Over 200 people are killed each year when backed over by motor vehicles. The 2 Series offers optional Active Park Distance Control that use rear sensors to monitor for objects to the rear and automatically apply the brakes to prevent a collision. The S5 doesn’t offer automatic braking for stationary objects directly to the rear.

The 2 Series 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. Only the S5 Premium Plus/Prestige offers a blind spot warning system.

To help make backing out of a parking space safer, the 2 Series has standard Cross Traffic Warning, helping the driver avoid collisions. Only the S5 Premium Plus/Prestige offers Rear Cross-Traffic Assist.

The 2 Series’ 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 S5 doesn’t offer a driver alert monitor.

Both the 2 Series 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, electronic stability systems to prevent skidding, crash mitigating brakes, post-collision automatic braking systems, daytime running lights, lane departure warning systems, rearview cameras, available all wheel drive and around view monitors.

BMW pays for scheduled maintenance on the 2 Series for 3 years and 36,000 miles. BMW will pay for oil changes, tire rotations, air filter replacements, cabin filter replacement, brake fluid replacement, inspections, and any other required maintenance. Audi only pays for the first scheduled maintenance visit on the S5.

There are over 14 percent more BMW dealers than there are Audi dealers, which makes it easier should you ever need service under the 2 Series’ warranty.

To reliably power the ignition and other systems and to recharge the battery, the 2 Series has a standard 170-amp alternator (210-amp - 2 Series 6 cyl.). The S5’s 150-amp alternator isn’t as powerful.

J.D. Power and Associates rated the 2 Series third among small premium cars in their 2023 Initial Quality Study. The S5 isn’t in the top three in its category.

J.D. Power and Associates’ 2023 Initial Quality Study of new car owners surveyed provide the statistics that show that BMW vehicles are better in initial quality than Audi vehicles. With 29 fewer problems per 100 vehicles, JD Power ranks BMW higher than Audi.

J.D. Power and Associates’ 2022 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 above average in long-term dependability. With 5 more problems per 100 vehicles in the first three years of ownership, Audi is rated below average.

From surveys of all its subscribers, Consumer Reports’ January 2024 Auto Issue reports that BMW vehicles are more reliable than Audi vehicles. Consumer Reports ranks BMW 10 places higher in reliability than Audi.

The M240i’s standard 3.0 turbo 6-cylinder produces 33 more horsepower (382 vs. 349) than the S5’s 3.0 turbo V6.

As tested in Car and Driver the M240i 3.0 turbo 6-cylinder is faster than the Audi S5:

On the EPA test cycle the 2 Series gets better mileage than the S5 Coupe:

The 2 Series’ launch control uses engine electronics to hold engine RPM’s precisely in order to provide the most stable and rapid acceleration possible, using all of the available traction. The S5 doesn’t offer launch control.

For better stopping power the M240i Coupe xDrive’s brake rotors are larger than those on the S5:

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires available on the 2 Series can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The S5 doesn’t offer run-flat tires.

For better handling and stability, the average track (width between the wheels) on the 2 Series is 1.1 inches wider in the rear than the track on the S5.

The 2 Series’ front to rear weight distribution is more even (51.4% to 48.6%) than the S5’s (56.7% to 43.3%). This gives the 2 Series more stable handling and braking.

The M240i Coupe xDrive handles at .98 G’s, while the S5 Prestige Coupe pulls only .94 G’s of cornering force in a Car and Driver skidpad test.

For better maneuverability, the 2 Series’ turning circle is 1.3 feet tighter than the S5’s (36.4 feet vs. 37.7 feet).

The BMW 2 Series may be more efficient, handle and accelerate better because it weighs about 300 to 400 pounds less than the Audi S5.

The 230i is 5.9 inches shorter than the S5, making the 2 Series easier to handle, maneuver and park in tight spaces.

The design of the BMW 2 Series amounts to more than styling. The 2 Series offers aerodynamic coefficients of drag from .28 to .3 Cd (depending on bodystyle and options). That is lower than the S5 (.31 to .32). A more efficient exterior helps the 2 Series go faster and keeps the interior quieter. It also helps the 2 Series get better fuel mileage.

The front grille of the 2 Series uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The S5 doesn’t offer active grille shutters.

Because it has more passenger and cargo room, the EPA rates the 2 Series a Compact car, while the S5 Coupe is rated a Subcompact.

The 2 Series has 4 cubic feet more passenger volume than the S5 Coupe (88 vs. 84).

The 2 Series Coupe has 2.4 inches more front headroom, .5 inches more front legroom, .6 inches more front shoulder room and 1 inch more rear shoulder room than the S5 Coupe.

The 2 Series Coupe has a much larger trunk than the S5 Coupe (13.8 vs. 10.9 cubic feet).

J.D. Power and Associates surveys of service recipients show that BMW service is better than Audi. J.D. Power ranks BMW 7th in service department satisfaction (above the industry average). With a 1% lower rating, Audi is ranked 8th.

In case of a sudden change of weather, the 2 Series offers an optional remote convertible top that can be raised from a distance to protect the interior of the vehicle from damage. On a hot day the 2 Series offers an optional remote opening feature, to lower the top from outside. The S5 doesn’t offer a remote top, so the driver will have to run to the car, get in, turn the ignition on and raise the top to prevent the interior from being damaged.

The 2 Series’ optional Parking Assistant can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. The S5 Prestige’s automatic parking system requires operating the brakes and transmission to safely park.

The 2 Series is available in both rear-wheel drive and all-wheel drive configurations. The S5 doesn’t offer a two-wheel drive configuration.
