The RS 5 Sportback’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The GS F doesn’t offer pre-crash pretensioners.

The RS 5 Sportback has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The GS F doesn’t offer all-wheel drive.

The RS 5 Sportback offers an optional Top and Corner View Cameras to allow the driver to see objects all around the vehicle on a screen. The GS F only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.

Both the RS 5 Sportback and the GS F have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, blind spot warning systems, rearview cameras, rear cross-path warning and available lane departure warning systems.


The RS 5 Sportback’s corrosion warranty is 6 years longer than the GS F’s (12 vs. 6 years).

There are over 26 percent more Audi dealers than there are Lexus dealers, which makes it easier should you ever need service under the RS 5 Sportback’s warranty.


The RS 5 Sportback’s 2.9 turbo V6 produces 54 lbs.-ft. more torque (443 vs. 389) than the GS F’s 5.0 DOHC V8.

Fuel Economy and Range

Regenerative brakes improve the RS 5 Sportback’s fuel efficiency by converting inertia back into energy instead of wasting it. The GS F doesn’t offer a regenerative braking system.

Brakes and Stopping

For better stopping power the RS 5 Sportback’s front brake rotors are larger than those on the GS F:

14.9 inches

The RS 5 Sportback offers optional heat-treated ceramic brake rotors, which last ten to twenty times as long as conventional cast iron rotors, don’t rust, don’t fade during repeated high speed braking, and their lighter weight contribute to better braking, handling and acceleration. The GS F doesn’t offer ceramic brake rotors.

Tires and Wheels

For better traction, the RS 5 Sportback has larger standard tires than the GS F (265/35R19 vs. 255/35R19). The RS 5 Sportback’s optional tires are larger than the largest tires available on the GS F (275/30R20 vs. 255/35R19).

The RS 5 Sportback’s optional tires provide better handling because they have a lower 30 series profile (height to width ratio) that provides a stiffer sidewall than the GS F’s 35 series tires.

For better ride, handling and brake cooling the RS 5 Sportback offers optional 20-inch wheels. The GS F’s largest wheels are only 19-inches.

Suspension and Handling

For better handling and stability, the track (width between the wheels) on the RS 5 Sportback is 1.7 inches wider in the front and 1.1 inches wider in the rear than on the GS F.


The RS 5 Sportback is 5.2 inches shorter than the GS F, making the RS 5 Sportback easier to handle, maneuver and park in tight spaces.

Passenger Space

The RS 5 Sportback has 1.4 inches more front headroom, .7 inches more front legroom and 2.3 inches more rear legroom than the GS F.

Cargo Capacity

The RS 5 Sportback’s standard rear seats fold to accommodate long and bulky cargo. The GS F doesn’t offer folding rear seats, only a ski pass-through.

To make loading and unloading groceries and cargo easier when your hands are full, the RS 5 Sportback’s power trunk can be opened or closed just by kicking your foot under the back bumper, leaving your hands completely free. The GS F doesn’t offer a power or hands-free opening trunk.

Servicing Ease

A Service Interval Display is standard on the RS 5 Sportback to save the owner time and money by calculating maintenance intervals based on odometer mileage. This takes the guesswork out of keeping your vehicle in top condition and helps it last longer. Lexus doesn’t offer a maintenance reminder on the GS F.


Heated windshield washer nozzles are standard on the RS 5 Sportback to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The GS F doesn’t offer heated windshield washer nozzles.

On extremely cold winter days, the RS 5 Sportback’s optional heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the car heater warms up. The GS F doesn’t offer a heated steering wheel.

The RS 5 Sportback’s optional Park Steering Assist can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The GS F doesn’t offer an automated parking system.
