Safety

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

The RS 5 offers an optional Top and Corner View Cameras to allow the driver to see objects all around the vehicle on a screen. The RC 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 and the RC 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, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras and available lane departure warning systems.

Warranty

The RS 5’s corrosion warranty is 6 years longer than the RC 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’s warranty.

Engine

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

As tested in Road and Track the Audi RS 5 is faster than the Lexus RC F:

Fuel Economy and Range

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

Drivetrain

All-wheel drive, available in the RS 5, provides the best traction for acceleration in wet, dry, and icy conditions. In corners, all-wheel drive allows both outside wheels to provide power, balancing the car. This allows for better handling. The Lexus RC F is not available with all-wheel drive.

Brakes and Stopping

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

The RS 5 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 RC F doesn’t offer ceramic brake rotors.

Tires and Wheels

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

The RS 5’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 RC F’s 35 series tires.

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

Suspension and Handling

For a smoother ride and more stable handling, the RS 5’s wheelbase is 1.4 inches longer than on the RC F (108.9 inches vs. 107.5 inches).

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

Passenger Space

The RS 5 has 4.6 cubic feet more passenger volume than the RC F (84 vs. 79.4).

The RS 5 has 1.2 inches more front headroom, 4.4 inches more front shoulder room, 1.1 inches more rear headroom, 5.4 inches more rear legroom and 9.2 inches more rear shoulder room than the RC F.

Cargo Capacity

The RS 5 has a much larger trunk than the RC F (11.6 vs. 10.1 cubic feet).

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

To make loading groceries and cargo easier when your hands are full, the RS 5’s trunk can be opened just by kicking your foot under the back bumper, leaving your hands completely free. The RC F doesn’t offer a hands-free gesture to open its trunk, forcing you to put cargo down if your hands are full.

Ergonomics

The RS 5 offers an optional heads-up display that projects speed and other key instrumentation readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The RC F doesn’t offer a heads-up display.

The RS 5’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The RC F’s standard manually variable intermittent wipers have to be constantly adjusted.

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

The RS 5’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 RC F doesn’t offer an automated parking system.
