Safety

The 4 Series Gran Coupe has standard Active Headrests, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Active Headrests system moves the headrests forward to prevent neck and spine injuries. The A6 doesn’t offer a whiplash protection system.

Both the 4 Series Gran Coupe and the A6 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, rearview cameras, available all wheel drive, crash mitigating brakes, lane departure warning systems, blind spot warning systems and around view monitors.

Warranty

BMW pays for scheduled maintenance on the 4 Series Gran Coupe for 3 years and 36,000 miles. BMW will pay for oil changes, lubrication and any other required maintenance. Audi only pays for the first scheduled maintenance visit on the A6.

There are over 13 percent more BMW dealers than there are Audi dealers, which makes it easier should you ever need service under the 4 Series Gran Coupe’s warranty.

Tires and Wheels

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires available on the 4 Series Gran Coupe can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The A6 doesn’t offer run-flat tires.

Chassis

The BMW 4 Series Gran Coupe may be more efficient, handle and accelerate better because it weighs about 350 to 600 pounds less than the Audi A6.

The 4 Series Gran Coupe is 11.7 inches shorter than the A6, making the 4 Series Gran Coupe easier to handle, maneuver and park in tight spaces.

Passenger Space

Ergonomics

The 4 Series Gran Coupe’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 A6 doesn’t offer an automated parking system.
