Safety

The A3 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 A3 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 A3 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.

Both the A3 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, rearview cameras, available lane departure warning systems, blind spot warning systems, rear parking sensors and rear cross-path warning.

Warranty

The A3 Sedan’s corrosion warranty is 5 years longer than the G70’s (12 vs. 7 years).

Reliability

The Audi A3 Sedan’s engines use 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.

Regardless of its engine, the A3 Sedan’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) Genesis only offers an automatic engine start/stop system on the G70 2.0T Automatic.

Environmental Friendliness

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Audi A3 Sedan higher (7 out of 10) than the Genesis G70 (3). This means the A3 Sedan produces up to 24.5 pounds less smog-producing pollutants than the G70 every 15,000 miles.

Transmission

The A3 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

The A3 Sedan stops shorter than the G70:

Motor Trend

Tires and Wheels

For better traction, the A3 Sedan Premium Plus/Prestige’s optional tires are larger than the largest tires available on the G70 (235/35R19 vs. 225/40R19).

The A3 Sedan Premium Plus/Prestige’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 3.3T/Dynamic/Sport’s 40 series front tires.

Suspension and Handling

The A3 Sedan Premium Quattro handles at .92 G’s, while the G70 Sport pulls only .89 G’s of cornering force in a Motor Trend skidpad test.

The A3 Sedan Premium Quattro executes Motor Trend’s “Figure Eight” maneuver quicker than the G70 Sport (25.6 seconds @ .71 average G’s vs. 26 seconds @ .68 average G’s).

Chassis

The Audi A3 Sedan may be more efficient, handle and accelerate better because it weighs about 300 to 550 pounds less than the Genesis G70.

The A3 Sedan is 8.9 inches shorter than the G70, making the A3 Sedan easier to handle, maneuver and park in tight spaces.

As tested by Car and Driver while under full throttle, the interior of the A3 Sedan Premium Quattro is quieter than the G70 Dynamic (73 vs. 77 dB).

Cargo Capacity

The A3 Sedan has a much larger trunk than the G70 (12.3 vs. 10.5 cubic feet).

Ergonomics

If the windows are left open on the A3 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 A3 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 A3 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.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The A3 Sedan offers available headlight washers to keep headlight output high. The G70 doesn’t offer headlight washers.

The A3 Sedan Prestige’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.

Model Availability

The Audi A3 comes in convertible, sedan and station wagon bodystyles; the Genesis G70 isn’t available as a convertible or station wagon.

Recommendations

Consumer Reports® recommends the Audi A3 Sedan, based on reliability, safety and performance. The Genesis G70 isn't recommended.
