Compare the2026 BMW i5VS 2025 Audi A6 e-tron

Over 200 people are killed each year when backed over by motor vehicles. The i5 has a standard 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 A6 e-tron doesn’t offer automatic braking for stationary objects directly to the rear.

Both the i5 and the A6 e-tron 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, crash mitigating brakes, post-collision automatic braking systems, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors and available around view monitors.

BMW pays for scheduled maintenance on the i5 for 3 years and 36,000 miles. BMW will pay for tire rotations, cabin filter replacement, brake fluid replacement, inspections, and any other required maintenance. Audi only pays for the first scheduled maintenance visit on the A6 e-tron.

There are over 14 percent more BMW dealers than there are Audi dealers, which makes it easier should you ever need service under the i5’s warranty.

The i5 has more powerful engines than the A6 e-tron:

As tested in Car and Driver the i5 M60 electric motors is faster than the Audi A6 e-tron electric motor:

For better stopping power the i5’s brake rotors are larger than those on the A6 e-tron:

The i5 stops much shorter than the A6 e-tron:

For better traction, the i5 has larger standard tires than the A6 e-tron (245/45R19 vs. 225/55R19). The i5’s optional tires are larger than the largest tires available on the A6 e-tron (F:255/35R21 & R:285/30R21 vs. F:235/45R20 & R:265/40R20).

The i5’s standard tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the A6 e-tron’s 55 series front and 50 series rear tires. The i5’s optional 255/35R21 front and 285/30R21 rear tires have a lower 35 series front and 30 series rear profile than the A6 e-tron’s 45 series front and 40 series rear tires.

For better ride, handling and brake cooling the i5 offers optional 21-inch wheels. The A6 e-tron’s largest wheels are only 20-inches.

The i5 M60 offers active sway bars, which help keep it flat and controlled during cornering, but disconnect at lower speeds to smooth the ride and offer greater off-road suspension articulation. This helps keep the tires glued to the road on-road and off. The A6 e-tron doesn’t offer an active sway bar system.

The i5 M60 offers an available adjustable active suspension system, which counteracts cornering forces actively, limiting body roll and improving handling and stability. Audi doesn’t offer an active suspension on the A6 e-tron.

For a smoother ride and more stable handling, the i5’s wheelbase is 1.8 inches longer than on the A6 e-tron (117.9 inches vs. 116.1 inches).

The i5 M60 xDrive handles at .96 G’s, while the A6 e-tron Prestige pulls only .88 G’s of cornering force in a Motor Trend skidpad test.

The i5 M60 xDrive executes Motor Trend’s “Figure Eight” maneuver 2.2 seconds quicker than the A6 e-tron Prestige (23.9 seconds @ .86 average G’s vs. 26.1 seconds @ .74 average G’s).

For better maneuverability, the i5 eDrive40’s turning circle is 2 feet tighter than the A6 e-tron’s (38.4 feet vs. 40.4 feet). The i5 M60 xDrive’s turning circle is 1.4 feet tighter than the A6 e-tron’s (39 feet vs. 40.4 feet).

The i5 has .3 inches more front headroom, 1 inch more front shoulder room and 1.3 inches more rear legroom than the A6 e-tron.

With its sedan body style, valet key, locking rear seatbacks and remote trunk release lockout, the i5 offers cargo security. The A6 e-tron’s hatchback body style, non-lockable folding seat and non-lockable remote release defeat cargo security.

Unlike the driver-only memory seat and mirrors in the A6 e-tron, the i5 has standard driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position, outside mirror angle, climate settings and radio stations and the front passenger seat also adjusts to the new passenger’s preset preferences.

A power rear sunshade and manual rear side window sunshades are optional in the i5 to help block heat and glare for the rear passengers. The A6 e-tron doesn’t offer a rear or rear side window sunshades.

The i5 offers optional massaging front seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the A6 e-tron.

The i5’s Parking Assistant Plus can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. Optional Remote Control Parking will park and retrieve your car remotely: press a button and watch it park itself. This is ideal for tight locations. The A6 e-tron Premium Plus/Prestige’s automatic parking system does not offer parking by remote control.
