Both the Q4 e-tron and R2 have rear cross-traffic warning, but the Q4 e-tron has Automatic Brake Activation (automatically applies the brakes) to better prevent a collision when backing near traffic. The R2’s Rear Cross-Traffic Warning doesn’t automatically brake.

For better stopping power the Q4 e-tron’s brake rotors are larger than those on the R2:

The Q4 e-tron’s standard 235/55R19 front and 255/50R19 rear tires provide better handling because they have a lower 55 series front and 50 series rear profile (height to width ratio) that provides a stiffer sidewall than the R2’s standard 60 series tires. The Q4 e-tron 55 e-tron’s optional 235/45R21 front and 255/40R21 rear tires have a lower 45 series front and 40 series rear profile than the R2’s 60 series tires.

For better maneuverability, the Q4 e-tron 45’s turning circle is 6.2 feet tighter than the R2’s (33.5 feet vs. 39.7 feet). The Q4 e-tron 55’s turning circle is 2 feet tighter than the R2’s (37.7 feet vs. 39.7 feet).

The Q4 45 e-tron is 5 inches shorter than the R2, making the Q4 e-tron easier to handle, maneuver and park in tight spaces.

For excellent aerodynamics, the Q4 e-tron has standard flush composite headlights. The R2 has recessed headlights that spoil its aerodynamic shape and create extra drag.

To make loading groceries and cargo easier when your hands are full, the Q4 e-tron’s available liftgate can be opened and closed just by kicking your foot under the back bumper, leaving your hands completely free. The R2 doesn’t offer a hands-free gesture to open its liftgate, forcing you to put cargo down if your hands are full.

The Q4 e-tron Premium Plus offers an optional heads-up display that projects speed and driver assistance information readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The R2 doesn’t offer a heads-up display.

Heated windshield washer nozzles are standard on the Q4 e-tron to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The R2 doesn’t offer heated windshield washer nozzles.

To improve rear visibility by keeping the rear window clear, the Q4 e-tron has a standard rear wiper. The R2 doesn’t offer a rear wiper.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The Q4 e-tron Premium Plus offers available headlight washers to keep headlight output high. The R2 doesn’t offer headlight washers.

The Q4 e-tron’s optional rear and side view mirrors have an automatic dimming feature. These mirrors can be set to automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The R2 has an automatic rear view mirror, but its side mirrors don’t dim.

The Q4 e-tron Premium Plus’ Park Assist Plus can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. The R2 doesn’t offer an automated parking system.
