator. The S5’s 150 amp alternator isn’t as powerful.

J.D. Power and Associates’ 2012 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 10th in initial quality, above the industry average. With 8 more problems per 100 vehicles, Audi is ranked 16th, below the industry average.

The M3’s 4.0 DOHC V8 produces 81 more horsepower (414 vs. 333) than the S5’s 3.0 supercharged V6.

The M3 Coupe has .5 inches more front legroom, 3.1 inches more front shoulder room, .8 inches more rear headroom, 2 inches more rear legroom and 2.4 inches more rear shoulder room than the S5 Coupe.

The M3 Convertible has .5 inches more front legroom, 1 inch more front shoulder room, .2 inches more rear headroom and 2.5 inches more rear shoulder room than the S5 Cabriolet.

Ergonomics Comparison

The M3’s standard easy entry system glides the driver’s seat back, making it easier for the driver to get in and out. The S5 doesn’t offer an easy entry system.

The M3’s standard power windows have a locking feature to keep children in the rear seat from operating them. Audi does not offer a locking feature on the S5’s standard power windows.

If the windows are left down on the M3 the driver can raise them all using the key in the outside lock cylinder; on a hot day the driver can lower the windows. The driver of the S5 can’t use the remote to operate the windows.

While driving with high beams on, sensitive light sensors available for the M3 detect other vehicles which could be blinded and automatically switch to low beams. The S5 doesn’t offer automatic dimming high beams.

When the M3 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.
