Compare the2023 Audi S3VS 2023 Genesis G70

The S3’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The G70 doesn’t offer pre-crash pretensioners.

Both the S3 and G70 have child safety locks to prevent children from opening the rear doors. The S3 has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The G70’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.

The Audi S3 has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The G70 doesn’t offer a front passenger side knee airbag.

The S3 has a standard Secondary Collision Brake Assist, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The G70 doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the S3. But it costs extra on the G70.

Both the S3 and the G70 have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front 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, lane departure warning systems, rearview cameras, available blind spot warning systems and rear cross-path warning.

The S3’s corrosion warranty is 5 years longer than the G70’s (12 vs. 7 years).

The Audi S3’s engine uses a cast iron block for durability, while the G70’s engines use an aluminum block. Aluminum engine blocks are much more prone to warp and crack at high temperatures than cast iron.

The S3’s 2.0 turbo 4-cylinder produces 54 more horsepower (306 vs. 252) and 35 lbs.-ft. more torque (295 vs. 260) than the G70 2.0T’s standard 2.0 turbo 4-cylinder.

On the EPA test cycle the S3 gets better mileage than the G70:

Both the S3 and the G70 2.0T have a standard automatic start/stop engine feature to stop unnecessary fuel waste and pollution at stoplights and heavy traffic. All S3s have a standard disable switch for the system, so a driver can keep the engine from shutting off when the vehicle stops temporarily. A disable switch costs extra on the G70.

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Audi S3 higher (5 out of 10) than the Genesis G70 (3). This means the S3 produces up to 16.5 pounds less smog-producing pollutants than the G70 every 15,000 miles.

The S3 offers a standard sequential manual gearbox (SMG). With no clutch pedal to worry about and a fully automatic mode, an SMG is much more efficient than a conventional automatic but just as easy to drive. The G70 doesn’t offer an SMG or a conventional manual transmission.

For better stopping power the S3’s front brake rotors are larger than those on the G70:

The S3’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs standard on the G70 2.0T are solid, not vented.

In an emergency stopping situation, many drivers don’t press the brakes with enough force to stop the vehicle in the shortest distance. The S3 has a standard brake assist system to detect emergency braking situations (by how hard and how quickly the brake pedal is pressed) and then automatically apply maximum braking immediately in order to help prevent a collision. The G70 doesn’t offer a brake assist feature.

For better traction, the S3’s optional tires are larger than the largest tires available on the G70 (235/35R19 vs. 225/40R19).

The S3’s optional tires provide better handling because they have a lower 35 series profile (height to width ratio) that provides a stiffer sidewall than the G70’s 40 series front tires.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires available on the S3 can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The G70 doesn’t offer run-flat tires.

The S3 has standard front and rear gas-charged shocks for better control over choppy roads. The G70’s suspension doesn’t offer rear gas-charged shocks.

The S3 is 7.1 inches shorter than the G70, making the S3 easier to handle, maneuver and park in tight spaces.

The S3 has a 3500 lbs. towing capacity. The G70 has no towing capacity.

J.D. Power and Associates surveys of service recipients show that Audi service is better than Genesis. J.D. Power ranks Audi 8th in service department satisfaction (above the industry average). With a 29% lower rating, Genesis is ranked 23rd.

If the windows are left open on the S3 the driver can close them all at the outside door handle or from a distance using the remote. On a hot day the driver can lower the windows from a distance using the keyless remote. The driver of the G70 can only operate the windows from inside the vehicle, with the ignition on.

The S3’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 G70’s standard manually variable intermittent wipers have to be constantly adjusted.

Heated windshield washer nozzles are standard on the S3 to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The G70 doesn’t offer heated windshield washer nozzles.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The S3 Prestige has standard headlight washers to keep headlight output high. The G70 doesn’t offer headlight washers.

The S3’s Park Assist can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The G70 doesn’t offer an automated parking system.

The S3 will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the S3 will retain 50.76% to 50.94% of its original price after five years, while the G70 only retains 43.59% to 44.28%.
