Safety

The S3 Sedan’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.

For enhanced safety, the front and rear seat shoulder belts of the Audi S3 Sedan are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The Genesis G70 has only front height-adjustable seat belts.

The S3 Sedan 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 Sedan. But it costs extra on the G70.

Both the S3 Sedan and the G70 have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, 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.

For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, with its optional front crash prevention system, and its headlight’s “Acceptable” rating, the Insurance Institute for Highway Safety grants the S3 Sedan the rating of “Top Pick” for 2018, a rating granted to only 85 vehicles tested by the IIHS. The G70 has not been tested, yet.

Warranty

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

Reliability

The Audi S3 Sedan’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.

From surveys of all its subscribers, Consumer Reports’ December 2018 Auto Issue reports that Audi vehicles are more reliable than Genesis vehicles. Consumer Reports ranks Audi 5 places higher in reliability than Genesis.

Engine

The S3 Sedan’s 2.0 turbo 4 cyl. produces 36 more horsepower (288 vs. 252) and 20 lbs.-ft. more torque (280 vs. 260) than the G70 2.0T’s standard 2.0 turbo 4 cyl. The S3 Sedan’s 2.0 turbo 4 cyl. produces 33 more horsepower (288 vs. 255) and 20 lbs.-ft. more torque (280 vs. 260) than the G70 2.0T Sport’s optional 2.0 turbo 4 cyl.

As tested in Motor Trend the Audi S3 Sedan is faster than the G70 2.0T 2.0 turbo 4 cyl. (automatics tested):

Fuel Economy and Range

On the EPA test cycle the S3 Sedan Auto gets better fuel mileage than the G70 2.0T AWD (22 city/29 hwy vs. 21 city/28 hwy).

Transmission

The S3 Sedan 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.

Brakes and Stopping

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

Tires and Wheels

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

The S3 Sedan’s standard tires provide better handling because they have a lower 40 series profile (height to width ratio) that provides a stiffer sidewall than the G70’s standard 45 series tires. The S3 Sedan’s optional tires have a lower 35 series profile than the G70 3.3T/Dynamic/Sport’s 40 series front tires.

Suspension and Handling

The S3 Sedan handles at .92 G’s, while the G70 Sport pulls only .89 G’s of cornering force in a Motor Trend skidpad test.

The S3 Sedan executes Motor Trend’s “Figure Eight” maneuver quicker than the G70 Sport (25.2 seconds @ .81 average G’s vs. 26 seconds @ .68 average G’s).

Chassis

The S3 Sedan is 8.6 inches shorter than the G70, making the S3 Sedan easier to handle, maneuver and park in tight spaces.

Ergonomics

If the windows are left open on the S3 Sedan 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 Sedan’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 Sedan 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.

The S3 Sedan Prestige’s 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 G70 doesn’t offer an automated parking system.
